Hi I have been wanting to get my hands on a G1 Megatron robot that transformers in a sniper like gun to add to my collection

I want to know if this action figure is banned in Australia as this figure does not turn up that often

Am interested in this history of this action figure because I believe this is the fist action figure that transformers in a gun mode that looks realistic

I remember borrowing this somehow and it suddenly "vanished" under my mother disapproval of guns after a while. I think it has to be my favourite transformer toy ever

I also want to know if it is possible to buy this figure from overseas and bring it to Australia via post or is it too risky?

Any guidance or feedback would be great thanks
