Ok guys, thanks for all the info.
I contacted Graf & Sons regarding importing procedure and am now shocked to discover new information.
This was their reply.
If it is for controlled commodities an export license will be required as well. We can apply for a license on your behalf for USD $50.00. I will need a signed purchase order, BIS-711 and your Australian International Import Certificate.

There is also a USD $50.00 AES filing fee on any licensed shipment under USD $1,000.00. The license must be in place before I can accept an order from you.
It is now totally prohibitive for me to bring in brass, bullets or ANY other firearm parts/reloading goods if they come under the first sentence above. I contacted customs here, they will destroy any brass or bullets that do not have the above permits.
I now see this is another way they are trying to remove access to firearms, it will be impossible to reload soon, as no primers are available here…
Cheers.
