Look for operators around Whyalla →South Australia
Every winter tens of thousands of giant Australian cuttlefish gather on the rocky reef between Point Lowly and Stony Point to breed, in 2–6 m of water a few metres from the shore. It is the only mass aggregation of its kind in the world and one of the great wildlife dives anywhere. The Whyalla jetties and the Point Lowly reefs are worthwhile the rest of the year.

The table above contains the same depth values. Depth alone cannot establish suitability, and records may require correction. Source: the linked site records.
A jetty, a boat outing, a seasonal wildlife visit and an inland training objective are different starting points. Name the experience first, then use the records to explore its practical setting.
Do not assume that two experiences grouped within a state are easy to combine in one day. Write down the town, meeting point and time commitment for each. For a mixed group, ask which activities actually accommodate divers and non-divers together. A famous animal or landmark may bring you to a region, but the booking still needs to describe what each person will do.
A site category is a starting point for learning more. In particular, an inland or cave-related record does not make an outing an ordinary open-water dive. Discuss access permissions, the intended environment and appropriate qualifications with a relevant provider. Choose training to suit the activity rather than trying to make a planned holiday fit whatever qualification you already hold.
If one wildlife event is the main attraction, research its current visitor information and the exact activity being offered. Keep another worthwhile part of the visit in your plans. Arrange equipment and support before treating dates as final, and ask what happens if the intended outing changes. A recent observation and a broad seasonal pattern answer different questions.

Record your trip questions →Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 17 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.
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.
