With the permission of their family, Tasmania Police has released the names of the two Tasmanians on board a light plane that has been missing since Saturday.
Gregory Vaughan, 72, and his partner Kim Worner, 66, of Deloraine, plus their dog Molly, were in a light sport aircraft that took off from George Town airport about 12.45pm on Saturday.
The plane is a two-seater Bristell S-LSA in distinctive green colour.
Tasmania Police Inspector Nick Clark said the plane did not arrive at its destination in central NSW as scheduled and family members raised the alarm on Saturday evening.
"The two people on the plane have not been in contact with anyone, or aviation authorities, since they left George Town," Inspector Clark said.
"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."
A Tasmania Police helicopter crew conducted sweeps of the state's northern coastline between George Town and Turners Beach today however, there has been no sighting of the plane.
Inclement weather and low cloud complicated search conditions, while boats did not go out on the water due to the rough conditions.
Inspector Clark said Tasmania Police would continue searching on Wednesday.
"Significant resources have been utilised in the search and Pol Air will continue to be used over the next two days, at which time the search efforts will be re-assessed based on any possible new information that becomes available," he said.
"The longer Gregory and Kim are missing the greater the concerns are for their welfare."
