Senior Hindu leadership have been accused of fanning the flames of racial vilification and religious bigotry by sharing far-right anti-Muslim ideology.
A complaint received by the Australian Human Rights Commission accuses senior members of the Hindu Council of Australia of breaching section 18C of the Racial Discrimination Act.
The Alliance Against Islamophobia alleges council president Sai Paravastu and his wife Neelima Paravastu, the council's head of marketing and media, engaged in serious and repeated public acts of racial hatred against South Asian Muslims.
When contacted by AAP on Monday night, Mr Paravastu said he had not yet seen the complaint and did not offer comment.
He did not respond to further queries about the allegations on Tuesday morning.
The 96-page complaint seen by AAP details posts allegedly shared by Mr and Mrs Paravastu on X and Instagram from September 2024 to July 2025.
They include retweets quoting recently slain US right-wing activist Charlie Kirk and British anti-migrant firebrand Stephen Yaxley-Lennon, better known as Tommy Robinson.
"Islam is not compatible with the West. Importing millions of Muslims is suicidal," Mr Kirk said in a video shared in June by Ms Paravastu, a prolific user with more than 38,000 tweets.
The posts are alleged to "offend, insult, humiliate or intimidate Muslim people of the specified ethnicities, national origins and races in Australia" and to have "engaged in unlawful discrimination", according to the complaint.
The content had left Muslim members in Australia feeling marginalised and unwelcome in their own community, the alliance said.
"The (Hindu Council's) mission speaks of living in harmony with other religious and cultural communities," a spokesperson for the alliance, representing south Asian Muslims, said.
"Yet the behaviour we have experienced is the exact opposite.
"As Muslim members of Australia's diverse multicultural fabric, we cannot simply stand by while an organisation acts against the very principles it claims to promote."
The complaint seeks a formal public apology from the Hindu Council, offending material taken down and compensation for harm and distress caused.
Moustafa Kheir, principal Lawyer at Birchgrove Legal who is taking on the case, said the council had "unfortunately engaged in conduct that singles out Muslims in ways that are threatening and exclusionary."
The Paravastus accounts on X had been deactivated on Tuesday.
