*LAX

Not all of them, ie. on the 2nd july you can get a MEL-LAZ flight in business. 

It s possiable to get business class on the Australia to US leg, but they are hard to come by. 

This sounds like a great deal!!! just wondering, can you use the miles on any Qantas flights or just those to the US?

No, Qantas international also does not serve Canberra, Darwin and Hobart!!
