The company's plans were to make cuts in its marketing, networks, IT, human resources, wholesale, satellite, corporate and small-to-medium size business divisions, a report in The Australian Financial Review says, quoting sources in the know.

The telco confirmed the cuts, with a spokesperson telling the AFR: "Since launching a new strategic direction just over two years ago, Optus has made a number of operational changes to reposition its business as a highly integrated, innovative, and content-driven multi-media brand."

"Today employees across the organisation were updated on the strategy. A number of employees were informed of changes to their individual reporting lines, and around 320 employees were advised that their roles have been made redundant.

And the spokesperson added: "Optus will continue to review its cost base and evolve the way we work.

"As a result, we anticipate that we will make a number of further structural changes to our business this financial year, which will result in further redundancies over the next 12 months."
