Through late 2016 and the first half of 2017, the Queensland Redistribution Commission undertook a major review of the state’s electoral boundaries. The Electoral Act was amended before the redistribution to increase the size of the Legislative Assembly from 89 to 93 seats, and boundaries were drawn to ensure all 93 electorates had enrolment within the permitted 10% variation from the state enrolment. The Act permitted four electorates larger than 100,000 square kilometres (Cook, Gregory, Traeger, Warrego) to have enrolment below the lower limit of 10% variation.
The former electorate of Mount Isa has been renamed Traeger in honour of Alfred Hermann Traeger due to his contribution to those living in remote and rural areas. Born in 1895, he invented pedal-powered radio which was a vital resource to the Royal Australian Flying Doctor Service, but also revolutionary for Queenslanders living far apart.
