The Australian duo will up their intensity in the gold medal 2km race as they seek to avenge missing a medal at the 2007 world titles.

Cook and Crow booked their place in the final after showing promising signs in the semi-final, finishing second to the United States.

They have been together for the past four years and, while admitting they still had to improve, Canberra's Cook said they were determined to break into the world's top three.

''At worst we want to take home a bronze medal,'' Cook said yesterday.

''We go out to win every race and I know that if we put in our best performance we can definitely take home the gold.

''And if we don't finish in the top three then we probably haven't had our best race and we will be disappointed.''Cook and Crow matched the United States crew for the first 1500m of the race before falling off the pace to finish a length behind the winners.

While most international teams have been competing on the World Cup circuit, Cook and Crow chose to remain in Australia for training.

And while they are yet to win a race in Poland, Cook said she and Crow had a few ''secret weapons'' still up their sleeves.

''We're still trying to find consistency in our performances and we know there are things we can work on,'' Cook said.

''When the Americans broke away we knew we would have answered, but we chose to save a bit in the tank.

''Our semi-final was just about a solid and consistent race while we've got some big changes of speed that I think are going to put us in a good spot in the final.''

Meanwhile, Australian rowing's odd couple Toowoomba duo Sally Kehoe and Pippa Savage have positioned themselves to become the most unlikely of world champions.

While the double sculls pair hail from the same small Darling Downs city, they only became crewmates for the first time in May.
