i must admit the local bottlo in ringwood (in the 'burnt bridge shops' on maroondah hwy) has a bloody good range of beers. standard megaswill, standard faux micro (ie full coopers and JS range), some aussie micros (mad abbot in Qld, hargreaves, etc) and then a good range of imported such a TTL, Unibroue Trois Pistoles etc. the prices are a little higher than you could get at a Dan's or similar but they are local so its good.
edit: just read the OP properly. obviously ignore my suggestion unless your staying out in the eastern burbs. the above reccomendations will see you through your trip.
