[PC, Steam] The Quarry US$21.40 (Approx A$31.65), The Great Ace Attorney Chronicles US$14.92 (A$22.07) @ GameBillet

So I'll combine these two GameBillet deals considerately into one post, they're both almost 66% off their steam/RRP price.
Note that The Great Ace Attorney Chronicles is 50% off on Steam's Capcom sale, but you'll still save about $5-6 at GameBillet.
Try code 2023GB5 for another 5% off, I found it on the internet.

The Quarry:

A well rated game as per its steam page: https://store.steampowered.com/app/1577120/The_Quarry/.

Great Ace Attorney Chronicles: Expired

If you've played the previous Ace Attorney Chronicles you'll know how fun they are.

GameBillet is generally a reliable source and I've never had an issue before.
