Almost one-in-two Australian adults released from prison are back behind bars within two years, the Productivity Commission has found.
The latest report on justice services in Australia released on Wednesday showed recidivism rates have been slowly on the rise since 2014-15.
That financial year, 44.5 per cent of adults released were back in prison for a new offence within two years, and in 2018-19 it was 46.4 per cent.
The commission also found nearly a quarter of people discharged from community corrections orders were back under a new order or in prison within two years.
Figures show slightly fewer community corrections orders were completed in 2018-19 than 2009-10.
Inside prison, non-indigenous prisoners were being employed at a disproportionately higher rate than Aboriginal and Torres Strait Islander inmates.
Australians were also less trusting of police than they were six years ago, according to the report.
In 2018-19, 72.1 per cent of people agreed police treated people fairly and equally, down from 75.1 per cent in 2012-13.
Police in every jurisdiction except the ACT have fewer Aboriginal officers employed proportionate to the local indigenous population, while there were more female officers than in the six years before 2018-19.
More Australians were driving with a seat belt than they were five years ago, but more were caught drink-driving and speeding at least 10km/h over the limit.
Road deaths slowly dropped over the 10 years between 2009-10 and 2018-19, from 8.7 deaths per 100,000 registered vehicles to 6.2.
Policing has become expensive, with taxpayers spending $493.70 per person in 2018-19 on the service compared to $452.20 in 2012-13.
Civil courts in Australia were becoming more expensive, with fees in 2018-19 costing people nearly $3000 in 2018-19, compared to $2603 in 2014-15.
