Fairfax Media has received photos of the debris found near Augusta which investigators have since confirmed is not linked to the missing Malaysian Airlines flight MH370.

Mat Franklin and his son discovered the debris on Easter Monday four kilometres from Augusta.

Mr Franklin went to work on Tuesday before trying to report his findings.

"It looked pretty distinctly like a piece of aircraft. I didn't want to raise any alarms, I just wanted to get an opinion," he said.

Mr Franklin decided to get advice from the Busselton Aero Club on Wednesday who then passed it on the Busselton police.
