When it comes to Qantas, most card issuers offer the ability to opt-in for earning Qantas points directly in lieu of credit card rewards points. For this reason, Qantas points can really only be earned using hotel rewards programs and since there are no co-branded hotel credit cards in Australia, this will not help much in terms of earning lots of points.
If you're really looking to earn Qantas points, you'll want to pick one of the 30+ credit cards they offer.
