Australia post refusing to deliver package

This is the age old story. I was home all day. There was no attempt to deliver - I didn’t even pop out for 5 min and no one buzzed.

They are now refusing to “re-“deliver (in brackets because based on evidence they never tried). I understand they’re busy but you simply can’t charge someone for a service you don’t even attempt to deliver - pun intended.

What are my options? 😤
