Brad Willis is a fictional character from the Australian soap opera Neighbours. He made his first screen appearance during the episode broadcast on 31 October 1989. The character was initially played by Benjamin Mitchell, before Scott Michaelson took over the role two years later. Brad was re-introduced alongside his sister, Gaby, during a period of roller coaster ratings for the show. Michaelson revealed that as soon as he learnt he had won the role of Brad, he went surfing five days in a row, as he knew he was going to be busy over the upcoming months. Michaelson signed a new twelve-month contract with Neighbours in October 1992 and a year later, he announced he would be leaving the soap. Michaelson filmed his final scenes in November and departed on 15 December 1993.

Lucy Robinson is a fictional character from the Australian soap opera Neighbours, played by Melissa Bell. The character has previously been portrayed by Kylie Flinker and Sasha Close. She was created by producer Reg Watson as one of the serial's original characters. Lucy was a prominent figure during the early 1990s of Neighbours, with Bell playing her on and off for five years. Portrayed originally as being clever, a recast was implemented to fit the character's transformation and she became the stereotype of a ditzy blonde female. She has been involved in storylines including battling a brain tumour, coping with blindness, incest, modelling and addictions to drugs, alcohol and spending. She has also been positively and negatively received by critics for her "busty blonde" image while played by Bell. After making a brief return on 6 May 2013, Lucy made subsequent return visits until 2016. She was reintroduced as part of the serial's 35th anniversary in 2020, before returning briefly in late 2021 as part of the reintroduction of her half-brother, Glen Donnelly, and twice in 2022, appearing in the show's finale episode. Bell returned on 18 September 2023 following the show's renewal, but departed again on 21 September 2023. Bell returned again on 13 February 2024 for three episode centered around David Tanaka's death and left again on 15 February 2024.
