 It is also included in the 2007 advisory list of threatened vertebrate fauna in Victoria where it is listed as vulnerable.The suspected chief threats faced by the brolga, particularly in the southern part of its range, are habitat destruction particularly spread of blue gum ("Eucalyptus globulus") into breeding habitats, the drainage of wetlands, collision with powerlines, burning and grazing regimes, spread of invasive species, and harvesting of eggs.It is more secure in the north-eastern part of its distribution range as the floodplains of Queensland are mostly unsuitable for farming and much of it is in private ownership, but development activities that change or reduce habitat diversity, especially in the Gulf Plains, can have unknown impacts on their populations.
