The Aboriginal community of Imaṉpa was formed near Mount Ebenezer in 1978. At Angas Downs, Arthur Liddle and his family continued to raise cattle during the 1980s and 1990s. As with many pastoral enterprises during this time, Angas Downs struggled with money. The property was eventually bought by the nearby Imaṉpa community, on 2 May 1994. Since then, it has been owned by the Imanpa Development Association, and managed by their company Lisanote Pty. Ltd. Angas Downs was declared an Indigenous Protected Area in 2009. The property still holds 300–400 cattle, which are restricted to a 266 km enclosure in the southeast.
