Although Australia won World Cups in 1991 and 1999, they have struggled on the field since reaching the final in 2015 and are currently seventh in the World Rugby rankings.
Host France, Six Nations champions Ireland, world champions South Africa and New Zealand are the top teams in the world at the moment and most pundits would pick one of them to raise the Webb Ellis Trophy in Paris on October 28th.
All four of those teams are on the same side of the draw and Smith, one of the most respected coaches in the game, thinks that might create an opportunity for teams like England, Wales and Australia who have underperformed in recent years.
"Eddie's going to get a lot of players back that Dave Rennie never had because of injury or overseas," he told the All Blacks podcast.
"He always gets an impact anyway, most new coaches do, and I would say they will be more of a danger than people expect. So that's going to be an interesting one to watch."
New Zealand were short of their own high standards last season under Ian Foster, losing a home series to Ireland and a home test to Argentina for the first time in the Rugby Championship.
New Zealand Rugby have already anointed Scott Robertson as Foster's successor after the World Cup and Smith thinks that may play to the All Blacks' advantage in France.
"To some extent, the pressure is off Fozzie," he said.
"He can now say what he wants and pick who he wants and I think the country will support it. There will be no consequences afterward, so I think he'll give it heaps.
"They've got all the coaching and mental skills ability that you need and they're going to pick a strong team.
"I've got every confidence that they're going to be tough. The All Blacks are always tough to beat but they are going to be tough."
