Authorities searching for a missing Western Australian farmer who disappeared on a solo fishing trip have delivered a tragic update in their search efforts.

Mark Adams, a 62-year-old Woogenellup farmer from the Great Southern region of WA, went missing on December 3 while on a fishing trip off the Albany coast.

WA Police on Friday announced a body had been located, following recovery efforts on Thursday night.

Authorities have announced formal identification “is yet to be completed” but believe the body is to be Mr Adams’.

“We sincerely thank everyone involved in the search for their tireless efforts, care and compassion.”

A ‘privilege’ to work with

The grain grower had farmed in Woogenellup, east of Mount Barker, for decades and held positions with various agricultural groups including membership of the Grain Section Council with the WA Farmers Federation for over 15 years.

He was an outspoken advocate for farmers on several issues, including the state’s gun laws.

WA Farmers president Steve McGuire said Mr Adams was a highly respected and innovative farmer and would be sorely missed by the state’s farming community.

“His leadership, integrity and commitment to the grains industry earned him the respect of growers across the state,” he said.
