List of Neighbours characters introduced in 2007

Neighbours is an Australian television soap opera that was first broadcast on 18 March 1985. The following is a list of characters that first appeared on the show in 2007, by order of first appearance. All characters were introduced by the show's executive producer Ric Pellizzeri. The 23rd season of Neighbours began airing from 8 January 2007. That month saw both Ringo Brown and Oliver Barnes introduced as brothers of established characters. March saw the year's first baby, Holly Hoyland, born. Con artists Terrence Chesterton and Charlotte Stone arrived the following month, along with Mary Casey. June saw the debuts of Prue Brown, Adam Rhodes, Kirsten Gannon and Mickey Gannon. Oliver's mother and brother, Rebecca and Declan Napier, were introduced in July, as were Bridget Parker, Miranda Parker, Steve Parker and Peggy Newton. Justin Hunter, Richard Aaronow and Riley Parker began appearing from August. September saw Brad Jordan arrive, while October saw the introductions of Marco Silvani, Josh Taylor, Taylah Jordan and Jessica Wallace. Both Angus Henderson and Mia Silvani arrived in November.

Ringo Brown, played by Sam Clark, made his first screen appearance on 24 January 2007. Clark was cast in the role after he won a competition hosted by teen magazine Dolly. Clark was signed to a three-month contract to play the part of Ringo. Clark auditioned four times in total before being cast. His contract was later extended from the initial three months to nine months. The actor described Ringo as being "a good-hearted kid", who does the normal things that a 16-year-old does. Clark explained that Ringo left home to come and live the life his brother, Frazer (Ben Lawson) is living. A writer for the official Neighbours website described Ringo as someone who had "often drawn the short straw in life". They pointed out that he was not an academic, but cheeky and good-humoured. Ringo had previously suffered with anorexia in the past and one of his first major storylines saw him suffer a relapse.

Oliver Barnes, played by David Hoflin, made his first screen appearance on 30 January 2007. Hoflin's casting was announced in October 2006. Hoflin originally auditioned for the role of Will Griggs (later played by Christian Clark), but was forced to turn down the part as he was working on a pilot for another Network Ten production. When that show was not picked up, Hoflin was offered the role of Oliver Barnes, Will's brother. A writer for the soap's official website described Oliver as being "Honest, forthright and fun-loving". They added that unlike Will he has a big heart. Oliver showed his manipulative side when he teamed up with girlfriend Elle Robinson (Pippa Black) to con her father, Paul (Stefan Dennis), out of ownership of his business. Hoflin earned nominations for Sexiest Male and Best Couple, along with Natalie Blair, at the 2007 Inside Soap Awards.

Holly Hoyland made her first screen appearance on 29 March 2007. She was originally played by Chaya Broadmore and then Lucinda Armstrong Hall when the character was recast and reintroduced in 2013. Holly is Karl Kennedy (Alan Fletcher) and Izzy Hoyland's (Natalie Bassingthwaighte) daughter, who was born on a boat on the River Thames. Karl did not know he was Holly's father, until his wife, Susan (Jackie Woodburne), told him. Izzy initially did not want Karl to have a part in Holly's life and Susan agreed with her. Woodburne commented "A child is such a strong connection, and Susan's thinking Karl might decide to try and win Izzy back and make a family with this new child. Susan's quite relieved when Izzy doesn't want Karl involved. She thinks, 'I've told him about the situation and Izzy will look after the child in a happy, loving relationship with her boyfriend, Pete (Daniel Schutzmann), so everyone comes out a winner."

In May 2013, Fletcher revealed that someone from Karl's past would be coming back into his life in the coming months. Fletcher also explained that the new storyline would enable him to make more trips to London, after Karl vows to visit the city at least twice a year. Sophie Dainty from Digital Spy said that this supported the theory that Holly would be returning to the show, following the release of a picture showing a new addition to the portrait at the Kennedy family's house. In June, it was confirmed that Holly would be returning with Lucinda Armstrong Hall in the role. When Holly arrives in Erinsborough, she is now "a precocious eight-year-old", who can do no wrong by Karl. However, Susan's resolve is tested by Holly's behaviour towards her. Claire Crick from All About Soap branded the character "Horrid Holly" and commented "Blimey – we've only seen about five minutes of Holly in Ramsay Street and we hate her already! Could she be any more annoying? We don't think so!" Crick went on to call Holly a "mini-diva", adding that "Horrid Holly better do something to make us like her – and fast!" On 11 March 2014, it was announced that Holly would be returning to Neighbours and she returned on 30 May. Holly made a brief appearance in 2017, and returned alongside Izzy in early 2018. In May 2023, it was announced that the character would return again when Neighbours resumed. The character demonstrates soap opera rapid aging syndrome: six years after her on-screen birth, Hall's casting saw Holly's age increased to eight, and nine years after this her age had advanced again to nineteen.

Izzy Hoyland becomes pregnant after she has a one-night stand with her ex-partner, Karl Kennedy. When she discovers her pregnancy, Izzy leaves Erinsborough. Eight months later in London, Izzy runs into Karl and his wife, Susan. Susan helps Izzy reunite with her boyfriend, Pete, and he urges her to tell Karl the truth about the baby. The following day, Izzy watches as Karl and Susan are remarried on a boat on the Thames and she goes into labour. Karl delivers their daughter and Izzy names her Holly. Deciding not to ruin Karl and Susan's day, Izzy keeps quiet about Holly's paternity. However, Susan overhears Izzy and Pete talking and she tells Karl once they return home. Izzy initially asks Karl to stay out of Holly's life, but he flies back to London to spend time with her. Susan later agrees to become Holly's godmother and Karl tries to visit her as often as he can.

When Izzy goes on a cruise with her new partner, she puts Holly on a plane to send her to stay with Karl and Susan. Holly is happy to see her father again and spend time with him. However, she makes her dislike of Susan clear by glaring at her and calling her old. Holly later admits to Karl that she is missing Izzy. Susan rebukes Holly when she spills nail polish on the couch. Holly believes Susan hates her because of who her mother is, but Karl tells her that is not true and asks her to make an effort with Susan. Holly draws a picture of her mother and crosses her out, causing Karl to realise that she is angry at Izzy. When Holly tries to add a picture of herself to the Kennedy portrait, she falls from the stool she is standing on, hurting her knee. Karl tends to the injury and learns that Holly wants to be part of the family. Holly later tells Karl that she is worried that Susan does not like her, but Karl assures her that is not the case. Susan sits her down and explains to her that despite their rocky start, she does care about her. They both admit to being scared of each other at first and decide to give each other a chance. Holly then admits that she wants to stay with Karl and Susan. When Karl tells Holly that Izzy is letting her stay for longer, Holly believes that she does not want her. Holly tells Karl and Susan that she wants to go back home and Karl flies to London with her.

Holly returns the following year, after Susan organises a surprise visit for Karl. After Holly sings with Karl, he realises she has a good singing voice and he enters her into a junior talent competition. After she witnesses the judges criticising another contestant, Holly becomes nervous and runs off stage. Karl assures her that she does not have to sing in public if she does not want to. Holly recognises a man from a CCTV still as Victor Cleary (Richard Sutherland), a friend of her mother's, who becomes the prime suspect in Kate Ramsay's (Ashleigh Brewer) murder. Holly is delighted when she gets to spend some time with her half sister, Libby (Kym Valentine), and nephew, Ben (Felix Mallard), before she leaves. When Karl comes to London three years later, he brings Holly to visit Toadfish Rebecchi (Ryan Moloney) in the hospital, before taking her to see her friend. Later that year, Karl flies out to London on Christmas Day to be with Holly after Izzy absconds with a new partner.
