Two police officers and a neighbour killed in a domestic terror attack that "touched the soul of the nation" have been remembered in tearful tributes in Queensland parliament.
Constables Matthew Arnold and Rachel McCrow were shot dead by Nathaniel, Gareth and Stacey Train after the officers arrived at their Wieambilla property, more than 300km west of Brisbane, on December 12.
Constables Randall Kirk and Keely Brough escaped the attack, which last week investigators said was a domestic terror crime motivated by extremist Christian beliefs.
