A morning of laundry duties turned into a fascinating home version of the Discovery Channel for a Sunrise Beach woman when she walked outside to discover a huge snake ingesting a bat.

Mille Stoevring and her partner Shane Tuer were shocked to find the massive carpet python, which was at least three metres long, halfway through its meal.

The couple watched with fascination more than fear, as the snake arched its mouth and twisted its slippery body to manage the winged-feast.

"We were there filming about 20 centimetres away, the snake wasn't fazed at all," Miss Stoevring said.
