By comparison, Australia Post told Senate estimates that 0.8% of its employees were paid more than $200,000 per annum.

On its website, the NBN Co has a long list of comments made by Morrow to the Sanate estimates. However, there is no mention of the salaries paid to staff.
In its latest results, the company announced a loss of $3.3 billion for the nine months to March 2018.
This was up by $1.2 billion, with the loss in the nine months for the previous financial year being $2.7 billion.
The report cited an NBN Co spokesman as defending the salaries paid out, saying: "“To meet our operational goals, NBN Co has recruited highly experienced engineers, project managers, IT engineers, business managers, lawyers, marketers, human resources, and account executives."
