Seems this got missed on Ozbargain. You have about 40 minutes left. (I got an email from Bundle Stars about this).
I just got these two for about $4AUD

Has Men of War, IL2 1946, Commandos Collection and more.

A bunch of other "Heroes" bundles, just check it out.
According to the Steam prices, that is a $140 USD savings for the two.
All keys redeemed fine on Steam.
