On 14 May 1878, Short joined the very small Queensland Police Force, training in Brisbane, before being posted to the then-most distant south-western station of Saint George.[2]
Within his first few weeks, Short's first arrest was a naked man with a firearm terrifying the people at a property. After a clever ruse, the man was captured. The firearm was later discharged, and burst because it had been loaded almost to the muzzle.[3] Together with Trooper Power, he later went to Booligar, on the Narran River to establish a camp with rumours of the Ned Kelly gang of bushrangers working towards the area from New South Wales.[2] As a competent horseman, he also covered great distances after stock thieves.[3]
After serving more areas in the Maranoa, including Marburg,[4] he was promoted on 1 January 1884 as acting-sergeant, soon rising to senior sergeant.[2] In 1898 Short became the officer in charge of the South Brisbane police station, and in January 1901,[5] the senior sergeant in charge of the Criminal Investigation Branch. He then became a sub-inspector third-class in January 1904,[6][7] until transferred at his own request to Maryborough in 1910, then onto Toowoomba for seven months.[2][8] A promotion to senior inspector saw Short move to Petrie Terrace Police Depot, to overview the Brisbane district.[2] In January 1917, he became the senior inspector for the State for criminal investigation.[9]
Announced in December 1920,[10] on 16 January 1921 on the retirement of Commissioner Urquhart who became the Administrator of the Northern Territory, Chief Inspector Short was appointed to the rank of commissioner for a period of three years. He was the first constable and Queensland-born officer to become commissioner.[3]
As a horse lover and judge of blood lines, as one of his actions as Commissioner, he sought to improve the Queensland police horse at the police horse breeding station of Rewan, at Springsure.[1]
During his tenure he condensed the number of police districts from twelve to ten, and oversaw changes to the Police Act in regard to improving police pensions and family allowances. In 1924 Short witnessed legislation which provided a system of appeal against promotions to members of the Queensland Police Union up to and including the rank of senior sergeant.[11]
With 46.5 years in the force, Short announced his retirement in early December 1924.[12] He remained as commissioner to 16 January 1925, reaching 65 years-of-age, when he retired with an unblemished record on £700 per annum.[12][13]
