Been advertised for about a week now at all of my local HJ stores in Newcastle (Jesmond, Kotara, Glendale, Broadmeadow etc.).
Could be state wide but haven't seen it posted on here yet so am assuming it is Newcastle based stores only, leave any other confirmed stores in comments below. There is no online advertising of it also and is only displayed next to the drive thru speaker or in stores with no expiry.
Enjoy
Hungry Jacks is probably trying to keep up with KFC's $1 Chips campaign
The only difference is that HJ's chips are better
Hungry Jacks FTW
