Indigenous leader Noel Pearson says he is concerned Queensland's child protection system is corrupt.

His comments follow claims that Queensland Government ministers ordered child safety officers not to tell police about child sex abuse and neglect cases on Cape York.

The claims are contained in today's The Australian newspaper, which says it has obtained a record of an interview between Crime and Misconduct Commission-led investigators and a senior police officer.

In it the officer says police were aware of "numerous child protection issues through the Cape we hadn't been advised of."

Responding to the claims, Mr Pearson told ABC Radio's AM program that any cases of sexually transmitted diseases in children should be automatically referred to police.

"I'm extremely alarmed to find out that one of the central problems of the old system, which was that people in officialdom instruct people on the ground not to provide information, particularly information to the police authorities.. haven't been fixed," he said.

"The idea that we still have a system where there's some kind of political instruction not to expose things and not report things to the appropriate authorities, particularly the police, is extremely concerning and must be thoroughly investigated.

"Because if there's any hesitation on the part of either health workers or teachers or child safety officers on the ground, if there's any hesitation about their function, that is that they should be reporting all concerns to the police, then we have a corrupted system."
