The quartet of Christians plan to hide in the 30,000 square kilometres of the Shoalwater Bay military training area near Rockhampton to disrupt joint exercises by the Australian and US armies, navies and air forces, involving about 24,000 troops.
In the early hours of this morning, the group, calling themselves the Bonhoeffer Four, stole onto the base, knowing that the exercise cannot go ahead while they are loose. They are aligned with a larger Christian group, the Martin Luther King Junior House Church, which is loosely connected with the wider Peace Convergence protest.
The group's namesake, Dietrich Bonhoeffer, was a great German theologian who was hanged in 1945 for supporting a plot to assassinate Hitler. Prime Minister Kevin Rudd identified Bonhoeffer as his inspiration in a major essay in The Monthly in 2006.
"Our faith is calling us to this," Mr Moyle said. "We have committed our lives to taking seriously Jesus' call not just to be peace lovers but peace makers, and to love our enemies."
He said he didn't know how many groups would try to hide. They had to signal that they were there, with balloons and beacons, which made it harder, but their hiding spot is the size of Belgium.
"The military are doing invasion training. They have built a model city inside the base with a mosque in the middle, which the Australians are defending against the Americans," he said.
