30 The appellant's offending is in a significantly more serious category than Gozenton and Sherwood. On the other hand, the appellant's offences and their circumstances are in a less serious category than PP, Lawrence, S v The Queen and Lippiatt (although in the last case the offender pleaded guilty). It is significant in this case that the family connection was not such as to itself give rise to a relationship of trust in the accepted sense. Further, this is not a case where the offences charged were a representative sample of a wider course of conduct. That is not to minimise the seriousness and gravity of the offences that were committed intermittently over a lengthy period and involved "grooming". However, having regard to the circumstances of the offences, the standards of sentencing customarily observed in relation to more serious offences with significantly higher penalties and the appellant's personal circumstances, I am satisfied that the sentence of 9 years (reduced to 6 years) is significantly above the range of a sound sentencing discretion. Accordingly, there being an error, the appellant is entitled to have this Court exercise its own sentencing discretion: House v The King [1936] HCA 40; (1936) 55 CLR 499 at 505.
