Got a text with parcel number and link to what looked like a legit Aust Post website, but asked for money to complete. I ignored and blocked. Frustrating that I do happen to have Aust Post parcels I am waiting on. But I guess that's what the scammers rely on!

Same thing, received an SMS message quoting a 'parcel' number and that it was waiting 'at our distribution centre. Authorisaction w/out signature is required to complete delivery'. Then it has a link that they expect you to click on....
Out of interest I dialled this number and it actually rang then a recorded message saying 'this call cannot be completed at this time' in an Australian accent.
Avoid at all costs and block this number!

I received a notice saying the sticker had ripped on my parcel and to go to a link

received questionable SMS saying my parcel was being held 'at our shipping centre' and to click on a link.

Final warning

SCAM!!!
