Meet the site

Little Saigon sits about 240 m north-east of Cape Baily Lighthouse and is the southern half of a pair of wall dives with Big Saigon, 140 m to the north. McFadyen's group named it after the number of Vietnamese fishers they saw on the rocks and in boats in the area when they first dived it. Like Big Saigon, it lies on a stretch of coast long shunned because of the Cronulla sewage outfall and the Kurnell refinery, and it is still dived only rarely despite being just 10–15 minutes from the Port Hacking ramps. The reef top is at about 20 m, a little deeper than Big Saigon, and the wall runs north–south, dropping to around 24–25 m, with smaller walls stepping down past 32 m – McFadyen has not yet found where the reef meets the sand. The wall face is scalloped with overhangs and at least one small swim-through, and it continues north for about 200 m with consistent character. Gullies formed by very large boulders break the line of the wall, and away from it scattered boulders of all sizes create more shelter. The encrusting growth is excellent – sponges in many colours, sea squirts and small gorgonians – and the fish life is prolific, with one-spot pullers, silver sweep, small seapike and yellowtail schooling along the face and mosaic and six-spined leatherjackets among the boulders. McFadyen rates it an excellent dive site. Combined with the Hilda wreck and Big Saigon, it makes the Cape Baily area a rewarding day for a private boat out of Port Hacking. It suits Advanced divers with deep experience, ideally diving nitrox to get meaningful bottom time on a site that starts at 20 m.

Topics flagged by the stored research

These are questions prompted by the existing notes, not a verified or complete hazard assessment.

Current and timing
Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
Other water users
Ask about vessel activity, exclusion areas and the agreed surface arrangements.
Lines and obstructions
Discuss any known entanglement concerns and the suitability of the planned area.
Planned depth
Confirm the intended route and training requirements; the recorded maximum is not a target.
Water movement
Ask how swell and local exposure affect the proposed entry, exit and route.

Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
