A neighbour who was with Sean Ferris minutes before he stabbed two police officers and was then shot dead says the incident should never has escalated to this — as homemade weapons and a Samurai sword are removed from the property.
Neighbour and friend David Wallace, told ABC News Mr Ferris was known to have mental health issues and was a collector of weapons.
"It just shouldn't have escalated to this at all," he said.
He said Mr Ferris had homemade weaponry at his house, which he had in the first room of his property.
Mr Wallace said entering Mr Ferris's property "in those circumstances was a dangerous one".
