Is a 55 minute connection possible at HKG airport?

Which Australian city? I could only get CX to SIN then JQ to BNE.

Also it is not easy to get a CX business class flight and a QF economy flight on the one booking unless you pay for business class and get a downgrade on one leg.

On the last couple of days, I've seen HKG-SIN-PER in both directions and ex both. The latter never having been seen previously.

YES Mixed class would be two tickets.
