Terese's turbulent marriage to Paul was rekindled in the serial's finale episode; she returned in a regular capacity for the series' revival in 2023, which focused on the character's wedding to Toadie Rebecchi (Ryan Moloney).

"[2] The character of Brad Willis (formerly Benjamin Mitchell and Scott Michaelson, now Kip Gamblin) was reintroduced to the show, along with his wife Terese and their teenage twins; Josh (Harley Bonner) and Imogen (Ariel Kaplan).

[13] Prior to relocating to Erinsborough, Terese had become the breadwinner and was running the family, as Brad was busy coaching Josh, who was a competitive swimmer.

[16] Elmaloglou hoped that Brad and Terese's youngest daughter, Piper, would be introduced at some point, especially after the characters began talking about her more during storylines.

[18] She explained that Terese had been fine with the fact that Lauren and Brad had dated, but she struggled with the new situation and she worried about her own family and how the news would affect them.

[9] Elmaloglou added that the diagnosis would affect the family and she hoped Donovan and Jones would return to explore the storyline further, as it is a common disease.

[21] Dennis told John Burfitt from TV Soap that Paul wants to make Terese as uncomfortable as possible in order to get rid of her from the hotel.

[26] As Terese worries about her job, her children's problems, and Brad's closeness with Lauren, whose husband Matt died, she turns to alcohol to cope.

However, Sheila Canning (Colette Mann) soon notices some of the stock at The Waterhole has been stolen and sets up CCTV on the storeroom, where Terese is caught helping herself.

"[28] When Paul goes on trial for causing an explosion at Lassiter's, which contributed to the deaths of Doug and Josh, Terese commits perjury in a bid to see him jailed.

Elmaloglou was understanding of Terese's reaction, but due to her experience with her mother, she felt that someone diagnosed with cancer needed love and support from their family, as the treatment could be "very debilitating".

She survives the shooting, but the incident raises the subject of her feelings for Paul, whose relationship with Jane Harris (Annie Jones) ends when she realises he is still in love with Terese.

After Terese stays late at work, Brad accuses Paul of trying to take advantage of her in front of an inspector, costing the hotel its five-star rating.

Ryan is behind a series of hidden cameras found in Lassiter's, so Terese confronts him and eventually gains the USB that the footage is on, using the help of Tim Collins (Ben Anderson).

Terese fires Courtney Grixti (Emma Lane) when she wrongly assumes that she has been giving the male clients of the day spa erotic massages.

When Terese returns from her honeymoon, a hidden camera is found in a Lassiter's room, forcing her to briefly step down as hotel manager.

Tim Collins causes strife for her by posting an article on the West Waratah Star newspaper that features a comment Terese made five years, which countered her decision to halt celebrations.

Terese meets with Indigenous councillor Jacinta Hay (Maurian Spearim) to discuss Aboriginal and Torres Strait Islander representation among Lassiter's staff.

Terese receives the final blow when she discovers that Paul paid Holden Brice (Toby Derrick) to give a fake testimony against Harlow's boyfriend, Brent Colefax (Texas Watterson).

He also allows Terese to organise a fashion show week in full knowledge that Lassiter's partnership with Montana Marcel (Tammin Sursok) will end disastrous due to her secret financial issues.

She begins a relationship with her neighbour Toadie Rebecchi (Ryan Moloney), who has recently been left by his wife Melanie Pearson (Lucinda Cowden).

"[47] Daniel Kilkelly from Digital Spy observed that Terese had received a lot of positive feedback and Elmaloglou was pleased that viewers were loving her character.

[15] A Sunday Mail reporter noticed "The fued [sic] between Terese and Paul shows no sign of abating as we move in to the New Year.

"[48] A writer for The Sun newspaper's TV Magazine noticed that Terese was left "frustrated and helpless" during Imogen's eating disorder storyline.

[49] In February 2014, another writer for the publication stated that everyone wanted Terese to get her job back, explaining "Without her at the helm, Lassiter's is falling apart.

"[50] After Lauren revealed that she and Brad had a daughter, Laura Morgan from All About Soap said she was "pretty sure possessive Terese won't be happy about her hubby spending time with his former flame.

"[51] Morgan later questioned Terese's personality transplant, saying "The ballsy businesswoman has always been no-nonsense and forthright (and we love her for it), but since discovering Paige is Brad's daughter she's turned into a full-on soap bitch.

[34] When Terese turned to Paul for comfort during her cancer treatment, Anna Brain of the Herald Sun quipped: "Bad news has a funny effect on people.

[59] Journalist Adam Beresford described her as a work driven "pocket dynamo" who was "more fun to watch" because of her "hot tempered and impulsive" love life.

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