Scott was named on Monday as skipper in the fours and second in the triples for the Australian squad to compete at the world championships from May 26 to June 7 on the Gold Coast.

The 29-year-old has been a mainstay of the two sides, who are also the reigning Commonwealth Games champions.

Carla Krizanic is unavailable for the world titles because of pregnancy and she has been replaced by Ellen Ryan, who will play lead for the fours and triples.

Rebecca Van Asch joins Ryan and Scott in the triples. Pairs competitor Lynsey Clarke is their teammate in the fours.

Scott said Australia would lose nothing with the addition of Ryan.

"She was part of the Trans Tasman team that recently played and we came away with the win there, so I think it's just as solid," Scott said.

Australia will be favourites for both titles again and Scott will aim for three consecutive triples crowns.

"Everyone goes out to beat Australia, for some reason, and we walk out in every game with massive targets on our backs, so it's no different," Scott said.

"We've just got to treat every game as a new game and don't underestimate any opposition."

The rest of the Australian squad is: Kelsey Cottrell, Aaron Wilson, Corey Wedlock, Barrie Lester, Aaron Teys and Aron Sherriff.
