This two-metre-long red belly black had snake catcher Geoff Delooze rethinking his life decisions.

The "abnormally large" and "heavy as" snake, which according to Mr Delooze weighed about 10 kilograms, was found hiding under an airconditioning unit at an engineering firm in Cameron Park, Newcastle, on Wednesday.

Mr Delooze got the call to pick the snake up, and couldn't believe his eyes when he caught sight of the "ferocious eater", The Newcastle Herald reports.

"I have to admit, it had me looking back at these people thinking, 'What the hell is this? My call-out fee isn't big enough for this,' " he said.
