Melbourne Cray Dives

Melbourne Cray Dives

Here at The Scuba Doctor we're often asked where is the best place to catch a Crayfish in Port Phillip Bay and/or out in Bass Strait near Melbourne, Victoria. Well first you need to know what you're hunting for. The official name for this great big delicious local red sea monster caught in the waters of Victoria is Southern Rock Lobster, Jasus Edwardsii. But most everyone around here just calls them Crays or Crayfish.

Diving for and catching a Crayfish is fantastic fun and very rewarding. However, it's a skill that usually requires practice and patience before you are continually successful. See How To Catch Crayfish.

Here we list the local crayfish diving sites we know about. Happy rock lobster hunting!

12lb Reef

Wall Dive Boat access
Crayfish Dive Site Inside Port Phillip Bay Open Water Rated Reef Dive Site Slack Water

Depth: 8 metres (26 feet) to 20 metres (66 feet)

12lb Reef is located on the Lonsdale Wall, inside Port Phillip. It was named after a massive crayfish that was caught there. The story goes that a cray diver caught site of the monster in its cave, and grabbed it. Maybe it's more accurate to say that the cray caught him! By the time he reached the surface, the two were still locked in a mortal struggle!

Nevertheless, there could well be more large crays still lurking here, so if you fancy your skills as a cray hunter it's definitely worth a look. The many overhangs and plentiful soft corals make this a popular and picturesque dive as well.

Divers have the opportunity to catch crayfish (Southern Rock Lobster) at this dive site. Remember your catch bag, current Victorian Recreational Fishing Licence, rock lobster measure, and cray tags. Please abide by all current fishing regulations if you intend to catch crays. See How To Catch Crayfish for practical cray hunting advice from The Scuba Doctor.

Boarfish Reef, by Jane Headley.

Situated in the famous Sponge Gardens, Boarfish Reef lies approximately halfway between Queenscliff and Point Lonsdale. It starts in approximately 10 metres of water and gradually increases in depth to around 22 metres in a system of interesting rock formations and overhangs and swim-throughs.

The reef provides protection and homes to a multitude of colourful growth, fish, and marine life. Commonly seen are the spectacular Blue Devil fish, Crayfish, curious Leather Jackets, nudibranchs, mosaic sea stars, yellow sea spiders and of course Boarfish. On occasion Port Jackson Sharks have been sighted snoozing in groups or singularly under rock ledges.

Near the southern end of the reef, in 10 metres of water wedged upright, is a large 4 metre Admiralty anchor encrusted with marine growth. On the northern tip of the reef a large sponge garden extends for approx 400 metres. One of the most popular dive sites and always enjoyable.

Captain Nitro Drop Off (aka The Drop-Off) is located on the Western end of Spectacular Reef, and consists of a series of walls that plunge to over 60 metres in 5 to 10 metre increments. This makes it a great dive for advanced levels. Huge boulders the size of houses are scattered over the area, lying where the ancient Yarra River deposited them. Midwater, large fish can often be spotted as they make their way into the bay, and if you are lucky seals and dolphins are also occasional visitors.

Castle Rock

Bommie Dive Boat access
Crayfish Dive Site Open Water Rated Outside Port Phillip Bay Reef Dive Site

Depth: 12 metres (39 feet) to 20 metres (66 feet)

Castle Rock is located outside Port Phillip Heads on the south west side in approximately 20 metres (66 feet) of water. It rises majestically out of a sandy bottom to around 12 metres (39 feet) on top.

The walls of this bommie have many undercuts, splits and ledges and with jagged rock turrets on top it's easy to see how this site got its name! The rock is around 200 metres (656 feet) in circumference and can be circled once or twice in a dive. The fixed depth, lack of current and easy navigation makes this the perfect boat dive for newer Open Water divers.

But don't spend all of your dive time just exploring the base of Castle Rock. There is a lot of very interesting marine life to be found on the top.

Castle Rock is a wonderful dive with a wide variety of creatures from Nudibranchs to Seastars, numerous fish life including Blue Devils hiding under the ledges and a possible sighting of Seadragons to be found under and around the rock. There is even a slim chance of a Cray or two under ledges at the bottom, or in nearby reef.

Great Crayfish Dive Site

The name Catch Bag Reef Drift originates back in the mists of time. The story goes that one day a cray diver of great notoriety had the largest cray he had ever seen in his catch bag. Unfortunately as he handed his gear to the boat the catch bag was lost along with the cray.

This drift is conducted on the flood tide over a kelp forest in the Lonsdale Bight between Point Lonsdale and Queenscliff in Port Phillip. This site also makes a great slack water dive.

During the drift you will encounter large fronds of kelp with broken sandstone reef, home to the Southern Rock Lobster (Crayfish) and Abalone. During the summer months, big schools of large Yellow Tail Kingfish can be seen.

Corsair Rock

The name Corsair Rock has sent shudders down the spine of many a seaman navigating Port Phillip Heads. The rock has been responsible for an extremely large number of shipwrecks and strandings.

Corsair Rock itself is 6 metres in diameter and covered by 3 metres of water. The rock is located 600 metres west of Rock Beacon and can usually be identified by the swell breaking above it. When conditions are favourable the kelp-covered top of the rock may be seen from the surface. When conditions such as this exist diving around Corsair Rock is at its best.

Depth: 16 metres (52 feet) to 27 metres (89 feet)

At the very Northern end of the Lonsdale reef system in Port Phillip lies Easter Bommie, also known as Sue's Grotto. No one really knows where the name originated, but everyone who has dived it knows it is a wonderful dive. Only divable at slackwater, the top is in around 16 metres on the Northern edge of the Bommie. Swimming North from the top, you will drop over the edge and you can descend to a maximum depth at the sandy base to around 27 metres. You can then follow the wall around to either the Southeast or the Southwest.

Crayfish are abundant in the Southeast. On a sunny day the light reflects from the sandy base making this site great for photography. Not dived as often as many other sites, so rather special. A great dive with lots of colourful soft corals and sponges and fans.

Giddiup

Reef Dive Boat access

Depth: 14 metres (46 feet) to 20 metres (66 feet)

Discovered and named by a Seinfeld fan who when 'sounding' over this area did a great Kramer impersonation and yelled Giddiup! when he noticed this dive site's spectacular looking formations. The name stuck.

Giddiup is approximately 1 kilometre from the Point Lonsdale Light and clear of the shipping channel, just outside Port Phillip Heads. It's an amazing area of Bommies and underwater rock formations.

The strong current flow in this area has created a nutrient rich environment and subsequently prolific marine growth and the associated marine life. But it's the amazing rock formations that make this dive site special.

The mark is on the eastern side of the reef, pretty close to an old cray pot. Turn right and follow reef like Castle Rock to a 10 metre long arch with Yellow Zoanthids underneath. Go through the arch and explore the reef scattered on the west side which is home to Cuttlefish and a family of Blue Groper. Almost certain to see White Barred Boxfish there as well.

The site is also known to fishing charters as a good spot for Kingfish.

Kelp Beds Reef

Reef Dive Boat access
Crayfish Dive Site Drift Dive Site Inside Port Phillip Bay Open Water Rated Reef Dive Site

Depth: 8 metres (26 feet) to 23 metres (75 feet)

Approximately midway between Point Lonsdale and Queenscliff is an area, which is marked on Admiralty charts as the Kelp Beds. Once upon a day, large strands of kelp extended up from a bottom of 15 metres to the surface where the fronds spread out to seemingly blanket areas of 50 square metres or more. Today, due to undetermined reasons, (water temperature, urchins, and boat traffic) this area has lost the forest kelp but retains a top covering of a thicker kelp species on top of the rock formations and bommies.

The area is now most noted for being in the Sponge Gardens, with all the relevant draw cards for photographers, fish spotters and Crayfish hunters. The currents can run fast and strong, providing the fresh nutrients for the marine life and because of this the area should be dived at slack water or as a drift dive.

Kelp Beds Reef Drift is conducted on the flood tide over a macro cysts kelp forest in Lonsdale Bight between Point Lonsdale and Queenscliff. This dive site also makes a great slack water dive, with depths ranging from 10 to 21 metres. During the drift dive you will encounter large fronds of kelp with broken sandstone reef, often home to the Southern Rock Lobster (Crayfish) and Abalone. During the summer months, big schools of large Yellow Tail Kingfish can be seen, or large schools of Old Wives.

Knawesome Bommie, also known as Al's Bommie (after Alan Beckhurst), is located inside the bay on the top North East section of the Lonsdale Wall system. This large bommie rises from 40 metres to 22 metres with lots of other smaller ones scattered around it. Because it is located in the shipping channel this rarely dived site is teaming with marine life and a fantastic area for taking photographs.

Knawesome Reef is covered in soft corals sponges and fans, with some overhanging ledges and small caves. It is outside the Marine Park and Crayfish are known to be caught in the area. Other common fish species include the Southern Blue Devil, Magpie Morwong, Boarfish, schools of Pike and many others.

Lonsdale Arches

Depth: 12 metres (39 feet) to 18 metres (59 feet)

Discovered and named by one of the great local diving identities, Lonsdale Arches is spectacular. Approximately one kilometre from the Point Lonsdale Light and clear of the shipping channel, just outside Port Phillip Heads is an amazing area of Bommies and underwater rock formations.


Lonsdale Arches from Alan Beckhurst on Vimeo.

The sandstone reef has been carved into intricate structures including arches and tunnels. The water movement feeds a rich covering of encrusting invertebrates inside the structures, while Ecklonia kelp dominates the outside. This a perfect habitat for many of southern Australia's unique critters, and a nature lovers delight.

The strong current flow in this area creates a nutrient rich environment and subsequently prolific marine growth and the associated marine life. But it's the amazing rock formations that make this dive site special. This site has a couple of amazing swim throughs that are very safe easy to enter.

A favourite spot for catching Crayfish, possibly sightings of Cuttlefish, Draughtboard or Port Jackson Sharks sleeping under ledges, and the odd seal has been known to pop down and check out what is going on here.

Nepean Wall

Nepean Wall runs East to West just outside Port Phillip Heads on the Point Nepean side. To go over the wall you swim South from the shot. Descending to your desired depth you can swim in either direction along the wall, but it is important that you return to the shot for your ascent as the current here turns very quickly. It is also a good idea to keep your bottom time shorter on this dive.

This dive is only done on the ebb turning to flood so that at the end of your dive the current will bring you back into Port Phillip. The wall along here is amazing with lots of soft coral and sponges but slightly different coverage than the Lonsdale Wall side. The odd Crayfish is collected here too. The fish life is amazing and this quite often brings Seals into the area.

Depth: 30 metres (98 feet) to 42 metres (138 feet)

New Deep Bommie sits in approx 42 metres water. If you swim along the West side first (with the Bommie on your left side) you'll come to high peaks rising up from 42 metres to 34 metres, which create gullies that divers can swim through.

When you swim through the last one you'll come to an open expanse of rock usually inhabited by a large school of bull's eyes. At this point the diver can head North to the centre top of the New Deep Bommie and search for a cave opening at about the 34 metre mark. The opening leads to a swim through which is only a few metres in length with the Odd Wrasse passing you by.

Or the diver can stay on the previous heading an encircle the entire New Deep Bommie where there are rich colours in the form of soft sponges dotted about the face of the Bommie and fish such as Wrasse, Horseshoe Leather Jackets, Sweep, plus more.

North Wall Corner is is an amazing dive, situated at the Northern end of the Lonsdale Wall in Port Phillip. Lonsdale Wall runs South to North, and at this point it turns and runs West to East. Here in the corner the current has scoured quite a deep area. The walls tower vertically here with amazing splits and overhangs sheltering an amazing variety of soft coral and sponges.

Generally this dive is done on Slack Water at the end of the Flood so that it's at its clearest. In this dive it is best to swim along the East West wall first and then return onto the North South wall before the current picks up.

Ramsden Reef

Reef Dive Boat access
Advanced Open Water Rated Crayfish Dive Site Inside Port Phillip Bay Reef Dive Site Subject to Shipping Slack Water

Depth: 20 metres (66 feet) to 30 metres (98 feet)

The wreck of the Eliza Ramsden has been a favourite of divers for a number of decades. However because of its location, and the navigational skill required to find it, many divers have been disappointed and failed to find it. This has resulted in considerable diving being done around the wreck, which is fortunately the location of some magnificent reef areas — hence the name Ramsden Reef.

The most popular reef is located approx 75 metres (246 feet) from the wreck, directly towards Pope's Eye. Large Leatherjackets, Sweep, Trumpeter, and Trevally frequent the area with Blue Devil fish complimenting the gorgonia under the ledges where crayfish may also be found.

The Reef slopes at about a 60 degree angle down to a sandy bottom. The slope is more severe in several places and it is here that the undercut caves are usually found. The reef is only about 60 metres long and consequently, can be difficult to find.

At each end it breaks into rubble and sand, levelling at 20 metres in the east and 30 metres at the western end.

The area must be dived at slack water as the currents race through much too quickly to hang on to the reef. Ramsden Reef is in the shipping lanes and diving may only be conducted when no shipping is expected.

A fantastic underwater cliff just outside Port Phillip Heads on the south east side. The currents through here dictate this dive only be conducted on a slack water at the end of the flood tide and even then only when conditions are calm outside the bay. The passage of the current here runs along the wall and can be extremely fast.

There are a lot of Crayfish to be caught along the top of the wall. The wall itself is very steep with large overhangs and beautiful colours. The other great thing about this dive is that almost every dive somebody gets to see Sharks swimming along the wall. They do tend to swim about 10 to 15 metres from the wall and just cruise past checking things out. The sharks are Seven Gills and are listed as harmless. They look a little like Grey Nurse Sharks and can grow up to 3 metres long.

Sorrento Back Beach

Reef Dive Shore access
Crayfish Dive Site Ideal For Snorkelling Open Water Rated Outside Port Phillip Bay Reef Dive Site Abalone Dive Site

Depth: 2 metres (6.6 feet) to 20 metres (66 feet)

Level: Advanced Open Water and beyond

Ideal Conditions:
The sea needs to be flat with no swell.

What To Expect:

Out through Port Phillip Heads past Point Nepean to the south east lies the Sorrento Back Beach dive site. Although some of this area can be dived as a shore dive a lot can't. It's these areas we venture to by dive boat in order to explore the lovely reefs and rocky outcrops.

Crayfish Dive

The incredible ledges and overhangs here are usually a haven for Crayfish, snapper and other lovely edible and photogenic critters. A great dive when the seas are calm and the wind has blown from the north for a few days.

Sorrento Back Beach Shore Dives

The three main dive sites from the shore at Sorrento Back Beach are:

  1. the platforms by the headland,
  2. a reasonable snorkel southwards out to the areas around Darby Rock, or
  3. after a 10 to 15 minute walk around the coastline to the west, the enclosed gullies at Sphinx Rock.

The walk at Sorrento Back Beach is slightly easier then many of the other back beach dives. Though during the summer months it gets really busy as lots of families bring down the kids to swim in the large artificial rock pool. Go early to get a decent park!

Be sure to always take a dive flag and a knife. You might also want to take a catch bag down here too! Abalone and crayfish can be found here. Be sure to always carry the appropriate measuring device as the rangers have been known to join you in the water as well as wait on shore.

It is recommended to dive here the first time with someone who is familiar with the area and has dived here before. Be aware of the walks involved. It's not for the unfit!

Divers have the opportunity to catch crayfish (Southern Rock Lobster) at this dive site. Remember your catch bag, current Victorian Recreational Fishing Licence, rock lobster measure, and cray tags. Please abide by all current fishing regulations if you intend to catch crays. See How To Catch Crayfish for practical cray hunting advice from The Scuba Doctor.

Divers have the opportunity to catch abalone at this dive site. Remember your catch bag, legal abalone tool, current Victorian Recreational Fishing Licence, and abalone measure. Please abide by all current fishing regulations if you intend to catch abalone. See How to Catch Abalone for practical abalone hunting advice from The Scuba Doctor.

Always keep an eye on sea conditions throughout any dive on the Back Beaches. Please read the warnings on the web page Diving the Back Beaches before diving or snorkelling this site.

Spec Reef

Reef Dive Boat access
Advanced Open Water Rated Crayfish Dive Site Deep Rated Inside Port Phillip Bay Subject to Shipping Slack Water Technical Rated

Depth: 22 metres (72 feet) to 60 metres (197 feet)

Spec Reef (aka Spectacular Reef) is part of the former Yarra River bed and lies in the South Channel, Port Phillip, Victoria and is therefore subject to shipping traffic. The area is quite large and offers many different dive sites. All dives are characterised by a spectacular wall which has large undercuts housing Crayfish, Blue Devilfish, beautiful soft corals, and an abundance of other life including Silver Trumpeter, Leather Jackets, the Rosy Wrasse, and inquisitive White Ear, along with literally thousands of small baitfish.

Spec Reef is very aptly named. The scenery, rock formations, the sheer drop-offs and the most abundant fish life in the Bay, make it a special place.

On days of good visibility you will understand why this area is called Spectacular Reef. The terrain is quite dramatic with large deep ledges. It can only be dived on the slack water when there is no shipping as it is right in the middle of the channel. This makes another elusive site but well worth the effort. It starts in 15 metres and runs East to West with deeper water down to over 33 metres to the South. The current here is not a strong as in other places, which means that this dive can be done on either of the slack waters.

Spec Reef has an unusual combination of huge undercuts and sheer drop offs. The sheer sides of the reef have fantastic overhangs and lovely colours in the sponge life. The area is big on sponges and very, very fishy. This is truly one of the prettiest dives in the bay — in fact it's spectacular.

Spot G, by Jane Headley.

Named after a local diving identity, the Spot G dive site is remarkably hard to find. Some even say it doesn't exist, but it does. It's a stunning part of the Lonsdale Wall cliff system. The wall here runs North to South with deeper water to the East. The wall has some huge splits or cracks in the area with a few pieces having broken away from the wall itself. This is wall diving at its best. Lots of fish and some incredible colours make this photographer's heaven.

Depth: 20 metres (66 feet) to 25 metres (82 feet)

Sub Reef was accidentally discovered by dive boat skippers who thought they were positioned over the wreck of the J4 Submarine in the area. (It does look remarkably like a submarine on the sounder.) It's a great dive on its own merit and is ideal as a training dive or for those wanting to see some pristine temperate water reef and schools of the local fish life.

The Abyss is located just inside Port Phillip Heads on the Point Nepean side. The wall here is 20 metres to 40 metres deep and faces Northeast. Some distance off the wall lies a very large bommie over 100 metres east to west and perhaps 40 metres north to south.

This dive site is prone to strong currents and swells and can only be dived during slack water turning to a flood. Because of this, caution should be exercised on this dive but the scenery makes it well worthwhile.

Advanced Open Water Rated Crayfish Dive Site Deep Rated Inside Port Phillip Bay Reef Dive Site Subject to Shipping Slack Water Technical Rated

Depth: 22 metres (72 feet) to 60 metres (197 feet)

The Cathedral dive site is situated on a reef that runs East to West on the eastern edge of the main shipping channel. The top of the reef is in 20 plus metres, most of the dive at this site will be spent in the 30 to 40 metre range. The name arises from the fantastic Pinnacle and Bommies that rise 4 or 5 metres above the top of the reef. There is also a huge cave at 32 metres, with a swim-through at the back, leading out to the top of the wall this site can only be dived when there is no shipping and at slack water at the end of the ebb tide.

The Grotto is named after the many small caves and large overhangs that form this site. Located on top of the Lonsdale Wall system, this area is teaming with marine life and a photographers dream. This site gradually increases in depth to around 23 metres in a system of interesting rock formations and overhangs and swim-throughs.

There are spectacular Blue Devil fish, Crayfish, curious Leather Jackets, nudibranchs, mosaic sea stars, yellow sea spiders, Magpie Perch and Boarfish. On occasion Port Jackson Sharks have been sighted snoozing in groups or singularly under rock ledges. One of the most popular dive sites, always enjoyable and great for new divers.

The Links

Wall Dive Boat access
Advanced Open Water Rated Crayfish Dive Site Inside Port Phillip Bay Reef Dive Site Subject to Shipping Slack Water

Depth: 16 metres (52 feet) to 60 metres (197 feet)

The Links is named for a massive anchor chain lost from the Japanese freighter the Ningan Maru in the late 1980s. The vessel suffered a steering failure just inside the Heads and with the strong incoming tide was quickly pushed towards the shoreline at Shortland's Bluff. The pilot gave the order to drop the anchor in order to prevent the vessel being driven ashore. Later when the problem was rectified the anchor chain had become fouled on the seabed and was unable to be recovered and was cut free.

Today the anchor chain hangs like a necklace draped over the wall and over Bommies as it drops from 18 metres to 60 metres at the bottom. The chain is now overgrown in beautiful sponges and is a fantastic sight.

The Pinnacles

Reef Dive Boat access

Depth: 9 metres (30 feet) to 38 metres (125 feet)

Located in the South Eastern area of Phillip Island, well outside Port Phillip Heads and West past Point Nepean in Bass Strait.

The Pinnacles are a collection of large pinnacles of rock rising from a rocky bottom at 38 metres up 9 metres from the seabed. The height of these Bommies has attracted large amounts of fish life and they are also covered in lovely coloured soft corals and sponges.

Best launching from Newhaven on Phillip Island, as it's a long way from The Heads and Point Nepean. Use a plough or sarca anchor in preference to a sand anchor. Anchor in the deep section and check that the swell and wind is holding your anchor line clear of rising reef structure.

The Plateau

Reef Dive Boat access

The Plateau is a reef dive in the middle of the Port Phillip Heads. The Plateau is a huge rocky platform in around the 16 metre range, winding its way around the edge of this platform is the Entrance Deep. This is the deepest water in Victoria, originally part of the River Yarra. Depths at the bottom of this area are between 40 metres and 103 metres.

The slack water period here is short, hard to pick, and the currents a little unpredictable. Then of course there is the problem of the dive site being in the shipping channel. Diving is only possible when sea conditions, the tide, and shipping allow. Despite all of that this area is awesome with some fantastic rock formations sheltering an amazing array of sea life.

The Supermarket area is a large rocky outcrop that runs out from Lonsdale Beach outside Port Phillip Heads. There used to be an outfall from the abattoir on the other side of the sand dunes many years ago, but this has now gone.

The rock outcrop used to be home to hundreds of Crayfish, Port Jackson Sharks and Wobbegongs. The Crayfish are not as plentiful here as they once were but they can still be found. This site is only suitable for diving when conditions are calm as it is quite prone to surge from swell that might be running.

Also a great sight to see the giant black Stingrays that we have here in Port Phillip Bay. The relative shallowness of the water here allows a lot of light and nice long bottom times. A great dive to spend just admiring the colours of our temperate water reefs.

Divers have the opportunity to catch crayfish (Southern Rock Lobster) at this dive site. Remember your catch bag, current Victorian Recreational Fishing Licence, rock lobster measure, and cray tags. Please abide by all current fishing regulations if you intend to catch crays. See How To Catch Crayfish for practical cray hunting advice from The Scuba Doctor.

Twin Bommies is exactly as its name would suggest, two large rock Bommies standing up from the 18 metre seabed just off Point Lonsdale outside of Port Phillip in Bass Strait. The Bommies have a large community of fish life and are covered in bright soft corals and sponges. A great dive with lots of photo opportunities, not to mention the odd Crayfish or two.

Part of the Nepean Wall, this is a great site for those chasing the elusive Crayfish. The wall here has its top in around 18 metres and drops to the south to 60 metres. While the wall here is spectacular the majority of Crayfish and in fact the dive will be on the plateau.
