The reward for finding bushwalker Prabh Srawn has been doubled, almost one month after the Canadian man went missing in the Kosciuszko National Park.
The 25-year-old's family is now offering $100,000 to any searcher who can rescue or recover Mr Srawn, who was last seen when he parked his car at Charlotte Pass Village on May 13.
The increase, posted on social media over the weekend, comes just days after they declared they will reward any searcher who finds the Canadian student, dead or alive.
Facilitators of the official Facebook page, titled "Help Find Prabh Srawn - Missing Bushwalker", posted the notice.
It also emphasised the need for searchers to be well-experienced hikers, who register with the police and carry GPS equipment.
"We want everyone to be safe, all lives are valuable," it read. "Please only hike if you feel you are well prepared to do so."
NSW Police have scaled back the search efforts and the Westpac Life Saver Rescue Helicopter officially withdrew from the search last week.
The family of the Bond University student plan to stay in Jindabyne until searchers found Mr Srawn, who was last seen wearing a white t-shirt and blue jeans nearly a month ago.
NSW police believe he may be wearing a red and black ski jacket including the words "Frogg Toggs".
