On Monday 27th of November, 2017, Lee gave the following speech in the Senate.

 To Senator Dean Smith: thank you so much for your speech. I found it incredibly moving and it captured the unique circumstances that are about to deliver marriage equality. To senators Janet Rice, Penny Wong, Louise Pratt and Sarah Hanson-Young: your speeches also took us into the intensity of this issue in terms of people's feelings and the long road that it has taken to get us to this point. Thank you so much for your words and actions. I found them extremely moving.
