Shipping is actually more from Oz to the US then back the other way...container ocean freight is abit higher, as are port charges (there is a US$600 charge just for when they arrive here at the LA/Long Beach port)
It's not alot more, but abit.. I personally get AU$3500 to go from LA to Melbourne and US$3500 to go the other way..so just 10% - 15% (depending on the dollar) difference in cost..
I just sent another 5 containers to Oz (do about 20ish a year) and probably will be doing another one back this direction when I head over as normal for Feb/March..
