The federal government has unveiled its east coast gas reservation policy which will require gas companies to set aside 20 per cent of their exports for the domestic market from July next year.

The government says the policy will "drive down" prices and ensure Australia is no longer "hostage" to international markets following soaring global gas prices in the wake of the war in Iran.

US Secretary of State Marco Rubio has met with Pope Leo at the Vatican, in what has been viewed as a bid by the White House to ease tensions between the pontiff and President Donald Trump.

The meeting comes just days after President Trump unleashed new criticism of the first American pope, claiming his views on foreign policy were "endangering" Catholics and that the Pope was quote "fine" with Iran having a nuclear weapon – Pope Leo quickly dismissed this as untrue.

The Vatican has issued a statement saying the two had "exchanged views" on the world situation and spoke about "the ​need to work tirelessly in favour of peace."
