Doctors overseeing the transfer of asylum-seekers to Australia have complained treatments are being delayed because their advice is not being given to Minister for Home Affairs Peter Dutton quickly enough.

The Independent Health Advice Panel — which assesses applications for people in offshore immigration detention to be brought to Australia for treatment — reported it had assessed 57 transfer requests between July and September.

The panel, established in March under the so-called Medevac laws, sided with the Minister for Home Affairs in most cases, rejecting 45 requests from doctors for people to be transferred.

But it overturned the minister’s decision in 12 cases, where it deemed transfer to Australia for medical or psychiatric treatment was necessary.
