Bumblebee is in wave 2. Picked up the G1 Optimus and Ratchet from Big W Mt Ommaney yesterday, they still had the rest of series 1, from what I could see. $4

Target had heaps of deluxe Strafe, Slash and Drift in an AOE pallet.

Also, Coles had the G1 custom Kreons Optimus, Soundwave and Starscream.
