University of Sydney staff went on strike for the fifth time in a year on 9 March. Tutors, lecturers and professional staff refused to teach classes, answer emails or attend to their regular duties for 24 hours. Eastern Avenue, normally a densely packed thoroughfare, was deserted. Fisher Library, where most students go to study on campus, was empty. The only activity occurred at the entrances to campus, where the National Tertiary Education Union had formed picket lines of staff, supported by students, to enforce the strike.
