"Why would China want Australia involved if it didn't involve higher gains for them and more losses for us?"
Because we're a developed country, part of Asia, and a significant trading partner of China.

Dunno about that, les. I supported Abbott's decision to send troops to fight Isis, as Obama wished, but you do realise our SAS have been sitting in UAE for 5 weeks plus because Iraq wouldnt let them in? You dont think Tony or Julie should have done their homework BEFORE they sent our troops over? I voted for Abbott, but he's doing a few kneejerks lately....
