Two liberal parliamentarians met with far-right leader Neil Erikson at a rally in support of white South African farmers in Perth last year.
Andrew Hastie and Ian Goodenough held a "brief meeting" with the convicted felon who defends far-right opinions online and was banned from Twitter and Facebook.
Goodenough, who holds Moore's safe spot in the northern suburbs of Perth, said Erikson and some of his supporters met with the two members of Parliament at the Forrest Chase rally last April and spoke directly to Hastie.
"We were at a demonstration by the South African migrants and he came and there was a talk," Goodenough told Guardian Australia.
"It was a very brief meeting of what I saw, two to three minutes."
Goodenough said he did not know the man's identity and "his small group" of followers until he was recently appointed by an official. He said he believed Erikson or one of his supporters had registered the meeting.
Hastie was asked on Tuesday whether he has ever had "secret" meetings with Erikson, who is widely considered one of the leaders of the far right movement in Australia.
The Canning Member of Parliament said he would not respond to "defamatory" questions.
Erikson and Cottrell were among the three members of the United Patriots Front who were convicted of inciting contempt for Muslims after staging a protest decapitation against plans to build a mosque in Bendigo.
The three men were fined $ 2,000.
Erikson was also among those who attacked the boy who broke an egg in Fraser Anning's head in protest of his far-right views at a March press conference. One teenager was charged with assault in connection with this incident.
