Mark Herlaar (often referred to as Tarzan) is a contestant from Australian Survivor (2017) and Australian Survivor: All Stars.

During his time in 2017, Mark H. found himself outside of the seven person alliance, but found his niche on the tribe as Samatau's sustenance provider and fire master. Mark H. relegated himself in to the background of the tribe for the majority of the game, but made his first move on Day 11, after finding the Hidden Immunity Idol by a stroke of luck. He decided to give his idol to Tessa O'Halloran, knowing she was the seven person alliance's target and thinking he wouldn't be voted out for being the tribe's provider, thus potentially idoling Locky out in a 1-0 vote. However, Mark H.'s plan backfired, as Locky got suspicious of his behavior before tribal and was able to get enough votes to get him voted out in a 3-1-0 vote.

Age: 51
Occupation: Lime Farmer
State: Queensland
Tribe: Samatau

With his beloved wife, two children and six grandchildren at home cheering him on, lime farmer Mark is going to play hard and will not let his age stop him from giving the younger contestants a run for their money.

Mark owned and built a multimillion-dollar insulation business but lost it all when the Government introduced the rebate scheme, so he decided to rebuild his life as a regional lime farmer. The hardworking farmer has also sold firewood, worked in flea markets and invested in property and the stockmarket.

While he may have achieved a lot professionally, Mark's family means more to him.

"My kids and my wife are amazing people and so full of love for each other and that's pretty significant. For my grandkids to sit there and see Poppy on television and be like 'That's my Poppy', I want to win it for that."

Getting into the island vibe, Mark was recently in Vanuatu with his son where they built a grass hut and ate coconuts for two days. "We roughed it but I don't know how I'm going to do it for 55 days. I don't like sleeping on the ground," he said.

"I keep fit everyday by working and at least three times a week, I'll do a long walk. I'm pretty good for 51, I think. I should be ready to take on these kids."

Mark is a firm believer in doing the right thing but knows that when it comes to Australian Survivor, his moral compass may start to falter.

"My word is my bond and I teach my children and grandchildren that and we never break that. But this is a game. The door to the universe is wide open so I will jump in and see where I land. I have every faith in myself to do it. I don't know how but I will do it."[1]

Mark looked to be a provider for the Samatau tribe, and his outdoor and life experience made him an asset. However, Mark fell into the minority when ally Adam Parkin was blindsided at Samatau's first Tribal Council. That did not faze Mark, as he continued to be helpful at camp while trying to keep his main ally Tessa in the game. When the majority Samatau alliance split the vote against Kate Temby and Tessa O'Halloran, Mark ensured Tessa stayed by voting for Kate. That vote left Samatau with fewer members than Asaga, so Mark reminded Locky Gilbert that the tribe should consider voting out the weakest member Anneliese Wilson. However, Locky remained set on targeting Tessa first. Mark was faced with a moral dilemma: to hide cookies from his tribe and kept to himself, or to bring a big bundle of firewood to camp. Mark was torn because he was very hungry, but felt the right thing to do was to choose the firewood.

Samatau were thankful for his selflessness, although it did not change his position on the tribe. After Samatau lost yet another Immunity Challenge, Mark knew Tessa would go unless he found a Hidden Immunity Idol for her. They decided they wanted to use the idol to take out Locky, and tried to recruit AK Knight as well since it would improve his standing in the tribe as well. However, Locky became suspicious of Mark when he said he was willing to vote Tessa off. Tessa played the idol for herself, but Locky's alliance split the votes and Mark ended up falling on the sword for his ally.
