Further to the comment from Ken
G-BNLG was registered as VH-NLH whilst with QF. (Never Leave Home)
ATC in LAX confused the a/c with a BA aircraft on one occasion. Soon after the colourful BA tail was repainted.
VH-NLH also caused a problem with BNE ATC whilst operating a SYD-HKG service. They confused the a/c with ZK-NCL a B767 that was operating a MEL-HKG service. This occurrence took place on 6 May 2001. Air Safety Investigation 200101996.
Also a number of different leased a/c operating for QF Freight.
