Some Virgin flights seem to be showing up randomly on FlightScout to Hong Kong, at low prices. Take a hunt around as they have only found a few, but it could be indicate of more around those dates.
OOL/CBR/SYD/ADL from $489/ $501/ $502/ $514
Virgin flights can earn Velocity Points.
Seems to be different dates / limited dates compared to the deals from this week of last month.
EDIT: Now Qantas has a sale too: https://www.ozbargain.com.au/node/409325
