SA Government must reveal the number of children exposed to alleged sex offender in gym, says Steven Marshall SA Liberal Party politician opposition leader Steven Marshall. OPPOSITION Leader Steven Marshall has called for the State Government to reveal how many children were exposed to an alleged sex offender who operated an Adelaide gym class. It emerged last week the man had been arrested for breaching bail conditions banning him touching children after photographic evidence was presented to police. The bail conditions did not prohibit the man being in the presence of children when they were accompanied by other adults. The Government says undercover police were sent to monitor him . Mr Marshall today said hundreds of children may have been exposed to the man. " (Premier Jay) Weatherill must explain how many children - possibly hundreds - have been exposed to an alleged child-sex offender during this four-week period," Mr Marshall said. He said Education and Child Development Minister Jennifer Rankine had failed to immediately inform police about concerns, which were raised as early at May.

The Government did not respond to the Opposition's requests for numbers. A Government spokeswoman this afternoon said Gymnastics SA was notified of the charges and bail conditions but there was no evidence of a breach until the photograph was produced. Bail conditions are set by police or the courts. Police have been actively monitoring this individual's bail conditions since his arrest in 2011," the spokeswoman said.

Until a photograph was provided to police on the 29th of June, no evidence or information was provided to the Government or police that this individual was breaching bail conditions. The spokeswoman said Opposition education spokesman David Pisoni, who delivered the photograph to a police station last week and triggered the arrest, was contacted by Police Commissioner Gary Burns in a May 31 letter. No further information or evidence was provided until June 29, the spokeswoman said. "The Government has now introduced legislation to change the system as requested by the parent in their email to the minister's office," the spokeswoman said. The Opposition continues to call for sackings in the wake of the Debelle inquiry last week, which found major failings in the Education Department's response to a school sex abuse case. Parents were not promptly told of the arrest in 2010 of an after-school care provider. More: The mum who confronted the Premier The inquiry found Mr Weatherill's office received an email about the incident in 2010, when he was Education Minister, but it was not subsequently brought to his attention. It's time for Premier Weatherill to step in and assert his leadership on this issue. Since Monday, his leadership has been inadequate," Mr Marshall said. This follows on from the Debelle Report this week, which was unequivocal in its damning assessment of Mr Weatherill's advisers, (chief of staff Simon) Blewett and (former adviser Jadynne) Harvey, and their failure to advise ... of sexual misconduct in schools. However, despite agreeing with Justice Debelle's findings, Mr Weatherill has shown weak leadership and failed to act and sack his senior advisers, Mr Blewett and Mr Harvey. This is the latest blow to Mr Weatherill, who has lurched from crisis to crisis.
