Yep I have mate and I found out some pretty interesting news from them ,That is they have bought a foundry down the road because they werent getting the quality they needed from them and could do it better themselves.
Anything that was produced in Australia they make new ,Anything produced outside the country can be ordered in but not as a blank disk.
So yes they do make them in a blank but the price is near ridiculous.
Just hoping someone out there may have some with no use for them
,Thanks again smithy
