Diving in Mornington Peninsula
The Mornington Peninsula's piers are among the best macro dives in the world. Blairgowrie, Rye, Portsea and Flinders piers have weedy seadragons, giant cuttlefish, spider crab aggregations in May and June, pyjama squid, frogfish and seahorses in 4–8 m of water, and are dived by night as much as by day. The back beaches (Sorrento, Portsea, Cape Schanck) have caves, ledges and bull rays on the rare flat days.

THE LOCAL PLANNING BRIEF
Understand the options around Mornington Peninsula
Compare the pier or departure, not just the peninsula
The Mornington Peninsula is a practical browsing label, but the individual sites still differ in access and exposure. Read each record’s location and map notes, then confirm the meeting point and any current pier restrictions. If taking a course, ask whether all training sessions meet in the same place and what equipment arrangements apply. Leave time for the complete trip from your accommodation rather than treating the map pin as the only travel task.
One useful question: Are the meeting point, entry area and parking arrangements currently the same as those in the older site description?

Record your trip questions →Questions, answered
How do I choose a dive in Mornington Peninsula?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 58 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 Mornington Peninsula 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.
