St Helens Plains farmer Ben Brooksby started The Naked Farmer in 2016, which raises awareness of mental health issues in regional areas.

Mr Brooksby created a series of 2019 calendars, featuring naked farmers in the region and throughout Australia, as a fundraiser for mental health services. 

Through the sale of calendars, along with The Naked Farmer hats and underwear, he has raised $17,228.

 "I chose to donate the money to the Royal Flying Doctors Service because they do great work particularly around mental health," he said.

"They are a respected and well-known organisations that is doing great things in regional Australia.

"I am ecstatic at how well the calendars sold - I was hoping for more than $1000."

Mr Brooksby said the first batch of calendars sold out quickly, which was soon followed by a second batch.

He said altogether, about 1100 calendars were sold.

Mr Brooksby plans to tour Tasmania in June this year and create a 2020 calendar. 

Royal Flying Doctors Service Victoria chief executive Scott Chapman said there were many worthy causes to support and it took a unique approach such as The Naked Farmer to have an impact.

"We are grateful for Ben's efforts, as well as everyone who has bought a calendar or shared their story," he said.

"It's critical to raise awareness of mental health issues in rural and remote communities, both to increase the community's knowledge of mental health issues and increase their capacity to respond when people are in need, but also to overcome stigma and ensure people know how and where to access support when they need it. "

Mr Chapman said 100 per cent of the money raised would go to the service's mental health program.
