NSW cult leader William "Little Pebble" Kamm wants a court to consider letting him return to his "holy" land or remove his ankle monitor after having a stroke.
The convicted child sex offender, who now calls himself William Costellia, founded the Order of Saint Charbel near Nowra in the 1980s and preached a doomsday Christian message.
His followers handed over wives and daughters to help him rebuild humanity after the apocalypse and he has reportedly fathered more than 20 children.
He spent nine years in jail for having sex with two teenage girls before being paroled in November 2014.
In 2016 he submitted to release conditions that include wearing electronic monitoring equipment, telling authorities his schedule in advance, living with his wife at a unit in Sydney, abiding by a 10pm curfew, remaining in NSW and staying away from teenage girls.
