Toyworld Sunbury has POTP stuff in. All size classes form prime master to leader.

As of 10 minutes to closing time they had

Legends: 2x Skrapnel, 2x Windcharger, 1x Slash, 1x Beachomber. (the other Slash and Beachcomber came home with me) $19.99 each
Deluxe: 2x Jazz, 2x Slug, 2x Dreadwind, 2x Swoop. $36.99 each!! That’s MORE than they charged for TLK Deluxes!
Voyagers: 1x Grimlock, 1x Starscream. I believe they were $50 each
Leaders: 1x Rodimus Prime. Think it was like $90 or something
Didn’t take a very good look at the prime masters so I don’t remember what’s there or the price, but the pegs were pretty packed with them so I assume none have been taken yet.

If you go there looking for them, they aren’t with the rest of the transformers. That said, you can’t miss them, they are literally right there at the end of the nearest shelf as you walk in.

Bit disappointed I walked out of there with only 2 legends. But I wasn’t looking to buy anything bigger than Deluxe today, and I am NOT paying $37 for a deluxe figure. Hopefully places like Kmart and Big W will have them for cheaper when they finally get stock.
