41 In this case, as Wallwork J has pointed out, there was material in the applicant's criminal history which was a cause for deep concern as to his future offending. That concern was registered by the learned sentencing Judge who reviewed that history and compared the previous serious offences with those for which he was to sentence the applicant. As has been seen, this latest group of offences committed on the night of 16 and 17 January 1998 when the applicant was aged 25 years resulted in the imposition on 16 June 1998 of sentences aggregating 12 years imprisonment, a term which is not now contended to be excessive, but which was imposed without eligibility for parole, thereby resulting in the applicant being required to serve a period of at least 8 years. Therefore, the question in terms of s 98 was whether, when the applicant came to be released at the age of 33 years, he would continue to be such a danger to society as to warrant the exercise of the discretion to order his indefinite imprisonment.
