The Lindsay, Mulcra and Wallpolla islands cover over 26,100 ha of Victorian floodplain in the Murray-Sunset National Park (Figure 5.2.6). They form part of the Chowilla Floodplains–Lindsay–Wallpolla Islands Living Murray icon site that straddles the Victoria and South Australia border. Lindsay Island, Wallpolla Island and Lake Wallawalla are recognised as nationally-important wetlands.
The wetlands and waterways in the Lindsay, Mulcra and Wallpolla islands system hold significance for Traditional Owners and their Nations. Currently there is no Registered Aboriginal Party for the region and the Mallee Catchment Management Authority involves the region's Traditional Owners in in the management of Lindsay, Mulcra and Wallpolla islands through its Aboriginal Reference Group, which includes First Peoples of the Millewa-Mallee and the Wadi Wadi and Tati Tati Traditional Owners.
