QF11 VH-OQC Returning
 

QF11 is returning to Sydney

I say a technical issue going by this tweet

The aircraft tracked via KAMPI and TESAT

Based on the ACARS reports, looks like it may have been a problem with the APU and/or Engine No. 2.

MISC OVERWEIGHT LDG - This indication was reported during the approach in the QF32 accident - presumably the aircraft being over the Max Landing Weight (full fuel load from departure).

AIR APU BLEED LEAK - APU or Engine bleed leaks can lead to fumes in the cockpit or cabin. The APU can supply bleed air up to 22,500ft in flight.

VALVE 1-HP BLEED - At low engine thrust settings, the pressure of the IP stage is not sufficiently high and bleed air is provided by the High Pressure (HP) stage of the compressor, via the HP valve.
