Aaron Brennan is a fictional character from the Australian soap opera Neighbours, played by Matt Wilson. The actor received the role after a long casting process, during which Wilson sent the producers a recording of himself performing a scene, before attending an audition. Wilson relocated from Sydney to Melbourne for filming. The character was initially intended to be a guest part, but due to Wilson's "endearing quality", he was promoted to the full-time cast. He made his first screen appearance during the episode broadcast on 16 June 2015. Aaron was the third Brennan sibling to be introduced, following his brothers Mark (Scott McGregor) and Tyler Brennan (Travis Burns) in 2010 and 2015 respectively. Aaron is portrayed as a confident, happy, occasionally naive, optimist. He was initially shown to be closer to Tyler than Mark, but the brothers were bonded when their estranged father was introduced. The character had a unique entrance to the show as an exotic dancer performing at The Waterhole. Wilson took dance lessons ahead of his first scenes. Aaron has embarked on various careers throughout his duration, including bodyguard and social media manager. Aaron is openly gay, and he has formed relationships with established regular Nate Kinski (Meyne Wyatt), despite initially having nothing in common, and later Tom Quill (Kane Felsinger) and David Tanaka (Takaya Honda). The character has received a positive response from television critics and viewers. He was named Best New Male Character of 2015 by a columnist for Soap World.
