Jasedee,
It ceratinly looks like the UAD-1 is the right choice for you.
I don't know what it is like importing hardware into Australia but if I were you I would investigate getting one imported from the States. There is an online shop at
http://www.jrrshop.com.
They have UAD's at a very good price and if you join the UAD-1 forum at
http://www.chrismilne.com/uadforums/default.asp and enter the word "forum" into the discount section on the JRR webshop you will get an automatic discount of 10% - which would probably pay for the shipping!
You won't be disappointed with "Uncle E"'s service - he pulls all the stops for his customers. I have never bought from him but when I get my 2nd UAD-1 I will be getting it shipped over by "Uncle E".
All the best,
Martyn
