Neighbours actor Sam Clark has topped an Australian music chart with his debut single, Broken.

The star, who plays Ringo Brown in the soap, achieved the top spot despite lack of airplay on radio stations.

He reached No 1 on the Australian Record Industry Association (ARIA) physical singles chart, which is calculated on CD sales rather than digital downloads.

The 22-year-old Neighbours star, who toured schools and shopping centres down under, admitted he was disappointed not to get radio support.

“It has been disappointing and a real lesson on how the industry works,” he told the Herald Sun. “So it’s been really encouraging to break into the top 50 with little or no radio play.”

Sam, who released his single independently, hopes to release an album later this year.
