A MAN has recorded a "strange sound" over the Easter weekend while staying in Bonnie Doon, which has managed to garner some national attention.

The sound, which echoed across Lake Eildon, lasted for approximately two minutes according to Jai Brooks, who posted the video to social media.

Mr Brooks told the Daily Mail he had finished clearing out an old cabin at the caravan park and went down to the lake to have a look at the water with his siblings.

"We had only been there a few minutes when one of my brothers said, 'Can you hear that?'" he said.

The source of the noise was not clear and many who have seen the video made guesses as to its origin.

Among the theories, people thought it could be the sound from a jet engine bouncing off the water or an echo of something from somewhere else on the lake.

Mr Brooks said he and his family weren't afraid, but admitted they have no idea what it was.

"We were more in disbelief and confused," he said.
