OPTUS will cut close to 500 jobs across its network as part of a major restructure for the national telco.
In a statement the company admits it is "proposing to make a number of roles redundant", although media reports suggest this would affect up to 480 roles.
It is understood the staff changes would be rolled out over the next four weeks.
The staff cuts will help drive the company's "transformation strategy", which would include "multi-skilling front line staff" and allow the company to "reshape its workforce with the skills required in an increasingly digital world".
In its statement, the telco does not explain what those skills are, or why they are not being applied to those already working for the company.
Optus announced the cuts on Monday and vowed to consult with workers and redeploy roles where possible.
Last month, confidential documents leaked from Optus to national media suggested the company planned to cull 1011 staff between April 1 2016 and March 31 next year.
At the time, an Optus spokesperson denied the figures but said Optus "will need to make future changes to the way we organise ourselves to help support our business goals".
