After prosecutors unsuccessfully moved for the court to be closed, it was heard the allegations levelled against the man dated back four to six years.
His lawyer David Jones, in applying for bail, characterised the crown case as involving “some grooming” of two complainants when he was in a relationship, which has since ended, with their mother.
He also said the prosecution relied strongly on evidence drawn from a “largely untested” technology in their case against the policeman but didn’t specify exactly what it was.
“There are serious allegations made against him,” Magistrate Elizabeth Hall noted.
Police prosecutor Josh Kelly objected to bail on the basis that he may interfere with witnesses and given the seriousness of the charges.
The man, who cannot be named for legal reasons, has been suspended from the police service while the allegations against him are dealt with. The bail hearing will return to court on October 12.
