A South Australian town is in shock after a father drove off a wharf killing himself and his two young children.

Police divers recovered the bodies of Damien Little and his children, Hunter, aged about 1, and Koda, 4, from inside the submerged vehicle at Brennan's Wharf, Port Lincoln, on Monday.

According to the Daily Mail the car was driven off the wharf at high speed into 30-metre deep water.

Detectives said they were not treating it as an accident.


A rifle with a telescopic sight was also recovered from the water.

Witnesses described seeing the car nose-dive into the water after driving off the wharf at up to 80km/h.

Little, aged in his 30s, had reportedly posted a suicide note on social media at 5.45am on Monday. However, the note was removed by his wife, Melissa, who shared the Facebook page with him.

A neighbour told The Advertiser Melissa and Damien were "doting parents".

A friend said Little had seemed "absolutely fine" only days prior.

"He is a normal guy, he is not a big drinker or anything like that, with a family, and I could not sense anything was wrong when I spoke to him. I have never seen a bad side."

Port Lincoln mayor Bruce Green told the Daily Mail the town was "shocked and very sad".
