BOCSAR tracked the offending patterns of all 26,472 offenders born between 1986 and 1990 (inclusive) that had at least one violent offence proved against them before 31 December 2014. The mean follow-up time was 6.35 years but the longest follow-up period was 21 years. In the median case, after 20 years, an estimated 77 per cent had not been convicted of a further violent offence.

BOCSAR found, however, that the risk of violent re-offending varied greatly across different offender groups (see table 5). Higher rates of violent offending were found for younger offenders, offenders whose first proven offence occurred when they were young, Indigenous offenders and offenders convicted of any of the following offences: justice procedure offences (e.g. breach of bond), malicious damage to property or theft.

Interestingly, after controlling for other factors, offenders convicted of domestic violence offences were no more likely to be reconvicted of another violent offence than offenders convicted of non-domestic violence offences.

Commenting on the findings the director of BOCSAR, Dr Don Weatherburn, said they highlighted the dangers associated with stereotyping all violent offenders as dangerous recidivists.

„There is a small group of violent offenders who keep on committing violent offences but the majority desist after just one offence.”

„Those who do continue don’t tend to specialise in violent offending. They have long criminal histories and convictions for a wide variety of different offences.”
