It has been introduced into many other areas probably because of its reputation for killing snakes. In December 1891, the Western Australian parliament included 'Laughing Jackass' in the schedule of strictly preserved Australian native birds in the Game Bill, moved by Horace Sholl, member for North District. He described it as native of the North West. His nomination is, therefore, certainly a reference to the blue-winged kookaburra ("Dacelo leachii"), not the laughing kookaburra ("Dacelo novaeguineae"). "The Game Act, 1892" (Western Australia), "An Act to provide for the preservation of imported birds and animals, and of native game," provided that proclaimed Australian native birds and animals listed in the First Schedule of the Act could be declared protected from taking. Laughing Jackass was one of 23 Australian native bird species named in the schedule. Laughing kookaburras from Eastern States were released near Mullewa in around 1896 and over the following decade hundreds of birds were imported from Victoria and released around Perth. By 1912 breeding populations had been established in a number of areas. The present range in Western Australia is southwest of a line joining Geraldton on the west coast and Hopetoun on the south coast. In Tasmania the laughing kookaburra was introduced at several locations beginning in 1906. It now mainly occurs northeast of a line joining Huonville, Lake Rowallan, Waratah and Marrawah. It was introduced on Flinders Island in around 1940, where it is now widespread, and on Kangaroo Island in 1926.
