Isabelle "Izzy" Hoyland is a fictional character from the Australian soap opera Neighbours, played by Natalie Bassingthwaighte.

"[4] Robert Fidgeon of the Herald Sun wrote that Izzy would get "male pulses racing" and called her "a compulsive flirt with a bubbly nature".

[3] Of her fictional backstory, Fidgeon wrote that Izzy uses her bubbly personality to hide her abandonment issues caused by her mother leaving in the late 1970s to "find God".

[3] Bassingthwaite told him that Izzy was a great character to play, saying she was "outwardly a charmer, inside a schemer, unscrupulous and a home-wrecker.

[5] Stuart Parker (Blair McDonough) and Lou Carpenter (Tom Oliver) both approach her about their various problems, and Izzy tells them what they want to hear, making "an instant impression.

I've had an amazing time and, while it's great to have a regular income and live a normal life, if you stay in one spot too long you get rusty".

[11][12] Bassingthwaighte was invited to return to Neighbours for the show's 30th anniversary celebrations in 2015, but she declined the offer because she felt "the timing wasn't right".

[13] However, Bassingthwaighte agreed to take part in the documentary special Neighbours 30th: The Stars Reunite, which aired in Australia and the UK in March 2015.

[14][15] On 28 October 2017, Jonathon Moran of The Daily Telegraph reported that Bassingthwaighte had reprised her role and had returned to filming that same month.

[18] On 7 May 2022, Dan Seddon of Digital Spy announced that Bassingthwaighte was one of 23 former cast members returning for the show's final episodes, following its cancellation earlier that year.

[19] Susan (Jackie Woodburne) and Karl's (Alan Fletcher) son, Malcolm (Benjamin McNair), returns to Erinsborough to announce that he and Izzy are dating and have fallen in love.

Izzy has an affair with Ned Parker (Daniel O'Connor), which is initiated in an attempt to get him out of Erinsborough, which both Robert Robinson (Adam Hunter) and Lou Carpenter (Tom Oliver) find out about.

After she became suspicious of Robert's behaviour, Izzy tries to convince Paul and Elle that he is responsible for the 'accidents' she was said to have caused, such as leaving the gas on while babysitting her nephew Charlie.

Izzy moves to London and begins an affair with Pete Gartside (Daniel Schutzmann), a married professional football player.

Izzy flirts with Mark Brennan (Scott McGregor) and invites him up to her hotel room, where they are interrupted by Holly and Karl.

Izzy convinces Clive Gibbons (Geoff Paine) to show her the lab where the research projects are being carried out, and she later steals Karl's sperm sample and impregnates herself.

Susan invites Izzy to her birthday party at The Waterhole, where Clive reveals that Karl's sperm sample is missing.

Clint's daughter, Rita Newland (Lisa Kay) challenges her father's will and has his assets frozen, leaving Izzy without any money.

The following year, it is revealed that Holly had returned to Erinsborough on the day of the wedding and witnessed Izzy kissing Shane in his car.

[26] Izzy stealing Karl's sperm during her 2018 return was nominated for "Most Bizarre Soap Storyline" at the 2018 Digital Spy Reader Awards; it came in seventh place with 7.6% of the total votes.

"[5] A critic for The Advertiser noted that Izzy had taken over the "soap bitch" role from Sarah Beaumont, played by Nicola Charles, and they called her a "marriage-wrecking, self-obsessed siren".

[29] Deller said "The best character in Ramsay Street for ages, if not of all time, Izzy was the best kind of soap bitch (see also Janine Butcher and Clare Devine), one whose motives you could understand, and often sympathise with.

Being a member of the largely dreadful Hoyland clan didn't bode well for her, but Izzy soon won a place in everyone's hearts (and several male characters' beds).

She was even bezzie mates with Harold, and she bowed out by giving birth on the Thames in the ludicrous Neighbours goes to London episodes".

[33] Bree Hoskin writing for LGBT website Gaydar, included Izzy on their list of "Top Ten Soap Bitches".

Hoskin noted that Izzy had met her match in Paul, and it subsequently caused "a good vs. evil cul-de-sac showdown the likes of which Ramsay street had never seen before".

Bassingthwaighte revealed that people were shocked to see her friends with Woodburne in real life, because her portrayal of bitchiness was so convincing they assumed they had to be enemies off-screen.

[35] Journalist Adam Beresford accused Neighbours of shying away from featuring "superbitch" characters until "they fully embraced the mayhem" of "blonde troublemaker" Izzy.

[35] Sam Strutt of The Guardian compiled a feature counting down the top ten most memorable moments from Neighbours.

"[37] In 2015, a Herald Sun reporter included Izzy and Karl's first kiss in their "Neighbours' 30 most memorable moments" feature.
