In December 2009, in the context of a Cabinet reshuffle, Carcasses left the Opposition and joined Natapei's government, becoming Minister of Internal Affairs. In his latter capacity, he argued that unemployment in Vanuatu should be addressed by encouraging young people to return to agricultural work in their native rural areas, and produce their own food, rather than move to Port Vila where they would often struggle to find a job. He joined the Cabinet as the leader of an informal "Alliance" of MPs from a variety of small parties, and three independent MPs.
