When you do a little research I have found Three states have alerts out and from a conversation I saw on Yamma there seems to be nothing in NSW.
I have copied Vatche"s reply to this question. The Tasmanian alert from Catholic Schools includes Talc However S.A and Qld don't include talc.
In our area we also had serpentine rock samples and Talc rock samples so they are all double bagged or gone now rather than wait to see.Below is a pdf link you will have to copy and paste it in as it hasn't copied as blue link

I'm aware qld has sent a directive regarding talc, suppliers are aware of the situation. Will be inquiring and finding out what the NSW stance is.
