Overseas caller with English accent. Hard sell for investing in the commodity market. Clearly a scam as this type of trading is illegal. They start by saying that "I understand you spoke with one of my colleagues last year" to try to suck you in. I haven't had this call for a while, but I used to get them every few weeks a few years back. Just hang up on them.

Every six month these drop-kicks ring to get me into investing in stocks and shares.
Tell I'm not interest now or ever and stop calling 0 but they keep calling.

They are unable to provide an AFSL.
I believe it is illegal for them to make unsolicited calls re: investments.
Scammers

This number at first looked like a NSW number. But it is an overseas group using heavy handed tactics to sell investments. Suggest you block them or just hang up.
