 The noisy miner is endemic to eastern and south @-@ eastern Australia , occupying a broad arc from Far North Queensland where there are scattered populations , to New South Wales where it is widespread and common from the coast to a line from Angledool to Balranald , through Victoria into south @-@ eastern South Australia , and eastern Tasmania . Its range in South Australia has been steadily expanding since it was first recorded near Adelaide in the early 1890s . It is sedentary over its entire range . The noisy miner is territorial , and the territory of a colony is aggressively defended — which has led to a significant reduction in avian diversity in areas occupied by the noisy miner , with smaller species excluded .
