The company also said it would spend $3 million to improve the 4G and 3G mobile network in Albany and along Albany Highway.
Optus’ state manager for Western Australia, Jonathan Conway, said, “Optus will build a number of new sites to improve network coverage and customer experience for residents, businesses and the two million plus yearly visitors to the region.”
Four new sites will be built at Davenport, Preston Beach, Gelorup and Dardanup in the next two years.
“Optus is committed to improving mobile coverage and providing faster internet download speeds for people living, working, and visiting the South West region including Bunbury, Margaret River and Busselton," said Conway.
“We’ve listened to feedback from our customers and businesses who all echo the same message that they want better coverage and faster download speeds especially along the Bussell Highway.
“Once work is completed, customers will benefit from fewer call drop outs, better indoor and outdoor coverage and smoother steaming to mobile devices.”
As far as the Albany and Albany Highway were concerned, Conway said: “In the next two years we will build five new sites in Albany CBD, Albany North East, Gledhow, Beaufort River and Kendenup.
“We have recently built and activated two new sites at Orana and Spencer Park which are already providing improved 4G and 3G coverage for residents, businesses and visitors.
“Coverage has also improved at the Albany Hospital and the surrounding area.”
The announcements are part of the company's $1.5 billion commitment to improve its network this year.
