To a degree I think you just have to ignore WA, things will change only when interested parties indicate their concerns/problems to MM and he finally decides to "pivot", draw your own timeline.
Some of that maybe - second hand - but a friend from east coast wanted some travel, initially booked Porn* early April to Bali, now early Feb and required covid insurance for $80.00 available on arrival, imagine have to be supported/underwritten by the Indonesian government.
As with all insurance "read the fine print" but believe that's what's available.
Along with the WA mining companies staff shortages there'd be more than a few locals wondering why east coast can fly to Bali - but WA can't.
