Optus-Singtel has confirmed it will slash 157 jobs following a strategic review of its operations announced in February.
The move will see 130 IT roles sent offshore and a further 27 roles affected as a result of plans to close its Silverwater-based after sales Service Centre in late September.
Led by chief executive Kevin Russell, they are the latest in a series of cuts which has resulted in the loss of more than 1300 jobs since his arrival at the company.
A spokesperson for Optus said staff in IT division were advised in February of plans to outsource some local IT functions to third party vendors.
"Following a review of our IT division, we have identified around 130 roles that are affected," she said. "We are working with employees who are affected by these changes, and where possible, we are exploring redeployment opportunities for our people."
She said the closure of the Silverwater after sales service centre was the result of Optus bringing its handset repair service in-store.
"We are expanding our handset repair program so that more customers will be able to replace their broken phones immediately while they are in-store," she said. "Around 27 roles will be affected as part of the closure of our Silverwater facilities.
