The underlying thrust of s 16E of the Crimes Act is to ensure that periods spent in custody by a person awaiting sentence are to be taken into account when the sentence is imposed. The section provides that the first recourse will be to the law of a State or Territory making allowance for a reduction of sentence for time spent in custody. In the absence of such a provision the fall back, as provided for in s 16E(3), is that the sentencing court "must take into account any period that the person has spent in custody in relation to the offence concerned". The necessary nexus is present when the custody is "in relation to" the offence concerned reflecting an intention to permit a wide application to the provision.
[25]
The intended effect of s 63(5) of the Sentencing Act and other like provisions is to ensure that fairness applies in the sentencing process. By way of example a person may spend little or no time in custody prior to sentence and another person charged with exactly the same offence in exactly the same circumstances may spend a substantial amount of time in custody before sentence is passed. It would be unfair if the judge or magistrate called upon to impose sentence was unable to reflect the different periods in custody by making allowance for time spent in custody. To do otherwise would mean that one person would spend a significantly greater time in custody than another for the very same conduct. Provisions such as s 63(5) permit such unfairness to be avoided. They should be accorded the widest available application consistent with the wording of the provision.
[26]
The requirement of s 63(5) is that an offender must have been "in custody on account of his or her arrest for an offence" and then subsequently convicted of "that offence" and sentenced to imprisonment before back dating of the sentence is permitted. The approach to the interpretation of the section pressed by the respondent involves taking a narrow view of the terms of the section. The submission of the respondent is that the offender must be arrested and detained in custody for a particular offence and then sentenced for the very same offence before the section can have application. The effect of such an interpretation would be to limit the application of the provision to relatively rare circumstances. Such an interpretation should not be adopted.
[27]
In many cases when a person is first arrested it is for an offence which may not be precisely defined. The one course of conduct may give rise to the potential for the person to be charged with one or more of a number of offences. Further, as more information comes to hand, other, and possibly quite different, offences may be alleged against the person. For example, a person initially charged with an aggravated assault and detained in custody in respect of that offence may subsequently be charged with manslaughter in the event that the victim dies. Similarly, and conversely, a person may be charged with murder and, following further investigation and deliberation, subsequently plead guilty to an offence of manslaughter. If the respondent be correct in its submissions, in each of those cases the offender would not have been sentenced for the offence for which he was originally placed in custody and would not be entitled to the benefits provided by s 63(5) of the Sentencing Act.
[28]
In my opinion the section does not call for such a narrow and confined approach. Rather, what is called for is a consideration of the surrounding circumstances giving rise to the arrest. The expression "arrested for an offence" reflects the need for there to be an arrest for conduct which gives rise to an offence. When the person is subsequently convicted it is necessary to consider whether that conviction arises out of the same conduct which gave rise to the initial arrest and entry of the person into custody/detention. There need not be an exact identity between the offence initially identified and the offence of which the person was subsequently convicted and for which sentence is to be passed. It is sufficient that there is conformity between the conduct that led to the arrest and the conduct for which the person was ultimately sentenced to imprisonment. There does not need to be a nexus with a specific offence but rather a nexus between the conduct giving rise to the arrest and detention and the offence or offences for which the person is to be sentenced.

In my opinion that broad approach should be adopted in the application of s 63(5) of the Act to the circumstances of this case. Each appellant was detained in circumstances suggesting the commission of an offence under the Fisheries Management Act. They were each apprehended on a foreign boat found within the territorial sea of Australia and within the AFZ. The vessels were each Type 3 Indonesian vessels carrying fishing equipment. The information provided to the boarding officers was that the vessels were to be used for fishing.
[30]
The appellants were each arrested/detained under fisheries detention to provide an opportunity for the relevant officer to determine whether or not to charge the individual appellant with an offence under the Fisheries Management Act. That continued to be the case during the subsequent period of immigration detention. The only reason the appellants were detained during these periods "related to the offence concerned" to adopt the expression found in s 16E (3) of the Crimes Act.
[31]
For the purposes of s 63(5) of the Sentencing Act each appellant was taken into custody on account of his arrest for conduct which may have amounted to an offence under the Fisheries Management Act relating to the use of a foreign boat equipped for fishing in the AFZ and each was subsequently convicted of such an offence and sentenced to imprisonment. In those circumstances, in my view, pursuant to s 63(5) of the Sentencing Act the court may order that such imprisonment shall be regarded as having commenced on the day on which the offender was arrested or on any other day between that day and the day on which the court passes sentence.
