The Sydney Swans star, who has experienced racial vilification on the football field, posted a copy of changes to the Racial Discrimination Act on social media on Wednesday, asking what other people made of the so-called freedom-of-speech amendments.

''It means it's open season for bigots. Even the 'good faith' provision is going,'' replied Liz Burke, a follower of Goodes on Twitter.

Goodes responded: ''Yes it's something you have to keep reading to fully believe isn't it. Hmmm.''

He also expressed concern that the new section four of the draft bill was so broad as to be a ''loophole'' for other protections, including provisions against ''intimidation and vilification''.

The Human Rights Law Centre has also strongly criticised section four.

Executive director Hugh de Kretser said: ''Our biggest concern is the gaping hole introduced by the public discourse exemption.''
