Police are hunting a gunman after officers were shot at in the town Tara, west of Brisbane.
No one was reported injured.
Officers have cordoned off an area in Tara, declaring it an exclusion zone with residents told to say indoors.
The shots were fired at 3.30pm and the exclusion zone declared at 5.30pm.
The zones includes Surat Development Rd, Day St, Benn St, Fry St and Milne St.
Several residents have been evacuated.
Tara was the home base for officers Rachel McCrow and Matthew Arnold who were gunned down at nearby Wieambilla property in December.
A resulting shoot-out led to the deaths of four people including Gareth Train, Stacey Train and former Walgett school principal Nathaniel Train who had ambushed the two officers.
The trio were later revealed to be doomsday preppers who believed in a mixture of apocalyptic scenarios where the government was out to get them.
Neighbour Alan Dare, who had come to assist with an unrelated fire on the property, was also killed in the exchanges between the Trains and tactical police.
