Booked my flight from Sydney to Singapore on www.qantas.com.au using points, normally cost 30000 points, now 24000 (20% off), works on other destinations as well IIRC. You still need to pay the tax and charges which you need to pay regardless,
$256 in the case of Syd to Singapore.
Note: I only tried the Classic Award flights booking only, not the Any Seat award.

Ends tomorrow
I forgot to mention that I booked my flight for the peak Dec Xmas period, 15-31 DEC which cost you around $950ish if you book now.
So this is a saving of approx $700 when I spent my 24000 points.
good deal too bad the taxes are humongous on qantas
