The federal Coalition's cabinet is the most powerful collection of Catholics ever assembled in Australia, with almost half its 19 minister being members of that faith, nearly double the proportion of Catholics in the general population.

The Prime Minister, Treasurer and finance, trade, communications, education, agriculture and social services ministers are Catholics, and at least four others belong to other Christian denominations.

Asked by Fairfax Media about their Easter plans, half the Abbott cabinet confirmed they would be attending church. And while almost a quarter of the population ticked "no religion" in the 2011 census, nobody in the Coalition cabinet would admit to being an atheist.

Agriculture Minister Barnaby Joyce, a Catholic who plans to attend four church services over the weekend, said: "I'm no saint but I try to go to all the services that are part of the Easter ritual."
