Two backpackers have revealed how they thought they were going to die at the hands of Salt Creek attacker Roman Heinze.
German backpacker Lena Rabente and her Brazilian friend Beatriz have told 60 Minutes how they tried to outsmart and outrun their attacker at a remote beach in South Australia's Coorong National Park.
"I thought, I'm going to die. I was really sure about it. Like, I already imagined myself dying here and that's why I didn't want to give up in the end," Ms Rabente told the program on Sunday night.
The backpackers met Heinze while in Adelaide. He agreed to give the duo a ride to Melbourne but instead drove them to isolated sand dunes at the Coorong's Salt Creek.
After tricking Beatriz into going to look at kangaroos, Heinze tied her up and sexually assaulted her.
"I felt like I was in a horror movie," she said.
"I had to convinced him that I was on his side."
Instead of fighting Heinze, she tricked him into returning to their camp, where Beatriz screamed for her friend.
"He (Heinze) said something like 'I just wanted to try her'," Ms Rabente said.
Heinze then used a hammer to hit Ms Rabente several times before trying to run her over with his 4WD.
"I didn't know what he had hit me with because I couldn't see, immediately, but I thought 'that's the end' because the smash was so hard," she said
The women ran for their lives in different directions, with Beatriz eventually flagging down a group of fisherman driving past.
"(They saw) a girl, naked running waving for them ... Once I got in the car and I started screaming, they saw that it was serious," Beatriz said.
Meanwhile Lena had run at Heinze's car and crawled onto his roof so he couldn't run her over.
She eventually bargained with him to drop his weapons, and ran for it, also taking sanctuary with the fishermen.
Since the February 2016 attack, Beatriz struggles with everyday things.
"I prefer not to be outside after sunset because I just don't feel comfortable, I don't feel safe anymore if I see someone on the street, I start thinking that they might be following me," she said.
Roman Heinze was jailed for 22 years in May after being found guilty of six charges including indecent assault, aggravated kidnapping and endangering life.
He is appealing his sentence.
