In the ensuing two years, he was repeatedly accused in the university paper of being a right-wing thug and bully who used sexist and racist tactics to intimidate his opponents.
Lawyer David Patch, who is a Labor candidate in the federal seat of Wentworth, recalls an AUS conference in the mid-1970s, which had initiated a special "women's room" for females to discuss political issues.
"Tony used to stand outside the women's room with his right-wing mates and loudly tell sexist and homophobic jokes," he said.
Another ex-student, Peter Murphy, who described Mr Abbott as a "warrior on the Right" believes he was the one most responsible for creating the atmosphere of terror that reigned on campus in 1977.
In August 1977 students on every NSW campus were preparing to vote in a referendum on the future of the AUS. That's when Ms Wilson's and Mr Abbott's paths crossed. Both were addressing a rally of students, held in the Ku-ring-gai campus dining room.
The incident that prompted Ms Wilson's accusation occurred while she spoke.
When it came to court the following January, Mr Abbott was flanked by his parents, a legal team including a QC, and seven witnesses.
Advocates for Ms Wilson are to this day flabbergasted at the firepower Mr Abbott wheeled in, which left their under-represented side wilting.
The incident didn't seem to break Mr Abbott's stride, although his second tilt at election to the Student Representative Council (SRC) - which was happening at the same heady time - ended in tears.
