The Launceston 16-year-olds are one of two dance couples - the other is from New South Wales - who will represent Australia at the World Youth Latin Dancesport Championships in Russia on October 25.

The opportunity comes just a year and a half after the pair ranked as the No. 1 Australian junior couple for Latin-American and took on the World Dance Sport Federation World Junior II Ten Dance Championships in Latvia.

October's competition will be more advanced than the 2012 one, as the best two under-21 couples from every country in the world compete instead of just under 16s. However, Henry and Charlotte are feeling quietly confident.

``Last time it was five ballroom and five Latin dances,'' Charlotte, who attends St Patrick's College, said.

``This time it's just Latin.''

Henry, a Scotch Oakburn College student, added: ``Which is good, because we're better at them. We enjoy it more, it's a little more up-beat and a lot more fun.''

Henry and Charlotte train more than 10 hours a week, but it will increase in the lead-up to the championships.

The trip will be the first time Henry and Charlotte have been to Russia and they will be accompanied by teacher and choreographer Andrew Palmer.

Palmer said the competition would be very tough.

``They [the judges] don't speak English and they are very tough on everyone,'' he said.

A number of fund-raisers will be held  to help the pair get to Russia, they are also looking for sponsors.
