I think I will do the same with my near-identical issue (Qantas refusing to accept validity of a Finnair codeshare flight) so I will give them one more chance and tell them that I will address it with the ACA after thatAs an update, QF acknowledges the integrity of the ticket and Oneworld Explorer Fare (which means that charter flights cannot be included in these tickets and all flights are eligible to earn points and status credits by OW airlines) BUT "computer says no", AY3885 is considered a charter so cough* off and don't bother arguing any longer.
I have lodged a complaint with the Airline Customer Advocate, not having much hope of getting the points and status credits, but I won't be giving up for now
