The offender, Hussein Ali Kelkas, was found guilty of three charges of sexually assaulting two complainants.
The court considered victim impact statements, the offender's background, and a sexual behaviours assessment.
Aggravating factors included the violent nature of the assaults, anal penetration, ejaculation without a condom, and the offender's criminal record.
Mitigating factors included family support and an apology to the court.
The court accepted a joint submission for a sentence of five and a half years of imprisonment, less 32 days for pre-sentence custody.
Ancillary orders included a mandatory DNA order, lifetime registration under the Sex Offender Information Registration Act, a lifetime weapons prohibition, and a non-communication order with the complainants.
