there have been sales known to happen, but I think QF has changed their MO slightly in recent times.
Back in November, for example, they had a "stealth" sale on domestic J fares valid for this period. It wasn't advertised it just showed up in the fare displays. IIRC they had 2 periods like this (the other one may have been in October). It may have even been an experiment to see the take up.
Never say never but I reckon it might be a little late to launch a close in sale for now, but you never know I guess.
