Hi Lil
It's a big question you are asking.
You might want to have a look through the old posts in this part of the forum (South Australia).Most answers and discussion are still good and current info.
Don't forget that hubby who is a Joiner will have to get a license to work here have a look at
OCBA - Licensing
A lot of people don't realise they have to have licences and I'm sure agents are not telling their clients!
Good luck.
