It's definitely from Australia Post. The details and the number is listed on their website here. https://auspost.com.au/text-your-choice

Expand the question 'Why is this a different number to what I usually get Australia Post text messages from?'
And the answer from Auspost is 'All text messages for the Text Your Choice service will come from the number 0448 008 003. You may receive delivery status updates from a different number prefaced AUSPOST, which is a non-reply message.'

Scam. Especially if it has a URL with the domain .st
Usually has a legitimate URL to Aus Post help site on the bottom.
Somehow they've also figured out how to spoof the real AusPost number as originator, but still have the .st domain.
