Where in melbourne will you be living? There's lots of shops around, there's guaranteed to be a few close no matter where you settle. Depending on what you want to keep some are better than others. Do a bit of googling but to get you starteD here's a few, forgeneral stuff I would recommend Coburg aquarium or V&L aquarium (my usual day to day shop) also upmarket aquarium at the victoria market which as a new arrival you will probably end up checking out anyway, bigger fish geelong family pet and aquarium or big fish aquarium, for discus OAFI, and for aquascaping and dwarf cichlids subscape aquarium and new life aquatics in Richmond. Richmond is a Vietnamese area, lots of tasty cheap food on the same street too!I’m actually moving down to good ol’ Melbourne in the near future... so if you got any good shops worth hitting up, let me know incase i get the itch to set something up quicker than expected lol...
Hopefully you will enjoy living here , let me know if you need any local advice when you get here, will be happy to help.
