Students were asked to advise Robinson on whether this constituted harassment under the Harassment Act 1997.
Adjunct lecturer Nick Chapman, who confessed to watching "a couple of episodes to know what was going on" said the use of the reality show was about increasing students' interest to get a teaching point across.
He said the slide was met with groans and laughter.
Even rejected contestant Kristie Leonard posted online: "Bachelor in Law has a whole new meaning these days - check out what they were doing in a law lecture at Victoria University today."
Although Robinson was the first contestant to share a passionate embrace with Green, it passed without recrimination from the others.
Chapman had been taking a bit of stick from colleagues.
And was it harassment?
Chapman said: "Leaving offensive material where somebody can find it may constitute an act of harassment but there's big emphasis on the word 'may'.
"In this case, it's probably not serious enough. Another point to note is harassment needs a pattern of behaviour. One act alone isn't sufficient."
Chenery was eliminated from the show on Wednesday, leaving Robinson, Alysha Brown, Matilda Rice and Poppy Salter in contention to be chosen by Green as his leading lady.
