Just purchased instore at Bunnings Malaga (WA). Consists of 2x4.0Ah red batteries and 1x multi battery fast charger. No online links so I assume it's store specific edit: apparently on powerpass app nationwide so check in store!
At least 20 boxes left at the entrance to the tool shop when I purchased 30 minutes ago.
RRP if purchased separate is 2x$69 + $69.98 = $207.98 or if you can find the black style batteries 2x$48 + $69.98 = $165.98
