Serena and Venus. Pippa and Kate. And perhaps the Kardashians, sort of…we prefer the Campbell sisters. Between them Cate and Bronte Campbell have won 64 International Swimming medals including 11 Olympic, 23 World Championships titles and 16 Commonwealth games medals.

They are the first Australian sisters ever to compete within the same swimming event at an Olympics and are both current World Record holders in the 4x 00m freestyle relay.

Now they’ve towelled down and extended their success out of the pool, by writing a new book together, called Sister Secrets.
