Not sure when the special finishes. Good price, not the cheapest but pretty close.
However combining it with the recently purchased Coles Myer Gift Cards (https://www.ozbargain.com.au/node/322843) it brings the price down to $4.06 with 40% off (assuming you got the $50 GC with $20 credit from AMEX) which I think may be the cheapest but happy to be corrected otherwise; nevertheless pretty good price especially at your local supermarket.
Pretty worthy of stocking up hence my post.
Don't forget to collect those Flybuy points!
Enjoy.
Nowhere near the acceptable quality grain any rice-snob would even lay eyes on (medium grain with a high % of broken grains), but ok for the uninitiated masses I suppose given the price.
