In Victoria you can get an interest free loan from Clink to buy whitegoods. I don't see any reason why it wouldn't be available anywhere else. They direct debit from your payment. I think you can get up to $1000 and have a year to pay it back.

DO look out for reconditioned fridges. Places that do it are likely to give pretty good warranties. In fact I've only bought my first brand new fridge about 2 years ago because reco ones were far cheaper and just as good.

Don't forget about a vacuum cleaner - you just can't live without one!
