As posted below, VH-SYO passed through Longreach Airport the previous weekend and since then, the BAe-146 has been noted flying in Far North Queensland - up as far as Horn Island.
At the time of writing, it appears that VH-SYO is staying on Hamo for at least the night.
UPDATE! On Monday 23 May, VH-SYO departed Hamilton Island Airport for Brisbane as 'SFZ612' / "Skyforce 612". It then flew to Bankstown as 'SFZ9009' / "Skyforce 9009".
