"11 Deciding upon the amount of the fines has its difficulties. Because the appellants have no capacity to pay, the imposition of any fine necessarily results in each serving imprisonment by way of default. It follows that, in order to ensure that the penalty fits the offending conduct, the Court must bear in mind the period which will be served by way of default.
12 Pursuant to s 15A of the Crimes Act the laws of the State concerning enforcement or recovery of fines apply to a person convicted in this State of an offence against a law of the Commonwealth until such time as the Commonwealth enacts an alternative enforcement (Aruli & Ors v Mitchell (supra)). Until January 1995 in this State, by reason of the provisions of s 155 and s 167 of the Justices Act 1902 (WA), the period of imprisonment served by an offender who had not paid his fine was determined by dividing the amount owed by $25 and rounding up the result to the nearest whole number of days. Thus, in October 1994, when imposing fines of $10,000 upon Indonesian fishermen of similar antecedents for offences similar to those in the present case, another Magistrate ordered that the offenders be imprisoned for a period not longer than 400 days until the fines were paid (see Akimin & Ors v Cooper, unreported; SCt of WA; Library No 950071; 24 February 1995). When the Fines, Penalties and Infringement Notices Enforcement Act 1994 (WA) came into operation in January 1995 the amount of the divisor specified in s 53(3) of that Act was $50. That amount applied in May 1998 when in similar circumstances another Magistrate imposed a fine of $12,500 with 250 days in default, a fine of $15,000 with 300 days in default and a fine of $20,000 with 400 days in default - sentences which were upheld by the Full Court in Aruli & Ors v Mitchell (supra). On 12 March 1999 the amount of the divisor was increased by regulation to the present figure of $150.
13 Section 58(1)(b) of the Sentencing Act 1995 (WA), which came into operation on 4 November 1996, provides that when a Magistrate imposes a fine and is satisfied that the offender is about to leave the State and that his absence would defeat or materially prejudice the operation of the Fines, Penalties and Infringement Notices Enforcement Act then, pursuant to s 58(2), the Magistrate is empowered to make an order that the offender be imprisoned until the fine is paid for a period not longer than that set by the Magistrate. Service of that period discharges the offender from the obligation to pay the fine. In this case, it was appropriate for the learned Magistrate to use the provisions of s 58, because, under the provisions of the Migration Act 1958 (Cth) s 198(5), the appellants were to be returned to Indonesia 'as soon as reasonably practicable'. On the hearing of this appeal counsel for the respondent conceded that, although no particular default period is prescribed in s 58 of the Sentencing Act, the appropriate amount of the divisor in this case is $150. Thus for the maximum fine of $27,500 the appropriate default period now would be 180 days and for fines of $25,000, which were imposed by the learned Magistrate in this case, the default period would be 167 days."
