The work will take place from Wednesday, January 17, to Wednesday, January 31.
These works will require some temporary service disruptions or reduction in mobile coverage.
The network will be fully offline between Monday, January 22, and Friday, January 26.
The works are intended to improve mobile connectivity in the existing coverage footprint.
The rollout of improved connectivity in Kialla means customers with Telstra mobile services and devices will be able to enjoy a better mobile experience.
Telstra regional general manager Jenny Gray apologised for the disruption and said the work would be finished as quickly as possible.
“We have to turn the site off for a few days to perform the significant work needed to improve our mobile network in the Kialla area,” she said.
“While coverage and capacity will be impacted during this time, we want to keep the amount of time the site is off air to an absolute minimum, and give the community as much time as possible to plan for the disruption.
“Once it is all done, residents should notice an improvement in their service.”
Landline services, NBN internet services and mobile coverage from other providers will not be impacted during this time.
Telstra mobile customers will be receiving text messages advising them of the upcoming works.
