UPDATE: JIM DOWLING was convicted on one count of trespassing on Commonwealth land in Rockhampton Magistrates Court today.
The anti-war protester was fined $500 and ordered to pay $1000 in costs to the complainant.
Dowling said he would not be paying any legal costs or fines "on principal".
EARLIER: A PROTESTER set to appear in court today is blaming Australia's military activity in Iraq and Afghanistan for the recent ISIS attacks across the globe.
"Peace Pilgrim", Jim Dowling, goes to trial today for being part of a group of 16 people who occupied Shoalwater Bay military base in July this year.
Dowling declared his intention to do his best to put war on trial.
"War making is the real crime here," he said. "The horror of suicide bombing and terrorist shootings in the west would not be happening today if it were not for our own terrorist activities in waging war in Iraq and Afghanistan," he said.
"We must face up to our own war crimes and cease fighting the terrorist wars of the US Empire"
Dowling was arrested with two other Peace Pilgrims in July on the Samuel Hill airstrip holding a banner with a Bible verse on it.
The Peace Pilgrims are made up of groups of two and three and they walked onto the base to resist the biennial Talisman Sabre US and Australian war games.
Others arrested during the war games, including three "Quaker Grannies", pleaded guilty at the time, and were mostly fined $500 and had their possessions confiscated. Some are presently appealing that confiscation.
