These non-stop flights aren't going to appeal to a single person outside of Sydney.  Why would anyone in Brisbane or Melbourne go via Sydney when they can go via Asia or the Middle East?  It just doesn't stack up by any measure.  Flying via Sydney is going to add 3 to 4 hours to yo...

Agree.  It wouldn't save you 2 hours anyway.  Changing in Hong Kong, Singapore or Dubai is going to be a lot quicker and less hassle than changing in Sydney.

Same here.  I'm in Brisbane and non-stop flights from Sydney have zero benefit or appeal, and will likely cost more.  I'll stick with a Hong Kong or Singapore stopover over Perth too.

You've not been to the Cathay Pacific lounge in Hong Kong then :).  Once you've experienced that you'll never go "back" to a Qantas lounge.  Even flying with Qantas business I would always choose the Cathay lounge on the stopover.

No screens = not business class.  Come on Jetstar, even United Airlines economy has screens for goodness sakes.
