Olympus OM-D E-M10 MkII with 14-42mm kit lens. This is a older (2015 release) micro four thirds camera that's been superceded by the MkIII, however this is a really good price.
Can combine with the Shopback cashback that expires end of today. Not sure if the spend works off the pre-discount and/or pre-GST amount. https://www.ozbargain.com.au/node/480089
I've picked one up with the Olympus 45mm f1.8 lens ($299->$239.2) for a total of:
$439.2 + $239.2 - $60 shopback cashback = $618.40
Aus stock and warranty.
Available in black or black/silver.
Also Twin lens kit is $749->$599.2 then combine with $60 shopback cashback
