Went into nillumbik cellars on my way past this arvo and looked out of interest at what they had in, they had beers from the following so if you go ahead they may be worth calling. This is in no way comprehensive and only based on me running in and grabbing a couple on nogne o pale ales, some sarsbeerilla stout from grand ridge and a couple of pints of the "old" recipe LC bright ale so I can pepsi challenge it with the new in a week or so. I think you could do an awesome and very varied case split from this shop however.

some belgians I can't remember, and all your standard aussie craft beers (little creatures, feral, james squire etc)
they really do have a great range and are locally owned, I'm not up for your buy as I shop at this place regularly just want to recommend them.
I have absolutely no affiliation other than being a happy customer.
