This is probably waaaayyyy to late, but... I just moved to Brisbane and am looking for games. Maybe at one of the games stores on a Saturday "Board Games/General Games" day.
No idea if anyone plays. I am getting games in with one mate and we only have the first two sets as it wasn't worth investing because we could not find a player base.
You could try Good Games Spring Hill, GUF in Fortitude Valley and Critical Mass at Chermside which is a boardgaming group which are on the forums here or Facebook.
