The second wave of Construct-Bots are now at Amazon.
Elite (US$17 - currently on sale for US$16)
Hound
Optimus
Megatron (Galvatron)

Scout (US$11)
Thundercracker
Bumblebee

Also new is Wave 5 Beast Hunter Deluxes, but looks like the Scalpers already got to Prowl, as it is currently not in stock at Amazon. (it could return though if they restock).
Night Shadow Bumblebee US$17

They also have in the third wave of Legions (Blight, Windrazor, Rippersnapper), but are about $8 each though, so only consider it if you can't find them at Woolies here.
A third party has Hun-Grrr for $9, but the weighting looks too high, so even if you could buy it, the postage would be pretty expensive.

Plus, for the Rescue Bots fans, the new game console thingy (similar concept to Skylanders, and the hoards of imitations) for US$60, but is currently on sale for $44.
Not sure if it will work on Australian TVs, as it might require NTSC compatibility... or something else technical that is different between our two standards. I bought one anyway, so if if it works, I'll make a note of it here. If not, I have an expensive display figurine.
