Depending on the exchange rate you may be better off to withdraw in the UK and exchange for cash when you get here.
Travellers cheques are safer but to me, that safety is discounted by the fact that you have to carry your passport with you everywhere to use them as most places in Oz will want to see it when you sign your cheque before they will accept it. Good way to lose your passport but that's just my opinion.
Up to you of course but I would use cash and my credit card if I were you. Facillities for both are readily available.
Keep an eye on the exchange rate the week before you come. You should do well - better than I did when I exchanged Aust currency for pounds in 2006 - I nearly cried.
It was nice of them to reply and thanks for your help,wasn't it.
