[5][6] Bush graduated from the Queensland Conservatorium, where he met executive producer Daley Pearson, and before Bluey, worked on series such as The Family Law and Australian Survivor.

[5] Every episode of Bluey is individually scored, a decision made by Brumm, who was inspired by the original compositions for Charlie and Lola while working on the series in the United Kingdom.

[8] Bush recorded a soundtrack for the first series of the program, titled Bluey: The Album, which was released on 22 January 2021.

The album is headlined by a three-part musical piece from "Rug Island", the namesake of the album; other notable pieces include a single titled "Octopus", featuring Australian rock band King Stingray, "Fairytale", an "'80's-inspired synth rock", "Explorers", described as a "traditional style sea shanty" modeled after Jack Russell's expedition in the titular episode, "Muffin Drive", described as a "driving rock song", and the "simple sweet" piece "Turtleboy".

[14] The soundtrack, titled Rug Island, was officially announced on 1 August 2024, with pre-orders opening the following day.
