Superstar Charlotte Caslick has hinted at a few tactical surprises from Australia's Olympic and world champions at rugby's Sydney Sevens - if her teammates can remember them.
Consistency and focus were hallmarks of the team's stunning successes last year.
However, with pressure to remain at the top to be tested at the inaugural Sydney women's event starting on Friday - round two of the six-round women's world series - Caslick said the side had been investigating ways to stay ahead of the opposition.
"We always try to keep ahead of all the trends of the game," Caslick said.
"I guess our core skills - passing and all of that - is the biggest part of our game that we pride ourselves on. We're trying to make sure that we're still ahead in that regard.
"But there's always new defence policies that we can implement and practice. There's always new things that we can try and see what works best for our team."
The Australians, captained by Sharni Williams and featuring the core of the side that claimed the inaugural Olympic gold medal, will play Fiji, Brazil and Ireland in their Pool B games.
Assuming they progress, they may get to seek revenge against New Zealand, who beat Australia 17-5 in the final of the opening round in Dubai in December.
"I think New Zealand are having a very good patch of rugby at the moment. We always love playing them, it's always such a good contest," Caslick said.
Coach Tim Walsh said his players had analysed their potential opponents but would attempt to take the initiative at every turn.
"Every year, every competition, we try and keep the opposition guessing with different variations or with different plays," Walsh said.
"But there's no secret to playing. It's just the odd call or the odd different play that'll put a bit of a spanner in the works and keep opposition guessing. There will be a couple of those, if they remember them! I hope they do!"
The women's tournament concludes on Saturday, while the two-day men's tournament finishes on Sunday.
The inexperienced Australian men's side received a big boost earlier this week with the inclusion of captain Sam Myers after he suffered a corked shoulder at the Wellington Sevens, where the team finished 10th.
South Africa beat Fiji in the final at Wellington, which was the fourth round of the 10-round men's competition. Australia play Scotland, Papua New Guinea and New Zealand in their pool clashes in Sydney.
New Zealand pipped the Australians 27-24 in the final of last year's Sydney Sevens tournament.
