A spin-off from Crawford Productions' Matlock Police, Solo One transferred motorcycle officer Gary Hogan from the fictional town of Matlock to the real town of Emerald in the Dandenong Ranges, where the program was filmed on location.
The program, an attempt to capitalise on Gary Hogan's popularity with child viewers of Matlock Police and less adult in focus than its predecessor, wasn't renewed for a second season, after Cronin moved on to Crawford's war-time drama, The Sullivans. Don Storey, in his Classic Australian Television, notes that the program 'was very successful and received much critical acclaim', but Moran, in his Guide to Australian TV Series, counters that 'Cronin, though lovable both to Crawford's and the Victorian Police, who were advisors on the series, was far too long in the tooth to be playing this kind of role'.
