The works are expected to take seven days, during which the site will be switched off for periods of up to 10 hours to allow works to be completed safety.
Telstra said the upgrades were designed to deliver faster downloads, smoother streaming and reduced network congestion.
A Telstra spokesperson said the upgrade reflected the growing demand on its network.
“As data use over our mobile network continues to grow, adding extra 4G/5G capacity to our mobile site in the area will help deliver faster downloads, smoother streaming and less congestion for customers,” the spokesperson said.
“While disruption is required while the upgrade is under way, we’ll only be switching off the site when we need to and will have it back online and working better than ever as quickly as possible.”
Telstra advised that timings or impacts may change due to factors outside its control.
