I was under the impression that it wasn't illegal in QLD, but I guess I should have read the QLD page when I was looking over Tiby's site...
When I called the QLD police a couple years back about owning toy/replica guns, I was told I didn't need a permit, and there wasn't a problem. I guess they were wrong, and just guessed.
If it really is currently illegal to own Megatron in QLD, I'll have to keep an eye on any QLDers who talk about Megatron now as well.
