The Twilights had eight consecutive national hit singles including "Needle in a Haystack" and "What's Wrong with the Way I Live". Axiom's top 10 hits were "Arkansas Grass", "Little Ray of Sunshine" and "My Baby's Gone". Little River Band had national and international chart success, including the Shorrock-penned "Emma", "Help Is on Its Way" and "Cool Change".

Shorrock was inducted into the Australian Recording Industry Association (ARIA) Hall of Fame as a solo artist in 1991 and as a member of Little River Band in 2004. In May 2001, the Australasian Performing Right Association (APRA), as part of its 75th-anniversary celebrations, named "Cool Change" as one of the APRA Top 30 Australian songs of all time.
