Online gamers are heavily to blame for slow internet, according to the head of the National Broadband Network (NBN).
Congestion on the wireless network during peak times has resulted in the NBN Co "evaluating" options, including restricting downloads.
And the chief drainer of internet during peak times is largely attributed to gamers.
NBN Co chief executive Bill Morrow has said that heavy users which are the likely target of a fair use policy were gamers.
"While people are gaming it is a high bandwidth requirement that is a steady streaming process," he said.
"This is where you can do things, to where you can traffic shape — where you say, 'no, no, no, we can only offer you service when you're not impacting somebody else'."
However, Mr Morrow later rejected claims that gamers were the sole problem.
According to research by the Australian Communications and Media Authority in 2016, increases in data transfers are largely due to video content downloading.
There is currently already a fair use policy in place regarding NBN satellite users, limiting peak-hour data consumption to 75 gigabytes in any four-week period.
