Had the same e-mail. Vic Brew are organizing a bulk shipment and bottles need to be with a committee member before Monday 5th. I'm hoping for a response to my return e-mail so that I don't have to spend the weekend randomly wandering the city, clutching my entries, asking people if they're a member of the VicBrew committee. Might be a good job its a long weekend.
If you can't get the bottles to the VicBrew committee, the AABC entry form states that entries are due at CraftBrewer on Friday 2nd October and I assume that you'll have to cover postage personally although the e-mail did say that VicBrew will cover the entry fee (just note it on the form)
