As per topic, I was done with my ANZ FF Black and called to cancel. Was offered 20k Qantas points extra in the next 90 days to simply hold on to the card, no minimum spend.
I realise if I was a die-hard churner I would jump ship to reset the clock but to me this is easier and I'm lazy.
No idea if this will be applied across the board or what, I get the impression they are trying to minimise churning with this offering and I guess it's worked for me.
For reference my first statement was in April this year, annual fee isn't due til next year.
