The reason AMP are included will be precisely because they do earn QF points, I suspect - of course I don't know the details either, but maybe it'll be something like "earn x points via this route" to get the status credits, and I also presume it'll be collectively, amongst all the partners in each group. Could be wrong, of course!
The earning of QF points requires you to hold a balance in there, you essentially forego a decent interest rate elsewhere to earn QF points instead - their rate is 1x QF point for every $10 held over the month. $10 at an annual 5.5% interest rate (using ING as a very good example) works out to be somewhere in the region of ~4.5c per month interest for each $10 - so you're buying QF points for ~4.5c each, which is a terrible deal.
By all means have the account, I do, but I don't recommend holding any sizeable amount of money in there in order to accrue QF points. If anything, throw whatever you need in there to access overseas before you go, use as required, you'll maybe earn an amount of QF points on that (depending on amount and how long it's there), which is a small bonus, the main prize being the zero fees. Not financial advice, but I'd (unofficially) recommend having more than one account/card that has no fees, so why not open this and Macquarie (and any others you might want), just the be safe! Never rely on just one, either way, even if the Plan B has fees, it's better than being stranded without access to cash.
