A number of major retailers here in Australia have recently been stocking some of the licensed Jada diecast Transformers vehicles. Not all of them, but several different ones across multiple sizes, to give us a taste of what they have been producing in the last couple of years.
Currently they are hitting Target, Kmart, BigW and Toyworld, but not all of them in all stores.

Large sized - Gen1 Optimus & 70s Camaro Bumblebee with coin ($49 at Target) & 70s Camaro Bumblebee without coin ($39 at BigW).
Mid sized - Gen1 Optimus, 2007 Movie Optimus, 2016 Camaro Bumblebee ($15 in Target and $18-20 at Toyworld - only Gen1 Optimus at Kmart for $15 - also was at BigW a year ago so might return there)
"Nano" sized 3-pack of 2007 Movie Optimus & Bumblebee ($15 at Target - might also be at BigW)
Remote Control - 2016 Camaro Bumblebee ($39 at Kmart).

And spotted by someone on facebook is a Bumblebee Movie VW Bumblebee at a Mr Toys in Brisbane (photo posted to our facebook page by Tyson Richards).

If you see any others, or at other retailers, let us know.
