OT Australia/ New Zealand gaming

I will be doing a trip to australia/New Zealand this summer and I was
hoping some gamers in the area could let me know about any conventions or good
game stores to visit while I am in the area. My current schedule looks like
        6-8 May         Brisbane
        28 May- 3 June  Sydney
        8-11 June       Auckland
I believe I saw a mention of a convention in Brisbane while I am there, I hope
to drop by. it's always nice to see how other people game. thanks in advance
