Authorities were called to a rural residence at Lottah, near St Helens, at 7:00pm on Saturday night.

When police arrived they found a 47-year-old man dead from what police said was a single gunshot wound.

The 65-year-old man, who was also at the scene, was taken into custody.

Tasmania Police Acting Inspector Bob Baker said he believed the men were neighbours and it was alleged there had been "some sort of incident" between them which had escalated.

"My understanding is we received the call at 7:00pm and the incident's occurred shortly before that," he said.

Acting Inspector Baker said he was unable to elaborate on the nature of the alleged disagreement.

He said the alleged offender was the victim's neighbour and he was the one who alerted authorities.

"I understand both parties are known to each other," he said.

"As I say, we're still investigating."

Acting Inspector Baker said it was also not certain whether the shooting happened on private property or adjoining public land and police believed there were no other witnesses.

"We'll continue investigations to piece the whole thing together," he said.

The accused man appeared in an out-of-sessions court hearing on Sunday morning and was remanded to re-appear in court on Monday afternoon.

Acting Inspector Baker said he was "unable to comment on [the accused man's] state of mind".

It is understood the victim lived alone.

Police are yet to release the names of either of the men.

Lottah is situated between St Helens and Scottsdale on Tasmania's east coast, accessible only by a gravel road.
