Sri Ranga Sabha

 In June 1999, Champa and Chandrani Buddhipala founded Sri Ranga Sabha Incorporated - the first ever Sri Lankan dramatic association in Australia. Sri Ranga Sabha pioneered the importation of Sinhalese dramas from Sri Lanka to Australia. Champa has written, directed and produced four full-feature stage dramas with Sri Lankan and Australian combined casts, namely Krishna (2002) based on Hindu scripture Srimad Bhagawatham, Daskon (2008) based on Sri Lankan history and a royal love triangle, and Meththara (2012) highlighting the Buddhist concept of compassion. On 22 July 2003, Krishna was featured on Asia Pacific Focus on ABC television channel, making Krishna the only Sri Lankan dramatic event featured on Australian television to date. Meththara won three awards and four nominations at the State Drama Festival in Sri Lanka in 2015. 

 In 2016, Champa Buddhipala translated the Pulitzer Prize winning renowned drama by Tennessee Williams, A Streetcar Named Desire. His translated stageplay, titled Ashawe Veedi-Riya, was nominated for Best Translation at the Sri Lankan State Literary Award Festival 2017. The translated play has now been published as a book. It is the first official Sinhalese translation of A Streetcar Named Desire, with full rights provided through permission of Georges Borchardt Inc. New York, USA. Sri Lankan drama students previously never had access to this play, and now his text is studied by the students of the Drama Faculty at the University of the Visual and Performing Arts, Sri Lanka.
