There is solid confirmation of a proceeding with decrease, even at the best-known site close Katherine in the Northern Territory. Substantial numbers are reared in imprisonment, especially in Australia. In the state of South Australia, National Parks & Wildlife Department license returns in the late 1990s demonstrated that in excess of 13,000 Gouldian finches were being kept by aviculturists. In the event that extrapolated to an extensive figure this would bring about an aggregate of in excess of 100,000 winged creatures. In 1992, it was delegated "imperiled in the wild" under IUCN's criteria C2ai. This was on account of the practical populace size was evaluated to be short of what 2,500 developed people, no lasting subpopulation was known to contain more than 250 full grown people, and that a proceeding with decay was seen in the quantity of adult people. It is at present subject to a preservation program.
