We're sitting in the Melbourne Qantas Lounge, courtesy of two fellow Flyer Talkers, Dean and Karen, who hosted us in. What a lovely facility it is!
It's on the other side of the airport from our Virgin (DJ) flight, and we'll have to go through security again, but what a sensible breeze it is when traveling domestically. One needs neither a boarding pass nor I.D. You can keep your shoes on. You can carry liquids through. What looks like a long lineup turns out to take a very few minutes.
The Australians are a very sensible people, compared to, ah, some others we've experienced.
