Fiji are drawing inspiration from their religious faith as they attempt to pull off a stunning upset against France at WIN Stadium tomorrow.

While not exactly searching for divine intervention, most of the Bati squad are deeply Christian and regularly pray together as part of their daily routine.

At the end of a two-hour tackling and ballwork session yesterday, the Fijian squad came together arm in arm to sing a hymn and to pray.

Fiji second-rower Osea Sadrau, who came to Australia three months ago to play with Queensland country club Fassifern in preparation for the World Cup, delivered an insight into the team ritual.

"It is a hymn we all sing," he said.

"We ask God to give us strength, we are praying on the Almighty to guide us."

The squad also delivered a rousing choral performance at a school during Wednesday's trip to Fijian second-rower Ashton Sims' home town of Gerringong.

Sadrau said religion was as important as anything the players learned on the football field in preparation for Saturday night's game.

It's the reason why Fiji no longer have their own version of the haka
