I did a mirror image of what you did, went to the news agents to buy some Select AFL cards and saw they had same Panini NBA Cards and grabbed half a dozen packs as well. Pulled Dante Exum and Danny Green Hot Signatures cards. Looks like they are based on the Panini NBA Hoops Cards and feature inserts like Courtside, High Honors, End 2 End, Floor Generals and a bunch load more, but with slight design variations, the backs of the base cards are pretty well identical design to the Panini NBA Hoops Cards. This is the stuff I pulled from the packs I picked up. (I took a photo of the actual packet as well in case anyone spots them in their local news agents)
