I'm currently in the UK, where Transformers are also imported. I checked out some prices of what I could buy today. None of these are 'sale' prices:

Prime Powerizers (Voyager Prime and Megatron) are £22.99 - about $34.50AU.

Prime Deluxes are £12.99 - about $19.50AU.

Prime Cyberverse Commanders are £8.99 - about $13.50AU.

Prime Cyberverse Legions are £4.99 - about $7.50AU.

So if UK retailers can import these toys and sell them at a profit at the above prices, Aussies are being rorted. As we have known for many years.
