Willis Family - Doug Willis

Douglas "Doug" Willis, played by Terence Donovan made his first on-screen appearance on 1 August 1990. Donovan departed in 1994, but returned briefly for the show's 20th anniversary in July 2005.

In 2005, Donovan reprised his role of Doug to join many ex-cast members who returned for Neighbours' 20th anniversary. Doug is described as being a "bit of a Regular Joe who didn't like rocking the boat or standing out from the crowd." He is also "a man's man" who is not afraid of using his fists and takes great pleasure from making home-brewed beer with Lou Carpenter (Tom Oliver).

Doug began working as a builder to support his mother and sister, Faye (Lorraine Bayly) after his ex-marine father, Bert (Bud Tingwell) returned to the seas. While accepting a dare on a Buck's night to hail a cab naked, Doug met Pam Beresford (Sue Jones) and they both fell in love. Doug and Pam married in 1967 and had three children.

Doug and Pam purchase Number 28 Ramsay Street. They have dinner with Beverly (Shaunna O'Grady) and Jim Robinson (Alan Dale) and Doug winds Jim up by flirting with Beverly. When Cody's grades suffer due to her dating Todd Landers (Kristian Schmid), Doug and Pam ban her from seeing him. Doug goes into business with Paul Robinson (Stefan Dennis) and they try to develop a retirement village project in the bush. Local councillor Felicity Brent (Rhona McLeod) tries to oppose it, but fails. Doug and Paul fall into debt over the development costs. The Willises take a further financial hit due to Cody's student exchange fees and them bailing Brad (Scott Michaelson) out of jail. Gaby (Rachel Blakely) returns and bails the family out. Brenda Riley (Genevieve Lemon) takes a shine to Doug and constantly flirts with him. Pam accuses Doug of having an affair, but he assures her that he is not.

Faye arrives to stay with the family and Doug is willing to put up with his sister, as she is lonely. However, when Faye tries to get Doug back together with his childhood sweetheart, Alexandra Lomax (Chantal Contouri), he asks her to leave. Faye then moves to Number 32. Jill Weir (Lynn Semler) takes an interest in Doug and leans on him and Pam for support during a custody battle with her mother-in-law over her son, Ross (Che Broadbent). Jill later starts to pursue Doug and he is resistant at first, but gives in after assuming Pam is having an affair with Jim. Doug and Jill have a one night stand, but Doug regrets it and confesses to Pam. She throws him out and files for divorce. However, when Doug and Brad are lost at sea, Pam realises how much she really loves him and they reconcile, when he returns. Doug's father, Bert, arrives and Doug is frosty with him as he walked on the family when he was young. Doug becomes angry when he discovers that Gaby has been in contact with Bert for many years. After learning that Bert is dying, Doug makes peace with his father.

Doug faces more money problems when his company is audited and goes into debt. He sells the business to Constructacon and he is kept on as a foreman. However, he is fired due to poor conditions on the site. Doug sinks into depression and several neighbours try to help him, but he rejects their offers. Doug soon lands a job as a sales representative. Doug and Lou Carpenter begin making their own home-brewed beer and they hide it in the shed of a property Doug is renovating. Doug boss, Andrew "Macca" MacKenzie (John Morris), is not happy, but later joins Doug and Lou in their venture. Gaby gives birth to Zac (Jay Callahan), delighting her parents. Gaby leaves for Darwin and Doug and Pam sell up and join her. Cody dies the following year and Pam brings her body to Darwin to be buried. Years later, Doug receives an invitation from Annalise Hartman (Kimberley Davies) to attend a screening of her documentary about Ramsay Street and he returns to Erinsborough with Philip Martin (Ian Rawlings). Doug and Philip sneak into Number 22 and paint a fake beard on a sleeping Lou. Doug and Philip catch up with old friends and enjoy a barbecue and watch the documentary. Lou then joins Doug and Philip on a camping trip up north.

The BBC said Doug's most notable moment was "Having an affair with Jill Weir."
