Six new cases of coronavirus have Queensland on high alert just days before the NRL Grand Final in Brisbane after a truckie drove around the state while infected.

The NRL have drawn up contingency plans as an emergency back up if Brisbane is hit by a sudden outbreak that can't be contained in time.
QLD Premier Annastacia Palaszczuk insisted though: 'There is no need to panic.'
Two of the new cases were overseas acquired, and one is an international traveller who tested positive after they came out of hotel quarantine.
