I thought the big Q outsourced it's maintenance to Asia?
qantas has heavy maintenance bases at brisbane airport (767s and a330s), melbourne airport (737s) and avalon (747s), and sydney does the A checks (1 - 3 days) that are required every 1000hours of flying or something like that, i forgot
the brisbane facility and the avalon facility outsource aircraft to asian providers that can't be slotted into a hangar in australia when its maintenance is due. theres been quite a few go overseas this year and last (i got to go and oversee one of them in hong kong for 2 months which was cool).
so basically the new management thats come in since dixon was booted has stated that all maintenance is done on shore except for when theres an extra need at odd times in the year as aircraft run out of hours/time before they are due for a maintenance check.
