Diving in Fleurieu Peninsula & Victor Harbor
The Fleurieu is where you go to see a leafy seadragon. Rapid Bay Jetty is the most reliable site anywhere, and Second Valley, the Bluff at Victor Harbor and Port Noarlunga are close behind. The ex-HMAS Hobart, a 133 m destroyer scuttled off Yankalilla in 2002, is the region's flagship boat dive, and the granite coves of Second Valley and Carrickalinga are easy shore dives.
THE LOCAL PLANNING BRIEF
Understand the options around Fleurieu Peninsula & Victor Harbor
South Australia’s regional directory includes Adelaide, peninsulas, islands and inland records. Use the access and environment information to distinguish these choices. A jetty, a coastal boat trip and a cave-related listing are different activities with different requirements; they should not share a single generic holiday plan.
What this regional directory records Counts describe published records, not bookable trips or confirmed open sites.
There are 35 published site records in Fleurieu Peninsula & Victor Harbor. The recorded categories include shore/rock platform (13), reef (5), island (4), jetty/pier (4). These categories reflect the database; they are not a ranking, a conditions report or an assessment of your suitability.
Use the Fleurieu Peninsula & Victor Harbor site cards to compare recorded access and depth, then open the individual pages for the map accuracy and source notes. Sites grouped in a region are not necessarily close enough to combine in one day.

Record your trip questions →Questions, answered
How do I choose a dive in Fleurieu Peninsula & Victor Harbor?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 35 published records are research options, not a list of trips available today. Match the plan to your training, recent experience and the operator’s current requirements.
When should I visit Fleurieu Peninsula & Victor Harbor for diving?
Choose dates with a provider who runs the activity you want, then discuss seasonal patterns, recent conditions and alternative itineraries. A generic best-month claim cannot establish the conditions at your exact site or guarantee a wildlife encounter.
Can I use these maps to enter or navigate a dive site?
No. Recorded and approximate map positions support orientation only. Confirm the exact access, permissions, meeting point and route with the responsible local provider or manager.
