I was onboard the aircraft...
According to the captain, the "staff shortages" were ATC-based... holding was going to be an hour or so, and we did not have sufficient fuel. So a nice 90 degree turn to the right and we headed for BNE...
Felt sorry for those who were supposed to be catching a connecting flight to BNE, they were unable to disembark (apparently the crew tried everything sort of going to jail to get them off the aircraft), and by the time we got to SYD, the curfew had kicked in, so they were staying overnight...
As the captain pointed out, the only glimmer of light in this whole saga was the fact that a flight due in to SYD had been diverted to Canberra... it too had passengers on board who were supposed to be catching connecting flights... to Canberra... including a bunch of pollies... like the Minister of Transport!!
ps. Don't try to catch a taxi from SYD international terminal after curfew... 45 minute wait... and I was about 8th in the queue!

Luckily I got Michael Schumacher as a driver... so it only took about 15 minutes to get into the city!
