Chinese carriers finally ramping up as well as new entrants like TK and higher capacity from others like CX and SQ will make the overall market share by QF lower (and QF can't put more capacity in anytime soon bar minor adds like DRW-SIN later this year).
However the market share numbers doesn't have to mean less people are flying QF. For that, you'd have to look overall raw numbers flying QFi, which would take into account small capacity increases related to routes being geared back to ore pandemic levels, 3 extra 789 shells added during the last year, and new routes (eg SYD-AKL-JFK, finally resuming SYD-SFO).
The other potential factor that comes to mind is that outbound demand may have slowed due to cost of living pressures etc, but potentially iffset by a return of (some) tourist demand inbound post pandemic. Nowhere bear where it was specially from China of course, but likely improved Y-O-Y.
