Nurses are under pressure because doctor services have dropped at Bunbury Regional Prison in WA and there has been no increase in staff numbers to go with the rising inmate population, a report has found. Acting Inspector of Custodial Services Andrew Harvey said most services are under pressure and backlogs are too common. The state government announced in December the prison would house an additional 160 prisoners, with a new double-bunked accommodation unit inside the main jail plus the re-opening of an unused minimum security section.
