I'm curious to know what happens in these TRA sectors - do the all the conflict alarms get turned off, screens switch off etc? I'd be surprised if there is no-one looking at them - but just not enough (qualified) people to provide the service. The airport that most recently started all of this - Darwin - clearly had some staff on duty through the nights - just not enough.
So for this incident, I wonder if it is possible someone noticed the impending problem - or an alarm went off - and that caused the instruction to go out - even though they weren't technically controlling the airspace?
So many questions.

AFAIK, the airspace at the time wasn't a TRA and therefore TIBA procedures were
not applicable. I'm not even sure that the airspace was subject to an Operational Restriction NOTAM. But the sector grouping has had numerous TIBA/TRA and Operational Restrictions NOTAM issued over a long period of time so I think it would be fair to say that it is a Group that has been doing it pretty tough for a long period of time (too long). I feel for the Individual ATC and the Group as a whole.
Thread drift, but the question about alarms is important, especially when the APP/DEP function isn't staffed and whether other Units assuming responsibility e.g. Cairns Tower, Mackay Tower or an enroute group has the same alarms, different alarms or no alarms.
