Thanks everyoe for the replies!

The SYD-SIN/BKK on BA is OK, but I do a lot of flying to other Asian cities.

That's very interesting about signing up for AA as a Canadian member. How would I get around the initial address problems? Actually...the company I work for has an office in Canada...They could just send the initial welcome pack over via internal mail!!

But if I sign up as a Canadian, then change over to an Australian address, would that mean I would then be subject to the Australian rules? Obviously I couldn't keep the Canadian address for ever

That actually seems do-able. I am getting quite sick of SQ - I seem to spend half my life transiting at Changi. It'd be nice to be able to fly CX & BA for a change (and maybe QF, although I don't like that 70%). And I would deff'y do enough flying to qualify for the platinum challenge.
