Just bought this from my local JB HiFi using a price match. They texted me a link to do the purchase and I was able to apply my $10 JB Perks voucher, so paid $637. Previous best priced Ozbargain deal on this was $699. Note that this is the "5i" (i5 processor), not the older "5" (i3 processor) version.
Update - Have marked as Expired. OW Price is now $897. Same as Amazon. Arrow Computers has it for $699 (plus $30 del / free pickup if you're in WA) so there is possibly the opportunity for an OW price beat to $665/ $693. However, it does indicate packaging damage in the fine print - so OW may not do a price beat.
These are really really good machines, my wife has one and it's very powerful. It feels crazy fast and battery life is good too. The speakers are great, the screen is good but could be a bit brighter, but she doesn't seem to mind.
Highly recommend this machine.
