As a OW elite you can ask to get connected to premium desk when calling to normal QF res number, even that it's not possible to call directly to elite numbers without having QF status.

In my experience, changes to get good senior agent when calling QF Australian number are better after local business hours. Even normal calls seems to be routed sometimes to premium desk at that time. If calling late or nighttime more calls seems to be routed to nz that is not so competent than oz team.

And to keep on topic, I did another small date change with AY, frontline AY gold agent asked first from supervisor, didn't agreed to make the change first without the change fee as the change involved marketing carrier change which needed reissue. After I asked to check fare rules with rating they happily agreed with the change.

I really miss using AA RTW desk where I didn't needed always explain fare rules to frontline agents. But good thing with AY is not needing to wait in hold if matter is not urgent. They always call/e-mail/sms back after resolving issue.
