ALMOST 15,000 people have joined an Atheist Foundation of Australia push to mark "no religion" on the coming census.
The foundation has begun unveiling billboards urging people to take the religion out of politics.
Thousands have also vowed to mark "no religion" in a Facebook campaign.
AFA president David Nicholls said many people selected the religion they were born into, despite not being religious.
He said the transfer of taxpayers' money to religious organisations was justified on the basis of the census results.
More than 70,000 people declared themselves Jedi order members in 2001 but Mr Nicholls warned such an answer was now marked as no response.
