Church sanctuary - does it exist under Australian law?

We've seen it in movies- a man pursued by soldiers or police runs to the church's heavy wooden doors, flings them open and dives inside the church claiming sanctuary. The brave priest bars the entrance and the pursuers stop at the doors, fearing what might happen if they cross the threshold and break the protection of church sanctuary. So long as the fugitive remains inside the church, the powers outside church walls cannot touch him.

Several Australian church leaders recently invoked the ancient rite of sanctuary offering protection of the church to asylum seekers, including babies born in Australia, who are due to be deported to the Nauru after a High Court decision ruling the government policy of offshore detention was legal.
