18 Each of the five charges the subject of ground 1 is a charge of sexual penetration of a child under 16 years. The circumstances in relation to each of these charges is set out above. The objective seriousness of each charge cannot be denied. In our view, the sentences imposed in relation to these charges, and the orders for cumulation in respect of them, were lenient. Looking at the circumstances of each charge, the circumstances of the appellant (including the appellant's previous good character, the appellant's previous good work history, the appellant's early plea of guilty, the appellant's degree of remorse and the appellant's willingness to undergo appropriate treatment) and the matters in mitigation referred to in the learned sentencing judge's considered and careful reasons for sentence, we are not persuaded that any different sentence should be imposed on charges 2, 3, 6, 7 and 9. Similarly, we are not satisfied that any different orders for cumulation should be made in respect of these charges.
