Seeing a lot of availability for QF 1 and QF9 DXB to LHR on KVS, however it's never bookable by any telephone agent. Specifically Jan 1 and 2 as of this post.

I'm seeing it in both the AU-QFA-SP1 and BA-Oneworld award/upgrades search.

I'm thinking that there's some sort of restriction on booking this without transiting Australia but is there anywhere in the software that would tell me this on this flight and any other potential flights?

Thank you
