Got a chunky personal ATO bill to pay and can't pay through a business, so any services requiring an ABN are out.
From the reading of the thread, it looks like AMEX via Sniip might be the best bet but from my calcs it seems marginal...
~2c/pp transferring into AMEX partners or ~2.4c/pp transferring to MB partners (waiting for a 50% transfer bonus out of AMEX). For a lot of points currencies, that's getting close to the rate you can just buy them when they offer purchase bonuses
.
Anything I'm missing?
