NBN Co says it is on track to reach its targets for this financial year after posting $3.5 billion of revenue in the nine months to the end of March – a surge of more than 20 per cent on the prior corresponding period.

It means the company – a state-owned corporation tasked to build and operate the national broadband network – has to record a further $1 billion in the last quarter of the 2021 financial year to hit a $4.5 billion revenue goal.
