The footage of Folau preaching to the congregation at his church was posted to the Facebook page for The Truth of Jesus Christ Church Sydney in Kenthurst as more than 50 fires burned across NSW.

Six people have died and 476 homes have been destroyed in fires throughout the state since the start of this year's bushfire season.

Folau said: "God's word says for a man and a woman to be together, one man and one woman in the covenant of marriage.

"The world, I'm speaking to Australia right now, they've come and changed this law. They've changed that law and now they've legalised same-sex marriage."

He also said of abortion, which was decriminalised in NSW in October, that "in the eyes of God it's evil, in society today it's good".

"Look how rapid, these bushfires, these droughts, all these things have come, in a short period of time. You think it's a coincidence or not? God is speaking to you guys, Australia, you need to repent.

"What you see right now in the world is only a little taste of God's judgment that's coming, it's not even a big thing."

Folau said the natural disasters were "no coincidence" and the solution was for people to "turn from their wicked ways".

Rugby Australia sacked Folau after he wrote a post on Instagram saying drunks, homosexuals, adulterers, liars, fornicators, thieves, atheists and idolators would go to hell unless they repented.
