The bus service from Walcha to Port Macquarie is set to become timetabled from September 16.
Member for Tamworth Kevin Anderson said locals had embraced the trial service between Tamworth and Port Macquarie since its introduction in Mach 2018.
"Residents in regional communities often rely on coach services to remain connected to their friends, families and essential services - and this new service has really hit the mark," he said.
"Locals say the connection has made a great difference in helping them visit loved ones in Port Macquarie, Tamworth and in between. It is exciting to see this successful trial transition to a timetabled service."
Mr Anderson said the coach service provided an easy and regular connection for Walcha locals to get away for a weekend break.
The service will continue to operate as a day return between Tamworth and Port Macquarie via Walcha on Monday, with an afternoon departure on Friday and a return service on Sunday afternoon.
The service connects towns such as Kootingal, Moonbi, Bendemeer, Walcha, Long Flat, to Port Macquarie and Tamworth. It also connects to XPT services at Wauchope so customers can travel to North Coast communities.
"It's great to experience a bit of sea change, and that's what has driven locals to get on board with this trial," Mr Anderson said.
"We know connecting regional towns provides a tourism boost, but it also provides new shopping and dining opportunities for visitors, which supports small businesses."
