After eighteen months of playing Kyle on a part-time basis, Milligan was given a full-time contract deal and he and his character were promoted to the regular cast.

Following his promotion to the regular cast, the show's writers gave Kyle some character traits similar to Henry Ramsay (Craig McLachlan).

Kyle engaged in a brief relationship with Natasha Williams (Valentina Novakovic) and developed a crush on Kate Ramsay (Ashleigh Brewer).

[5] After eighteen months of playing Kyle on a part-time basis, Milligan was promoted to the regular cast and given a full-time contract deal.

"[12] When Kyle first joined Neighbours, he was an immature "bad boy", who often hung around with school bullies, Justin Hunter (Chris Toohey) and Shane Gregory (Ryan Bate).

[14] Following a traumatic rafting accident on a school trip and his struggle to find employment, Kyle decided to change as he did not want to be the same person anymore.

[16] Of this, executive producer Susan Bower explained "He was at school with the gang and he's been back and forwards quite a lot, and we certainly feel that he has a future for the show - in much the same way as Henry Ramsay was sort of the handyman around the place.

[13][14] During an interview with Digital Spy in June 2011, Milligan revealed Kyle would eventually start his own handyman business, which would bring him into contact with all of the Ramsay Street residents.

[7] In August 2011, Bower told Daniel Kilkelly of Digital Spy, that Kyle was a guy with double standards, who "goes out and shags indiscriminately, but the girl he wants to marry has to be an angel.

[7] Following an injury in early August, Milligan was forced to take a break from filming and Luke Pegler was brought in and cast as Dane Canning, Kyle's cousin.

"[19] In January 2012, new executive producer Richard Jasek revealed that Kyle's grandmother was being cast and it was later announced that Colette Mann had received the role of Sheila Canning.

[20][21] Sheila comes to Erinsborough to make a surprise visit to Kyle, but after she meets his neighbours and begins to like the life he has, she decides to stay.

Of Kyle's relationship with his grandmother, Milligan told a What's on TV writer "The Cannings are a very close, working-class family and his gran rules the roost.

[31] When Kyle supported Georgia Brooks (Saskia Hampele) through a tough time at work, she began to question her relationship and future with Scotty Boland (Rhys Uhlich).

[33] When Georgia made a quick exit from the fundraiser, Kyle got confused and thought she had developed a crush on his house mate Rhys Lawson (Ben Barber).

"[34] When Kyle came to Georgia's place to fix the pool, she offered to put some sunscreen on his back and TV Week's Thomas Mitchell declared that "the electricity is off the grid!".

[36] When Kyle decides to hold a sale at the car yard to bring in extra revenue, it attracts the attention of Constable Wes Holland (Daniel Hamill).

[41] In March 2016, Daniel Kilkelly (Digital Spy) confirmed Milligan had left the show and added that Kyle would be on-screen for "a few more weeks.

After surviving the disaster, Kyle decides to "put his own happiness first" and leaves Ramsay Street with Georgia, who has secured a nursing job in Europe.

"[51] Kyle reveals that he has returned as Paul has offered him Amy's former job of overseeing the Robinson Pines housing development, which means they will have to work together during a handover period.

[51] On 14 March 2022, Kilkelly (Digital Spy) confirmed that Milligan would be departing Neighbours, alongside Zima Anderson, who plays Kyle's wife, Roxy Willis, in episodes broadcast at UK pace in April.

Principal Andrew Simpson (Peter Flanigan) bans pranks on muck-up day and suspends the boys when they run through the school wearing balaclavas and spraying silly string.

Kyle learns Georgia is pregnant and manages to convince her to stay in Erinsborough by proving that he is able to take care of her and the baby financially.

He explains that Gary owes Amy a large amount of money, and that he moved stolen goods and accidentally knocked out Dipi Rebecchi (Sharon Johal) in an attempt to pay her back.

Their relationship is strained when a tape of them having sex in a Lassiter's hotel room is leaked to the media by Scarlett Brady (Christie Whelan Browne).

Kyle attends Elly Conway's (Jodi Anasta) 35th birthday party on Pierce Greyson's (Tim Robards) island, after falling out with Gary due to his engagement to Prue Wallace (Denise van Outen).

"[60] In October 2011, another reporter from the Daily Record praised Kyle's promotion to regular cast member, saying "whoever decided to bring him in on a permanent basis deserves a big pat on the back.

[61] Cameron Adams of the Herald Sun called Jade and Kyle's relationship "bumpy" and he praised Milligan for not letting his torn Achilles stop his character from hobbling around on crutches.

[64] In 2021, Kyle was placed fourth in a poll ran via soap fansite "Back To The Bay", which asked readers to determine the top ten most popular Neighbours characters.

[65] In a feature profiling the "top 12 iconic Neighbours characters", critic Sheena McGinley of the Irish Independent placed Kyle as her sixth choice.
