Suspended Queensland chief scientist Suzanne Miller has been charged with 31 additional fraud offences, with corruption authorities alleging she spent more $30,000 on a government corporate credit card for personal items.

The Crime and Corruption Commission issued a statement stating a 52-year-old female South Brisbane "suspended senior government employee" is expected to appear in the Brisbane Magistrates Court in January 2018 to face fraud offences.

The alleged frauds relate to misuse of a government department corporate credit card to purchase items for her own use, exceeding $30,000 in value.
