Spearfishing Shafts and Points

Speargun Shafts: Spearfishing shafts come in a variety of lengths, sizes and styles to match your gun, target and style. Longer shafts match your barrel length and wider diameter shafts carry more weight and hit harder. Shafts have two common styles with either a fixed Tahitian point or a threaded tip to fit different heads to. Different metals act differently in the water with some being more flexible and corrosion resistant and others that are less likely to bend.

It's important to fit your speargun with the correct spear shaft. The thicker your spear shaft is, the more power it will have pushing through objects. Therefore, if you are hunting big pelagic fish you will want a thick speargun shaft, such as an 8 mm shaft.

It's important to remember that thicker shafts, if used around the reef or rocks, will hit the reef or rocks with more impact and could therefore become damaged or bent. If you are just starting out a 6.5 mm or 7 mm speargun shaft is ideal and will provide plenty of punch while still surviving accidental contact with rocks or reef.

When ordering, please remember, the listed sizes are the length of shaft you are ordering, not the measurement of the gun it is intended to fit. Please ensure you measure your existing shaft and re-order that size.

Spear Heads: Spearheads come in all different shapes and sizes depending on what and where you are hunting. Simple Tahitian shafts are faster and more accurate but can pass straight through some targets when you may need to hit the fish with more energy to dispatch it properly. Multi-point and heavier heads give you more chance of hitting your target across one axis and can transfer all of the energy of the shot quickly to dispatch the fish.

The Wyrallah (aka Wyralla and Whyrallah) sank with the loss of six lives at Port Phillip Heads after a collision with the SS Dilkera, on 8 April 1924, while on a voyage from Melbourne to Gippsland Lakes.

Diving the Wyrallah Shipwreck

The remains of the Wyrallah were rediscovered in the 1970s by divers, Alan Farman and Gordon Baker, while recovering a snagged cray pot for a local fisherman.

The Wyrallah is located in the middle of The Rip, and in the fairway of huge ships. Given the degree of difficulty of the site, combined with the short window of opportunity for diving, it's rarely dived.

Bass Strait Warning: Always keep an eye on sea conditions throughout any shore or boat dive in Bass Strait on Victoria's coastline. Please read the warnings on the web page diving-in-bass-strait before diving or snorkelling this site.

The Rip & Tides Warning: Always keep an eye on sea conditions throughout any shore or boat dive within "The Rip" (aka "The Heads"). This is a dangerous stretch of water, where Bass Straight meets Port Phillip, which has claimed many ships and lives. Please read the warnings on the web page diving-the-rip before diving or snorkelling this site.

Wyrallah Shipwreck History — Built in 1867

The Wyrallah was a schooner rigged, steel twin screw steamer of 302 tons, built in 1867, by Mort's Dock & Engineering Co, of Balmain, NSW. The vessel was built on a length of 140 ft (43 m), a breadth of 22.3 ft (6.8 m) and a depth of 13.2 ft (4.02 m).

Built for the northern rivers of NSW trade, and chartered for other services at times: e.g. Esperance-Albany mail service; New Caledonia; coal from Newcastle to Bairnsdale.

The Wyrallah was later owned by the Gippsland Steamers Pty. Ltd., and used exclusively in the Gippsland Lakes to Melbourne trade.

Wyrallah Sinking — Wrecked 8 April 1924

On 8 April 1924, the steamer Wyrallah was on its usual run to the Gippsland Lakes from Melbourne, with 2 passengers and 13 crew, under the command of Captain Richard Bracken, when it collided with the SS Dilkera with the loss of six lives.

Travelling at 6 knots at 10.20 p.m., the Wyrallah was nearly cut in half by Dilkera, which was travelling at full speed. The Wyrallah sank within 10 minutes. Searchlights from Fort Queenscliff trained on the area in search for victims and salvage.

The Wyrallah's master was blamed by Court of Marine Inquiry — his first command. Primary cause was determined as the the Wyrallah being on wrong side of the channel. The master of the Wyrallah was suspended for 12 months. The Master of the Dilkera censured for omitting to render upmost assistance after the collision.

The lifeboat had taken two hours to arrive. Court recommended that the lifeboat (oar and sail), be replaced by a motorboat.

Robert G. Menzies, later to become Australia's longest serving Prime Minister, represented the Wyrallah's owners as a junior counsel at the Inquiry.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
