westpac
i prefer this card because:
1) inertia (i was an ex Ansett GR card westpac card customer), I also keep most of my day to day banking with westpac and really like their internet banking service (strips the competitors to pieces!)
2) I can earn miles on NZ and QF, and it's a visa (there aren't many visa/mastercards? in the market which let you do this)
3) You can also transfer to MH 1 to 1 as well
4) reasonable bonus offers (though not as good as others - flight centre $3 = 4 points and flight centre will beat the best price you get)
5) gold card is a true, fully fledged "overseas" travel insurance service
6) gold card has 90 day loss of purchase insurance
7) gold card has double warranty insurance
Over $100 a year, but worth it just for the travel insurance on it's own as I go overseas at least a dozen times a year.
