I called back number (08) 8448 0630 spoke to a guy who said I've reached a company in Brisbane but did not say the name.

Caller: Scammers

They are scammers and not to be communicated with.

Caller: Credit Corp

It took several attempts but they eventually spilled with the business name.

Caller: Unknown

Probably Credit Corp using yet another number-wish they’d update their lists as they’ve got the wrong details. No idea what they want but I’m not going to give my personal ID to a caller who won’t identify themselves and bombards me with calls.
Another number to block, getting sick of this after approx 50 calls!

Caller: Credit crop debit collection

Hang up block them

Called back and got robotic number resital
