Eh? If travelling in oneworld first class, you can access any oneworld first class lounge in the same terminal (just like if you are travelling oneworld business class you can access any oneworld business class lounge in the same terminal).
If travelling BA First ex-HKG, you have access to CX The Wing, The Pier, The Cabin and/or The Bridge. There are F sections to The Wing and The Pier, although the latter is currently closed for refurbishment.
There is also no combined Qantas/BA lounge - QF operate The Qantas Hong Kong Lounge.
