Righto.. got a question considering you guys are talking dry suits.... what thickness wet suits are you using in Vic? We only have ones for tropical use (3mm) but as my husband comes from Melbourne, we are thinking we should look at another wetty for our return back to Oz...particularly now that I have seen those pics and wanna get out in that there water!
For summer (about 15-20C) and start of autumn I wore a 7mm semi dry with 5mm gloves/boats (no hood until it dropped to 17C).
For end of autumn and start of winter (12-15C) I wore 7mm semi dry with 5mm gloves/boots, with 1mm neoprene socks and 2.5mm hooded vest.
Now it has reached 11C I am adding a 0.5m full neoprene wetsuit underneath all my other stuff - just got it so haven't tried it out to see how warm it is yet, will see this weekend!
My buddy wears the same as me though I have noticed these days we are often the only two on boats that are in wetsuits, unless there is an OW course on.
I do long dives (usually 40min x 1 and 60min x 2 for each dive day) so by the end I am usually freezing (especially as we go real slow for photos!) but I have coped ok so far. 11C is the coldest it gets off boats (and a bit warmer when you go outside the Heads) I have heard, but on shore dives it can get down to 8C apparently.
Anyway, so what you need will depend on if you just want to dive in summer or if you want to dive all year around. If you are going to dive in winter, if you can afford a drysuit (I can't, hence the many layers I wear ) I would highly recommend that for winter. If it is just summer, a 5mm should be fine unless you really feel the cold, then get a 7mm. Actually 7mm is probably better as it will last you longer in the season than a 5mm. Hope that helps!
