Murray Olds: Australian correspondent on the Queensland police shooting - Heather du Plessis-Allan Drive

Questions continue to swirl over what prompted a deadly attack on police in Queensland.

Six people are dead- two officers, a neighbour, and three alleged offenders after a check up by four officers on a missing person report turned fatal.

They were looking for a former New South Wales school principal at the property owned by his brother and sister in law, where the shootout took place.

Australian Correspondent Murray Olds says little else is known about the case.
