Not sure about the Blu Ray mate, depends on where you order it from and what version. I'd have a look at what different aussie stores such as the aus JB Hifi will have to sell on thier websites.
As for Jetfire, I wouldn't hold your breath. The last lot of generations toys to reach our shore were the AoE and the Fall of Cybertron toys. It seems unless it's related to a big release in another entertainment genre that most Generations toys don't reach here
