A Tasmania Police helicopter crew will patrol the state's northern coastline between George Town and Turners Beach this morning as the search continues for a twin-seater light plane, reported missing late Saturday afternoon.
Tasmania Police Inspector Nick Clark said rough conditions on the water mean marine vessels will not be active in the search this morning.
"Inclement weather is limiting our search options, however we are continuing our efforts to locate the plane and its occupants and will be utilising the helicopter," he said.
"The plane in question is a two-seat, single engine aircraft, and a distinctive bright green in colour."
"If anyone has information that could assist the search, has seen a plane matching this description, or noticed anything such as unusual debris on land or in the water, they should contact Tasmania Police on 131 444."
The light plane took off from George Town airport on Saturday about 12.45pm. On board was a male pilot aged in his 70s, his female partner aged in her 60s, and their pet dog.
Inspector Clark said the plane did not arrive at its destination in central NSW and family members raised the alarm Saturday evening.
"The two people on the plane have not been in contact with anyone, or aviation authorities, since they left George Town," he said.
Extensive searching involving the Australian Maritime Safety Authority Challenger jet, Tasmania Police helicopter resources and marine vessels, has been undertaken along Tasmania's northern coastline, and into Bass Strait since Saturday night.
Tasmania Police Northern Commander Marco Ghedini has commended the search teams, which includes officers and volunteers, for their hard work and commitment during the operation.
"As we enter the fourth day of searching, police hold grave concerns for the missing couple, however we maintain hope as the operation continues," he said.
"Further assessment in relation to the ongoing search will be made in the coming days."
