Cyber Shockwave and voy. Shockwave are at k-Mart Mandurah, as well as Cyber Huffer.

Also, I've managed to find only 1 Year of the Snake Omega Supreme (which I promptly bought at Big W Man.) but I haven't seen him ... anywhere else. I grabbed the last one, K-Mart still has the YotS Fatimus but I have the orig Energon one so I've given it a miss.
