A solitary male was hopping along casually when a second male came bursting out of the shrubbery making a loud "woofing" noise. They fought and it was a fierce encounter with much grunting. After a while they had a rest. Then they had another go until one decided he had had enough. He left with the victor following and adding some more loud woofing for emphasis...... near the Molonglo River and east of Denman Prospect.
