Metro man,
Qantas needed the assets elsewhere on the network.
IE Virgin put A330s on the domestic transcontinental routes, so QF poached them all to counter it.
Id expect to see a renewed push in Perth with the arrival of more longer range airframes.
No feed? Perth has 3 million cashed up bogans living there. Not to mention the feed from say Adelaide and Darwin or any other city if there was a direct flight to Europe.
It would very very popular.
When was the last time you visited Perth? Must have been in the 80s.
