Just be careful is all I'm suggesting...

I understand but legitimately a lot of it has been private, wife's car new 328i, substantial renos at home, rates and insurances on investment properties, lots of accomodation & restaurants, regular monthly PAYG tax on personal income so I am am holding my breath, if they can me I still have the Jetstar MCARD and Signature Citibank but would rather use the WWEDR card.
Ironically I asked for a limit increase and they said NO even though $ 20/$25K per month goes through the card
Hence my original comment of $10k to $15k pure ATO spend per month "should" be OK
(@$15k per month that's still ~180,000 each and every year with this "Personal" card, yes you may be able to get more than that, but the question is for how long...? YMMV but I think this card is worth keeping since its $89 p.a for a 1:1 MC, so I don't "abuse" this card)
