Operating revenue was up 11 per cent to $2.29 billion, while annual net profit grew one per cent to $841 million.

In mass market fixed, operating revenues were up three per cent, driven by an increase in Optus’ broadband customer base and a range of compelling home broadband and entertainment offers.
Quarterly EBITDA grew 10 per cent to $723 million driven by strong mobile service revenue growth and lower selling costs from higher take-up of Device Repayment Plans.
