Bianca, 13, was moving a portable swimming pool at her Naringal East home when the venomous snake attacked on Saturday afternoon.

Fortunately her younger siblings Chelsea, 7, and Benjamin, 5, wasted no time getting her help.

"I was shifting the pool, which was all crumpled and the snake jumped out and latched on to my arm," the teenager said.

"I screamed and fell back onto my dad's car.

"Chelsea and Benjamin were there and I just told them to go inside and get help, which they did."

Bianca was one of three tiger snake victims hospitalised over the weekend.

An Allansford man was bitten while working in a garden and Portland's Gavin Carr is still recovering in South West Healthcare Warrnambool's intensive care unit after being bitten in his backyard on Thursday.

"They're about," he said from his bedside yesterday.

"Act fast if you are bitten."

Bianca's siblings raised the alarm with their mother Rosie Wilson, who hastily bandaged her daughter's arm with a bandanna.

"It was the only thing I had. Bianca had only bought it the day before," Ms Wilson said.

The young family did not wait for an ambulance, instead rushing to the Warrnambool hospital where she was cleared of injury and later discharged.

"Luckily the snake did not inject any venom, it only latched on," Bianca said.

"But it was a terrifying experience.

"You aren't lucky with snake bites twice. I can't thank my brother and sister enough."

Tiger snake bites can be fatal.

Ms Wilson urged all parents to be alert for the aggressive reptiles over summer.

"You have just got to be so vigilant," she said.

"They can be anywhere."
