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.

Let the exact outing shape your plans. A pier visit, a bay boat trip and a more exposed coastal outing can all appear in a Victorian search, but they ask different questions of your transport, equipment and support.
Use the region to browse, then work from the confirmed departure or meeting location. Ask where fitting and briefings happen and whether equipment collection involves another stop. If you are travelling around the bay, check the actual journey rather than judging distance from the map alone. Keep the return arrangements in view when booking the rest of the day.
Some historical site records contain tidal shorthand or precise timing notes. Those notes need context and current local assessment; they are not a timetable to follow from an article. Ask the provider how the proposed route and timing are chosen. Make sure everybody in the group understands the actual environment and what experience is expected before treating the trip as settled.
Tell the provider about the exposure protection and equipment you have used recently, then discuss the system for this outing. Include fitting, surface comfort and equipment returns in the plan. If you hope to combine a course with the visit, ask how its sessions work alongside the proposed trip. An unfamiliar equipment setup deserves an introduction, not just a mention on the packing list.

THE LOCAL PLANNING BRIEF
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?
There are 58 published site records in Mornington Peninsula. The recorded categories include reef (23), shore/rock platform (15), jetty/pier (12), muck/sand (4). These categories reflect the database; they are not a ranking, a conditions report or an assessment of your suitability.
Use the Mornington Peninsula 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.
