Well I have not imported brass so no idea if a B709A is needed.

Came in once from Africa via Perth without the ammo on the B709A and had them confiscate all the loaded ammo, but they let me keep the used brass. The loaded ammo was sent to Adelaide and I got it back once I applied for a permit for it.

In SA a licence is required to buy across the counter loaded ammo, primers and powder I believe.

Brass and bullets, nothing is required.
