Home Affairs Minister Peter Dutton has ramped up the pressure on websites spreading "evil" hate messages after more than 20 people were killed in a suspected terrorist attack in the US.
American authorities have cited a manifesto posted online and attributed to suspect Patrick Crusius, 21, as evidence the bloodshed in El Paso, Texas was racially motivated.
The four-page statement posted on online message board 8chan, which is often used by extremists, called the attack "a response to the Hispanic invasion of Texas".
Mr Dutton believes companies must do more to get hateful content pulled off the internet.
