Bayer Big Fish Challenge final hosted in Tasmania

Little did he know that he would end up in the finals of the challenge, held in Tasmania for the past two years.

Despite not fly fishing before, Mr Tier, of NSW, and an agronomist with Nutrien Ag Solutions, said he still managed to land just one fish over the weekend.

"I have never fly fished before, but with the support of all the guys here I did manage to land one fish," he said.

The Bayer Big Fish Challenge is hosted throughout Australia during the year, but the finals were held at Currawong Lakes in Northern Tasmania for the second year running.

The top two teams from each state were invited to participate in the event, which raises funds for mental health programs such as the Ag Spirit Retreat, run by The Fly Program.

Founder Matt Tripet said the program's focus was on mental health and preventative health through "adventure therapy" retreats.

"We use things like fly fishing and mountain-bike riding to connect with men who are having problems with anxiety and mental health and use it to give them tools to support and cope," he said.

Bayer national account manager Ben Thompson said the Bayer Big Fish Challenge had been held for three years.

About 500 competitors in state teams were competing throughout the year, and it all culminated in Tasmania.

He said the challenge also helped to promote self-care and mental health tips and tricks, with guest speakers and other sessions held throughout the event, when the teams weren't fishing.

The Big Fish Challenge was held on February 27 and 28.
