There is a recent shot on Airliners.net of B-HIH (CX 742SF) taken on 11/10/08.

If you look in the background there is a QF B744 (RR powered) undergoing a check just outside the hangars.
QF reckons they do 90% of their heavy checks in Australia but there seems to be an increasing amount of aircraft showing up in Asia for heavy maintenance...HKG, SIN, MNL and old SZB.
