There's been seals, even whales, but have you ever seen a dolphin in the Tamar River?
The unusual visitor was spotted right in the heart of Launceston about 10am on Wednesday, first behind the QVMAG Tramsheds Function Centre and later down towards Seaport.
Aran Price, of Launceston Kayak Tours, said he couldn't believe his eyes when someone in his group made the sighting.
"We had only just gotten in the water. Someone yelled out 'look over there'. I thought oh it will just be a seal, let's get a bit closer. Then we realised it was a dolphin," he said.
"It was just disbelief. But I think it's absolutely amazing and hopefully a sign that the river is getting back to a better quality."
The dolphin reportedly spent a bit over an hour taking in the sights of the North Esk River.
Mr Price said they watched it for some time from the front of Customs House, near Boags Brewery.
"I have been doing these tours since 2016 and it's the first time I have seen a dolphin this close," he said.
Institute for Marine and Antarctic Studies Associate Professor Mary-Anne Lea said a variety of marine mammals had been sighted in the Tamar over the years.
However, she said it was important that any sightings were reported to help scientists learn more about animal movements.
"When we consider the movements of dolphins, whales and seals, it is often seasonal," she said.
"So there could be prey items in the river.
"It's important when these types of things happen that people report their observations to DPIPWE, and to just observe, not harass these animals."
Associate Professor Lea said seeing a dolphin in the river, so close to town, was relatively rare given the greater concentration of people in the area.
A DPIPWE spokesperson said coastal marine mammals such as dolphins were known to visit Tasmania's large estuaries and river systems, often coinciding with seasonal movements or changes in the abundance of food sources within estuaries such as the Tamar.
"Marine mammals that visit the upper reaches of Tasmanian estuaries generally remain for periods less than a week," they said.
"Estuarine waters do not pose a risk to marine mammals such as seals and dolphins, however they may suffer skin and eye irritations if they remain for more than two weeks.
"Limited visibility and the confined nature of some river systems may affect a dolphin's ability to avoid vessel interactions so people who use the river are asked to be vigilant and keep their distance."
