mosschops - i don't want to offend, but I wouldn't want live in Laverton or Point Cook - there is a huge sewage plant there and if the wind blows the wrong way .... ugghhhhh (lived at Point Cook for a time, so I know) - Williamstown is north from these places, and much nicer - although, my vote is still for Ocean's Grove ....
As for Bankstown, Quakers Hill and nr Liverpool - my cousins lived near there and it was VERY VERY ROUGH. If you thinking of Sydney, go north up the coast, or south down the coast, but not inland.
Someone mentioned Townsville - nice in the dry, nasty in the wet season (Dec, Jan, Feb, and maybe March) ... very humid ... all you want to do is lie on the tiled floor and drink copeous amounts of water .... also, watch out on the beach for there is a "stinger" season - jellyfish, which are poisonous - you can only swim at certain times of the year
