The new operator of the Darwin-Mandorah ferry service says it is possible a car ferry could be introduced on the route.

Sealink Travel Group will take over the service next month and says it plans to try and boost tourism to Mandorah.

Managing director Jeff Ellison says the company, which operates Captain Cook tours on Sydney Harbour as well as boat services in South Australia and Queensland, has plenty of experience running car ferries.

"We operate car ferries in South Australia and we have previously operated them in New Zealand," he said.

"It is part of our expertise and you never know what might happen down the track."

A new ferry will be used for the service from next month.

Mr Ellison says Sealink will maintain the current timetable.

"Initially, we will have one of our vessels from Townsville ... come up there and operate, and that's actually a larger ferry," he said.

"It will be replaced by a brand new one that will be there by the middle of September."

Mandorah and the Wagait Beach area are only a 15-minute ferry ride from Cullen Bay in Darwin, but travelling there by road involves a trip of about 130 kilometres.

Development of the area has long been a dream in the Top End capital.

Earlier this year, the operator of the popular Mandorah hotel announced that the pub would cease operating at the end of this dry season.

Publican Nick De Cantalo said the costs of repairs and maintenance at the old building had grown to be too daunting.
