Diamond Bay, named after the Diamond jubilee of Queen Victoria, is a popular family beach of Sorrento on the back beaches of the Mornington Peninsula surrounded by impressive sandstone cliffs. Diamond Bay faces south-west into Bass Strait.
It has many rock ledges and overhangs, kelp beds, reefs and small walls. In these is a variety of life including the odd crayfish! You'll also find old wives, boarfish, abalone, and schooling fish.
Another thing to be mindful is of the visibility, it can change quite quickly with the swell as it's a sandy bottom. It is advisable to go with someone who has been before also to come to the surface to check conditions and for navigational purposes every once in a while.
Now you can walk straight in from the stairs though you'll probably find more and avoid just looking at sand if you head over to the side and swim towards either point. Once you get about halfway along the bay is where the dive really starts and also begins to deepen. You'll find some bommies and kelp forest just before the point on the right-hand side — the direction usually taken.
Diamond Bay is a spectacular dive site but not often diveable. This site is more protected than other Mornington Peninsula Back Beach dive sites so when others are too rough this site can be okay.
Awesome looking landscape with lots of kelp, gullies, interesting rock formations and overhangs due to the surf pounding at the rocks. Not much macro life but you can find lots of crayfish and abalone (so bring a measuring device if you want to catch some), wrasse, sharks including catsharks and Port Jacksons and lots of leatherjackets.
Viz can be bad close to shore but clears up the further out you go if the weather is good. Weather can turn bad quickly so it can be helpful to check on conditions now and again throughout the dive. There are often rock fishermen on the east side of the bay on the cliff face or shallow rock ledge on the west so beware of their fishing lines.
If you're lucky enough to dive here on the right day everyone will be jealous. There aren't many facilities here so make sure you have everything you need including dive flag, knife, SMB and possibly a catch bag!
