He was a senior research fellow (2013–2017) in sonification in the Emerging Audio Research Group at Fraunhofer Society (the International Audio Laboratories of Fraunhofer-Institut für Integrierte Schaltungen IIS) in Erlangen, Germany, undertaking research in the application of sound in the diagnosis of sleep aponea and the sonification of large networks. He is currently a professor in the Audio Arts and Acoustics Department at Columbia College Chicago and an adjunct senior research fellow in the School of Music, the Australian National University.

His book: Sonification design: From data to intelligible soundfields is published by Springer in their Human–Computer Interaction Series.

Worrall has been a regional editor for Organised Sound (Cambridge University Press) since 1996. Since 2000 he has worked as an academic and freelance composer, experimental artist (e.g. The Twins) and researcher with a growing interest in the human voice, both acoustic and synthetic (e.g. algorithmic poems such as A doing resounds and the extended text-to-speech work (e.g. I am on the net through an interface different from the one which you use when you do, a homage to Alvin Lucier,) as well as the continued development of PIPES works such as the large-scale collaborative Alien Garden.

Worrall has won various composition and research awards and has held artist-in-residence and visiting fellowship positions in universities in Australia, France, Spain, the US and in the UK, where most notably he was Leverhulme Fellow in the Music Department at the University of York in 1996. He was a founding member of the Music Council of Australia, now Music Australia, which made him an Honorary Life Member in 2009, the Electronic Music Foundation and has served on a number of organisational boards, including the Australia Council's Music and Innovative Projects (later Mixed Media) Boards, the Australian Music Centre, where he is a represented artist, and as president in 1998/1999 of the Australasian Computer Music Association. He has been and a board member of the International Community for Auditory Display (ICAD) since 2010 and their elected President 2016–2019.

In 1986 he was appointed director of the Electronic Music Studios at the Canberra School of Music. He established and became the foundation head of the Australian Centre for the Arts and Technology (ACAT) at the Australian National University in 1989, a position he held for over a decade. During that time, ACAT offered the first Australian postgraduate degrees in multimedia: considered a sub-discipline of the Electronic Arts, along with electroacoustic music and computer animation. Worrall's output from this period is dominated by electroacoustic (e.g. Harmonie du Soir), polymedia (e.g. Cords), computer animation soundtracks (e.g. En Passant Marcel Duchamp) as well as his continued interest in combining acoustic instruments with electroacoustics (e.g. Air).

Worrall was appointed to the Faculty of Music at the University of Melbourne in 1979 to teach musical composition and undertake research in computer music. In addition to composition, orchestration, twentieth-century techniques and free improvisation, in 1981, before the advent of the personal computer, he designed and taught the first undergraduate course in computer music in Australia using a mainframe computer, and MusicC (a development of CMusic) and Gary Lee Nelson's Music Programming Library (written in APL). His music from this period includes the Albert H. Maggs Award commission Images for Two Pianos and the Seymour Group commissioned Glass Games for ensemble and computer–generated tape – the first Australian work in this format. Other notable works from this period include Mixtures and re-collections and ...with fish scales scattered....
