A camouflage-clad Nathaniel Train, driving a black 4WD carrying loaded guns and military knives, broke through the NSW border gate into Queensland in December last year.
The COVID-19 border breach — along with other evidence that the former school principal potentially broke laws relating to the possession and disposal of weapons during the same incident — was reported to Queensland police less than a year before Train was involved in a deadly shooting that resulted in the deaths of two young police constables.
