Penalties and Sentences Act 1992

If an offender performs community service under a fine option order, the amount of the fine is to be reduced by an amount that bears to the amount of the fine, as nearly as possible, the same proportion that the number of hours of community service performed by the offender under the order bears to the number of hours of community service that the offender is required to perform under the order.

For the purposes of section 186, an amount credited against the amount of a fine under subsection (1) is taken to be payment of an amount in part satisfaction of a court order.
