Have transfered many times between domestic an international in Sydney from Melbourne flights
I would NEVER allow less than 1.5 hours
I would highly recomend you change your flight from Brisbane to an earlier flight
Although QF and other airlines will book 1 hour transfers in my view this is unrealistic anywhere - even in SIN which is the best airport in the world. I should say we did have a 50 miniute transafer recently in LA - QF - JFK->LAX - this first flight was 10 mins late (astually left 1 hour late but was a very quick flight) - but we were up the front of the plane which made it easier. We made the Melb connection but onlyjust (and so did our luggage surprisingly !!!) although the flight from LAX ->MEL left 20 mins late
