The prosecution claims Peter James Rooks, 50, now of Werribee, was aged between 23 and 37 when the offences are alleged to have occurred.

The charges relate to three alleged victims — who were all young girls at the time they were allegedly assaulted.

Mr Rooks has denied all charges and claims the alleged incidents never happened.

His barrister yesterday told a jury that the outcome of the case would come down to the jury’s assessment of the three complainants’ reliability and credibility and the timing of their complaints to police.

The prosecution yesterday detailed the circumstances in which it is alleged each of the 13 offences took place.

The trial before Judge Mark Gamble is scheduled to take weeks to complete and will continue today.
