Sam Clark has topped the Australian physical singles chart with his debut single 'Broken'.

The musician, who plays Ringo Brown in Neighbours, did not receive any radio support for the single and has been touring the country to promote it.

The lack of airplay meant that the song was not downloaded very often and is at number 50 in the combined downloads and physical singles chart.

"It has been disappointing and a real lesson on how the industry works," Clark told the Herald Sun. "You need radio play to reach the whole of Australia and I think radio is sometimes unwilling to take the risk to break an independent artist.

"So it's been really encouraging to break into the top 50 with little or no radio play."

Clark is hoping to release his debut album later this year.
