All games for ps3 and xbox360 are $5. Does not apply to ps4 or xbox 1 games.
Best bet and best deal is the gt6 for ps3 which had about 50 copies on the shelf. They're stickered at $88 and scan at $77 but one of the sales guys there told me about the $5 price and the checkout chick reduced it with no questions, so I guess it's legit. Receipt attached anyway on http://files.ozbargain.com.au/upload/20542/21813/13958813919…
Also and possibly a separate deal, SanDisk cruzer 8gb for $3, 16gb for $9. The 8gb will probably be gone by the time you arrive, but plenty of 16gb ones.
Lots of other clear out stuff, too many to list. I'm supposed to be working!
Last day is 31 March when they shut for good.
<ot>And while you're there, check out the snowgum clearance. </ot>
Edit: the receipt as some of you have noticed is folded. This was so I could get the gt6 line item and the Harvey Norman header in the same shot. I bought 3 copies of gt6 out of a total of 8 games, so no my middle name isn't Broden. And all 3 copies of gt6 are spoken for so please stop pm-ing me to sell them to you.
Also see this comment on other ozbargainers' experience. Apparently minimum 10 games is required from Harvey Norman.

No wonder they are going out of business… ;)
