It did - and the you wouldn't believe what happened next.
We landed in Sydney and there were no regular gates available so we ended up in front of the air cargo shed, the captain had to get the ground team to move some equipment so as we could get into that spot, and then stairs arrived. Then we got on the bus and... the bus couldn't get a gear to engage. After completing three complete reboots of the bus they gave up on that one and we hopped off that bus on to another one to head to the terminal.
It seemed like every flight arrived into Sydney the same time that we did - huge queues at immigration waiting to get on to the e-passport machines, then the baggage hall was just a complete mess - totally overwhelmed by the sheer number of bags on the conveyers at once.
Biosecurity had all but given up I think - they didn't even look at my paper form to see what boxes I had ticked before waving me through.
