Eddie Jones warned "I'm not the messiah" after starting his second spell as Australia head coach but believes they can win the Rugby World Cup.

Jones was sensationally appointed as Wallabies boss in early January after being sacked as England head coach.

He replaced Dave Rennie eight months before the World Cup starts in France, taking up a role he previously held between 2001 and 2005.

Jones signed a deal until 2027 and started work on Sunday, a day before his 63rd birthday.

The vastly experienced Jones is aiming high, but says he has no magic wand to wave as he strives to make Australia a force again.

He said during a press conference on Tuesday: "I'm thrilled to be back home in Australia and couldn't think of a better place to come back to than here in the heart of Sydney's grassroots.

"It's imperative we win the hearts and minds of young Australians and to get them playing rugby and supporting their national teams.

"I think I made the point that I'm not the messiah, everyone's in this together. Sometimes you just need someone to beat the drum.

"And that gets everyone walking a bit faster. And maybe that's the role at the moment. But as we go forward, it's going to be about everyone working together."

Jones expects his side to show "traditional Australian digger spirit" as they will require more than talent alone to win the World Cup.

"I reckon we've got to draw a line in the sand and where we've been and work out where we want to go ... then everyone needs to roll their sleeves up," the former Japan head coach said.

"We can't do it by ourselves. We need everyone in the rugby community to find a bit more, and they can. There's plenty of people who love rugby when the Wallabies win, so we're going to win, but we need them to maybe help start it."

He added: "There's plenty of talented players, but talent doesn't win World Cups.

"What wins World Cups and wins hearts of people are teams that play with that same spirit the Ellas [Mark, Glen and Gary Ella] had, being aggressive and playing with a certain panache.

"We want to play tough. You want to win those tight games by one or two points, and that's the traditional Australian digger spirit. We want that in the team."
