Emergency Air Systems
The solution to preventing injury from a failed surface air supply while diving is simple but it costs money — carry an accessory emergency air source and regulator. The money so spent on this life saver may well be your best investment ever!
A suitable emergency air source converts a panic ascent into a leisurely trip to the surface. Compared to the overall cost of the diving, boat and other equipment, the cost is relatively small.
Please ensure your accessory air source has a scuba cylinder of the appropriate size for the maximum depth you're diving to. You should plan to have enough air for around 15 minutes of breathing on the ascent with a decompression stop if necessary. Smaller all-in-one air regulators generally do not contain enough gas for a controlled ascent, although they are definitely far better than no spare air at all.
The Scuba Doctor recommends a triple-redundant air supply system should be used while hookah diving. The primary air supply is a low pressure (LP) hookah compressor. The secondary is the diver carried bailout or emergency air system. Finally, in an emergency requiring additional time for diver extraction, there should be a scuba cylinder topside, suitably configured so that it can be used to provide air to the hookah diver.
Please read Introduction to Hookah Diving for more information about things you need to consider with a hookah diving setup.
The Pipelines, Indented Head

The Pipelines | © Phil Watson
Depth: 1 m (3.28 ft) to 4 m (13 ft)
Level: Open Water and beyond.
The Pipelines at Indented Head on the Bellarine Peninsula are the water intake for the Great Southern Water onshore abalone farm. They run out about 500 metres towards Governor Reef. The end of the pipelines is marked with a yellow buoy.
Nice sponge growth under the pipelines, and many rays also hang out underneath. The tops of the pipelines are dominated by kelp and home to lots of filter feeding ascidians.
Be careful of boats in this area and take a dive flag buoy.
See WillyWeather (Indented Head) as a guide for the tide times and the height of the tide.
Wathaurong (Wadda-Warrung) country
Traditional Owners — This dive site is in the traditional Country of the Wathaurong (Wadda-Warrung) people of the Kulin Nation. This truly ancient Country includes the coastline of Port Phillip, from the Werribee River in the north-east, the Bellarine Peninsula, and down to Cape Otway in the south-west. We wish to acknowledge the Wathaurong as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging. We acknowledge Bunjil the Creator Spirit of this beautiful land, who travels as an eagle, and Waarn, who protects the waterways and travels as a crow, and thank them for continuing to watch over this Country today and beyond.

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.
