One of the character's most notable storylines saw her fall in love with and share a kiss with Karl Kennedy (Alan Fletcher), a married doctor.
[2] Charles commented that it was "very exciting" to be joining the cast of Neighbours and added "At home in England I was a big fan of the show.
Sarah and Karl revealed their feelings for each other at the end of the 1997 season and Craig Platt of The Age called it one of the serial's "most memorable" cliffhangers.
[8] Sarah and Karl's sexual tension became central to the show throughout 1998 and the storyline gave Neighbours a large ratings boost.
[9] Karl and Susan's daughter, Libby (Kym Valentine), was also upset, as she was close friends with Sarah and knew that she had been in love with a married man.
[13] A writer from Inside Soap proclaimed that Sarah had not had much luck with men in the past, but they hoped that Peter would break the pattern and mend her broken heart.
[13] Sarah asked Lou Carpenter (Tom Oliver) to give her away and Amy Greenwood (Jacinta Stapleton) to be her bridesmaid at the wedding.
[15] Of the wedding, Sydney Morning Herald writer Doug Anderson said "Can Sarah Beaumont make it to the altar on time to tie the knot (around her neck preferably), with Dr Peter Hannay?
All the leftover mishaps from the stage play, Secret Bridesmaid's Business, are slathered over the screen as Karl sulks darkly somewhere and Lou carries on like a counter lunch.
An Inside Soap columnist explained "Sarah and Karl give into the feelings they've been stifling for months, and share an illicit passionate kiss.
[15] On 7 January 1999, Matthew Wright from the Daily Mirror reported that Charles was quitting Neighbours to move to London with her new fiancé.
[20] In January 2005, Neil Wilkes from Digital Spy reported that producers were trying to get Charles to return to Neighbours for a cameo appearance in their 20th anniversary episode.
[22] Charles revealed that she was "thrilled" to be asked to return for the anniversary special, but she equally "horrified at the prospect" because she had recently given birth to her daughter and felt overweight.
[25][26] Speaking to Daniel Kilkelly from Digital Spy, Charles said that she received an email from the serial's executive producer after the Inside Soap interview was published and she "made it quite clear" that she was open to a return.
[27] When asked if a return was something she had to take time to think about, Charles told Kilkelly "When the magazine first posed the question I was stunned.
"[27] Charles began filming her return scenes in October and commented that she was open to a longer stint with the show in the future.
[28] Charles told Kilkelly that she found it easy to slip back into the character of Sarah and thought that it was more fun now she is "a grown-up".
[30] The show's series producer Jason Herbison stated, "Sarah Beaumont is a wonderful character that doesn't need an introduction, viewers wait with bated breath for her next move and the latest instalment will surprise everyone.
"[30] Sarah arrives in Erinsborough and successfully applies for a job at Danni Stark's (Eliza Szonert) clothes shop.
Sarah starts receiving phone calls from UK journalists and Joanna Hartman (Emma Harrison) recognises her from some magazines.
After resuscitating Deidre Kaufmann (Lidia Faranda), a patient who went into cardiac arrest, Sarah is reprimanded by the hospital board as she is not qualified enough to perform such procedures.
Sarah attends Catherine's wedding to Malcolm Kennedy (Benjamin McNair) in London and it is revealed that she and Peter have had a daughter called Antigone.
Sarah appears in Annalise Hartman's documentary about Ramsay Street and mentions that she was not fooled when Toadie sent her Bib, a dog almost an exact double of her pet, Bob.
Sarah comes to Ramsay Street to thank Karl for helping her, but as he is out, Ben Kirk (Felix Mallard) lets her wait inside with him.
Sheila Canning (Colette Mann) later invites Sarah to stay at Number 26 with her and her granddaughter Xanthe (Lily Van der Meer).
After Susan accidentally traps Sarah's fingers in her car door, Karl treats her at the hospital and she reveals to him the reason why she is in town.
She then tells Karl that she came to town to ask him and Susan to take care of her son Angus (Jai Waetford) indefinitely and they agree to do so.
[3] Speaking positively of Sarah, a writer from Virgin Media stated "She was the sole reason teenage boys tuned into Neighbours each night between 1996 and 1999.
[33] Simon Kent of The Sun-Herald said Sarah had a "waspish tongue and sharpish put down", while Tony Squires of The Sydney Morning Herald branded her "luscious.
"[34][35] Squires' colleague Ben Pobjie wrote that everyone remembers where they were at the time they watched Karl kiss Sarah behind Susan's back.
