Safran who identified himself as "John Michael", 33, from Melbourne, to reporters joined three local men and one woman in being nailed to a wooden cross in Kapitangan town, just outside Manila. Another 25 men were crucified in Cutud town, north of the capital.
Photographs clearly identify the man as TV personality John Safran, who co-hosts a weekly comedy talk show Sunday Night Safran on ABC Radio's Triple J youth network with Catholic priest Bob Maguire.
He has a history of going to extremes in TV documentaries and an interest in obscure religious practices.
Safran, who was half-naked and wearing a long-haired wig with an improvised crown of thorns, joined the Filipinos in a procession carrying a huge wooden cross to a crucifixion site, flanked by men in Roman centurion costumes.
The crucifixions, although not formally endorsed by the Roman Catholic church, are carried out as part of religious vows in return for favours granted or in penance for sins.
