The sight of a deadly brown snake eating a carpet python would be enough to give most people the creeps, but for Brisbane snake catchers Sally and Norman Hill, it was a rare and fascinating display.

The pair were called to a home in the Ipswich suburb of Goodna, west of Brisbane, on Monday afternoon where the chilling scene unfolded.

"We've never seen something like this before, it's very rare any snake catcher gets an opportunity to witness something like this," Ms Hill said.

"We always heard the old saying 'if you've got a carpet python you won't have a brown' so obviously that's a myth."

Ms Hill said they stayed at the property for a few hours to allow the snake to finish its meal.

"We just put him into the bag, if you disturb them too much they'll regurgitate their meal and it's just a waste."

Brown snakes usually eat mice, frogs and lizards, but have been known to eat other snakes, even other brown snakes.

Ms Hill said the incident could have been caused by population pressure leading to competition for food, with the number of sightings of browns increasing in recent years.

"We started in 2015, so we have pretty much doubled what we were doing when we started, " she said.

The incident follows pictures being widely shared online of a large python eating a fully grown wallaby near Cairns on Sunday afternoon.

A woman was also bitten by a wild green tree snake at Australia Zoo north of Brisbane on Monday and was taken to hospital as a precaution.
