These are some favorite spots when we take the boat out from barwon heads.
For a quick easy dive try the boilers just outside the river, usually very fishy, have shoot/seen all the favorites here but make sure there is no big swell as it really whips up here quick with the change of tide.
We have marks on the gps all the way along from collendina to pt lonsdale, all we do is sound around for interesting reef around 20-30ft mark and jump in. Usually more forgiving on the swell here, you can see where it picks up on the surf beach the closer you head in. The closer you get to pt lonny though you have to be a bit careful of the current, it's not like queenscliffe but it can still keep you swimming hard.
Close in barwon bluff is nice reef too (careful of the MP of course) picked up many crays, Abs and shot a grotesque conger eel here. Once again this is a big surf break usually and it's very rare to get into the closer shallow reefs (around the 25ft mark). Pick your days!
Black Rock is full of awesome reef and a favorite snapper area, didn't get many crays here the past season as it was smashed by the local Pro. Like before we just sound for good looking reef at the right depth and jump in. There seems to be a healthy population of Wobby's around here too, some i think are on steroids.
My favorite location from BH is charlemont reef, which is offshore a bit but it comes right up to with in 8ft of the surface. You can't really miss it because you'll be wandering why the hell is there a surf break so far offshore. You need it to be dead flat to get the best of this area, you can encounter anything and everything out on this reef. It's get's smashed by the bubbles divers a fair bit though.
The last pic is of where I usually smash squid at qeenscliffe, I'm sure there's other fish here, but i'm usualy to distracted by them tasty bastards.
I'm not fussed about sharing locations, these are nothing new to anyone that has a boat.
All have been dived before.
Let me know if you want more.
