I say yes, but I base that on giving the user freedom of choice, not pandering to people who want the QR passes back.
Significant discounts should be offered for buying periodicals as they represent money up-front for the system, and give certainty to the user. Likewise, discounts should be offered for pre-loading credit by auto-top up or Bpay (which you can use in Perth and Canberra, but not here).
I would favour bringing back weeklies, monthlies, quarterly, half-yearly and yearly passes that can be loaded onto a go card for a select number of zones, with a top up fare payable for travelling outside them.
Capping should also be implemented and available for the 'floating' balance on the card - should apply for daily travel and then gradually apply for the above periods based on calendar months.
My concerns about what the Minister has said so far about the 2 products specifically in question are (a) as others have said, it sounds suspiciously like a fait accompli, and (b) it is entirely political and for the benefit of noisy long-distance commuters, not for the system at large.
