Queensland's unemployment rate continues to rise, reaching its highest level since June 2003.

The latest statistics from the Australian Bureau of Statistics showed Queensland's seasonally adjusted rate increased from 6.3 per cent in June to 6.8 per cent in July.

Queensland suffered the biggest loss of jobs in the country last month.

Trend figures, the raw data government's prefer to rely on, also increased much more marginally from 6.4 per cent in June to 6.5 per cent in July.

But Queensland's result was in line with the nation and other states.
