The tower is expected to enhance 4G mobile coverage for those travelling along Hassell Road and the New England Highway between Muswellbrook and Singleton.

"It's fantastic that we have been able to bring improved coverage to the Upper Hunter, reducing call drop-outs along the New England Highway and enabling residents to stay connected with their friends and family through reliable voice and data access," Optus' territory general manager for North West New South Wales Chris Simon said.

"With a significant number of people travelling between Muswellbrook and Singleton along the New England Highway each day, we understand the importance of having reliable mobile reception in these areas and have taken action n to ensure this is the case with the build of this new tower.

"It's great to know our customers are benefitting from our continued network investment in the region and this latest site reinforces Optus' commitment to providing fast and reliable mobile and internet coverage across Muswellbrook."

Hunter MP Joel Fitzgibbon also welcomed the news.

"Reliable telecommunication services are so important to rural and regional Australia and largely relies on the investment of commercial providers and their commitment to delivering service to customers all over Australia," he said.

"The new infrastructure will boost coverage and rectify call drop-outs along the busy New England Highway.

"I'm pleased Hunter locals, those travelling to work and through the region, will now benefit from better mobile coverage."
