Tiger Airways Australia can maintain its planes efficiently in Australia. After all, it's a waste to fly an A320 MEL-DRW-SIN, have it serviced in SIN, then send it back to MEL via DRW.
Which begs the question - Why is QF unable to maintain its aircraft efficiently in Australia?
If SQ has a problem with any of its aircraft, they just send it back to SIAEC down the taxiway who would have records of the aircraft from day 1. Now when TT has a problem with any of its aircraft, they just send it down the taxiway to John Holland.
How QF uses a myriad of suppliers from Singapore to KL to Manila, Avalon and Hong Kong is just mind boggling? A checks in LAX, C checks in Avalon and D checks in SIN.
I'm not an aircraft engineer, but how does QF maintain quality control over its maintenance when they're done by so many different suppliers all over the place? It's just like sending a sick patient to many doctors who have no records of his medical history - No matter how good the specialist is, isn't it a recipe for disaster? Or is aircraft maintenance simply such a striaghtfoward thing that you just follow the cards, get the LAME to sign off on it and send the aircraft out?
