The new tower is near Caves Road and improves the coverage in tourist routes through the Margaret River winery district, including the Leeuwin Estate Winery, Optus said in a statement.
Cameron Edwards, Optus Territory general manager Regional Western Australia, said: “We have been working hard over the last 12 months to improve mobile and data coverage in South West WA and this new site in Redgate is central to that commitment.
“Along with the amazing wineries, the Margaret River region hosts a number of world class events and concerts and this new tower will provide much needed coverage and ease the load on other sites in the area, particularly during the peak tourism season.
"These new sites continue to provide improved connectivity for our customers as well as offering real choice and competition for residents in the region."
This brings to 10, the number of mobile towers switched on in the last 12 months, the others being: Lakes Road, Beaufort River, Greenfields Peel Health, Boyup Brook, Molloy Island, Dardanup, Gracetown, Kendenup and Albany North East.
