Tessa O'Halloran is a contestant from Australian Survivor (2017).

A die-hard fan of the game, Tessa was relegated to the minority after her allies were blindsided early on in the game. However, thanks to Mark Herlaar and the power struggle that arose after his elimination, she was able to find her place on top of the tribe, allowing her to travel deep into the game before being relegated to the minority shortly before merge. However, after an Immunity Challenge win, Tessa was able to deflect the targets of her alliance, leading the blindisde of threat Henry Nicholson. Unfortunately, this in turn resulted in her downfall, as she was blindsided by her allies the very next Tribal Council due to the threat she posed to the other players. Post-elimination, she was deemed to dangerous to be on the jury by eventual winner Jericho Malabonga, who used the Juror Removal twist on her.

Age: 29
Occupation: Doctor
State: Victoria
Tribe: Samatau

Always underestimated by her work colleagues and patients because of her age and gender, Tessa is highly intelligent and ready to compete.

Studying to become a doctor, Tessa worked under high-pressure conditions while attending lectures and studying to pass her physician's exam. She is now one of the youngest doctors at her work.

Tessa's youthful looks have meant patients and colleagues do not always think she knows what she is doing – but do not be fooled.

"I am quite used to people looking at me and thinking I am too young to be doing the job that I am doing, but I do it well. I do not make many mistakes. I know what I am doing," she said.

Tessa's strategy is to form an all-girls alliance and to work her magic when their backs are turned.

"Hopefully I am too small and blonde for the other survivors on the island to realise it, but I will work behind-the-scenes to play them against each other.

"They will not want to mess with me. When I am annoyed, I tend to have a quiet simmer. I then go out to get revenge and they will not see me coming."

Tessa wants to win Australian Survivor for her family, especially her mum, and she does not feel any guilt about her strategy.

"I do not think that heroes go far in this game. People who say they are playing with honesty and integrity are infuriating. It is a game, it is not real life."[1]
