After spending months hatching their plans to win the Rugby World Cup, Australia's coaching staff appear to have 'accidentally' revealed some of their secrets on the eve of Sunday morning's final against New Zealand.

While the Wallabies coaching staff have remained tight-lipped about their tactics in the lead-up to and during the World Cup, they could have let their guard down at the worst possible time.

During Friday's final training run at Twickenham, the Australian head coach Michael Cheika and the team's forwards coach Mario Ledesma were each holding pieces of paper with neatly typed notes.

Copies of the sheets were magnified then published by British media, revealing Australia's apparent plans to target specific New Zealand players.

The printed notes included instructions to "rattle" New Zealand number eight Kieran Read at kickoffs and "expose" the All Blacks wingers Nehe Milner-Skudder and Julian Savea with high kicks.

However, the rivalry between the All Blacks and Wallabies is so great that the 'leaked' papers could be a deliberate ploy with Cheika playing mind games with his opponents.

The All Blacks have been careful about their own tactical plans since a UK journalist gained access to their dressing room before a Test against England in 2013 and reported on the messages on their whiteboard, with coach Steve Hansen saying New Zealand was now "a bit smarter" about security.

Hansen is predicting a more spectacular Rugby World Cup final than when the All Blacks claimed the crown four years ago.

World Cup play-off games are traditionally tight affairs and the finals are notoriously tense, no more so than the 2011 final when hosts New Zealand squeaked past France 8-7 at Eden Park to end their title drought.

Hansen believes the style of game adopted this year by his team and Australia lends itself towards a vibrant spectacle at Twickenham.

"The pressure will be on both teams, but I don't think that will inhibit either one of them," said Hansen, who was an assistant coach to Graham Henry at the 2011 World Cup.

"The Australian team will play to their strengths, and we will play to ours. Given the conditions are OK, I think we will see some running rugby. Whether that results in a lot of tries depends on how good the defences are."

Hansen says he has left no stone unturned in the preparation and is delighted by his team's unbeaten run at the tournament.

"We are looking forward to tomorrow immensely. I know, win or lose, we will put in a performance we will be proud of," he said.

"If that's good enough to win, great. If not, we will look at ourselves and ask what we need to do better.

"But we won't be inhibited by the occasion. This group is in a good place and excited about what's coming, and we've got a bit of talent, so if we play well, the result might come our way."
