The state government has held confidential talks with commercial operators and organisations that have Christian mission statements, as part of a controversial outsourcing proposal for Sport and Recreation Centres used for thousands of school camps every year.

Leaked documents show government-appointed consultants have held "market sounding" discussions with eight organisations, including NGOs, the multinational PGL group and organisations linked to the Christian Community Churches of Australia and the Crusader Union of Australia.

Labor has questioned the suitability of Christian groups to deliver services at the camps, which are used by 70,000 students each year, many from public schools.

The Crusader Union's website says it has "proclaimed the gospel to school students since 1930". The group did not return a request for comment by deadline.
