The spotted python left the man with a small nip on the finger before quickly retreating to a bedside table.
Mr Hagan said it was one of the fattest snakes he'd had to relocate.
A warm bed would seemingly be the ideal spot to curl up for a winter hibernation, but Mr Hagan said snakes are still active because of unseasonably warm weather.
"We're still getting calls that pets are being eaten, which we usually see die off around this time," he said.
Mr Hagan also relocated a coastal carpet python from a boat at Kuranda over the weekend.
