@Gracchus It's too late now, and would be risky to do so, but I would have filed a complaint as soon as the demand to run the proprietary malware came in with whatever the rent management body is that the realestate agent is demanding that you purchase x brands of tracking device to install questionable software merely to continue to pay rent, when bpay worked fine for years.

Unfortunately, there's not much you can do now unless there's some legal requirement that doesn't allow the application of arbitrary fees on top of the agreed rent amount - which would force them to offer you BPAY again, or whatever other payment method that doesn't allow have scam fees, but you'd still end up on the list of non-subservient renters.

>is this even legal?
From my limited knowledge about Australia's downright ridiculous financial requirements (i.e. businesses aren't required to accept the legal tender of cash if they just put up a sign saying that they don't accept cash), it would be illegal to demand changing from BPAY to "Ailo" during the rent term, but it's likely not illegal to demand the usage on "Ailo" on renewal of the rent period.
