Hi Dr Ralph, my input.
Re: Opting in, I don't believe you need to contact CBA. When you login to your account and navigate your way to the rewards page and then follow the Redeem, then Travel menu options, You will be presented with an option transferring to an airline other than Qantas and an option to transfer to QFF. I've transferred to VFF a couple of times no problem. For the QFF, there is an "Opt In" button. I clicked it to see what would happen but was asked for my QFF number and to accept the terms, I didn't not go further to avoid the $30 fee, but assume that is all that is needed.

Re: Dollar spent, actually CBA are quite good at this, as I'm hanging onto this card for the 12 month to get the other bonus points (per my offer detailed above) and actively watch my spend to spend no more than is necessary than the 2.5k per month and I'm OK with that as earn rate for VFF is quite good when transferring at bonus periods. Anyhow, I've included a grab which shows that they detail how much has been spent in the statement period (note it does not include pending transactions). My experience has found that they show the next statement period end date a couple of weeks prior to it occurring - right now it is not displayed but it does come up, but it is not hard to work out when that would be given the previous months (granted first month maybe not totally clear).
