A good price for some Quality Batteries.
Of particular mention are the DIN44MF for $160 (420CCA) and the DIN53ZLMF for $180 (500CCA) that Mitre 10 also carry stock of which could net you a price beat price of $136 for the DIN44MF or $153 for the DIN53ZLMF they can do a price beat over the phone for click and collect or wait till Level 2 restrictions mean you can go into store on Thursday.
Mitre 10 also stock some of the other Century Battery Models but need to order them in so not sure how that works for Price Matching.
Or if you are after one of the other Models I would consider the Supercheap Pricing very good anyway. I needed a new Battery a couple of weeks ago and got some trade prices from Wholesalers that were not as good as the Supercheap Sale Price, (I purchased a DIN66 AGM in their recent 25% off Sitewide Sale)
