The woman, known as Cheryl, made the shocking discovery yesterday when she spotted the deadly snake on her Christmas tree.
Cheryl, immediately called professional snake catcher Barry Goldsmith to her home in Frankston, a Melbourne suburb.
It turned out she'd had a lucky escape.
"The snake is among the most dangerous of Australia," Goldsmith told CNN.
Tiger snakes, very common in Southern Australia during summer, are protected in many states and usually released back into the wild when found inside houses.
"Cheryl did exactly what she was supposed to do," he said. "She closed the door, put a towel underneath and called me."
The snake catcher added that if people don't touch the snakes and stay calm, they don't usually get bitten. Trying to move or kill the reptiles, on the contrary, can be fatal.
