Big Splash is a waterpark in Canberra, Australia. It is located in the suburb of Macquarie and is the only waterpark in Canberra. It originally opened with a 50-metre (160 ft) Pool with a kids pool at the end of it in the late 1960s. When the pool opened it was Government-owned and known as Macquarie Swimming pool, also often referred to as Jammo Pool. The slides were introduced in the early 1980s. The pool was sold from government ownership. It was bought by a family and then later sold to the Watkins family in the 1990s. The facility is closed over winter and is open from November to March.
