While the national jobless rate is steady at 5.7 per cent, South Australia has recorded a jump in the latest month.
The unemployment rate has risen to 6.6 per cent seasonally adjusted, from 6 per cent in September.
The Opposition said SA had the highest jobless rate of all the mainland states.
Employment Minister Grace Portolesi said SA, New South Wales and Victoria all recorded jobless rises for October.
"The figures released today highlight the importance of continued State Government investment to support jobs," she said.
"[They] highlight the importance of continued support to key South Australian industries like those in the automotive and agricultural sectors by all levels of government.
"It is critical that all levels of government commit to supporting industries and working in partnership to ensure their future."
