New here as well, just moved to the Central Coast from Sydney, expecting a baby in Feb. Luckily my partner is American so I am planning on sending all the US stuff I buy to his mom, then she can bring it over when she visits! I have also bought a lot of WAHM stuff of hyenacart. I always ask if they ship to Oz and haven't had a no yet!
I did have a problem buying a BG4 and some feeding stuff for my sister in Belgium from a US site. I didn't read the shipping info and the shipping was $45, almost as much as
the items in the first place....
