Can I use the 72-hour transit visa?

I currently hold a work Z type for living and working in Beijing, but it expires on the 10th July. I will be in Australia or Indonesia travelling then, but want to travel via Beijing on the way home on 17th. Can I have a 72 hour free transit at this point? I have a booked flight home to UK for 19th- so would only be there 2 days.
