you talking about UPS or USPS (united states postal service).
If it's USPS, it has taken me 7 - 10 working days in the past. That's because when it arrives in Australia, it's then handled by Australia Post. As far as tracking, USPS from my experience takes forever to update their status. Not to mention, once the parcel was in Australia, their tracking system no longer gave updates.
If you have a tracking no, best to call Australia Post and mention it to them.
