Barber has appeared in various television shows but is perhaps best known for her role of paramedic Bree Matthews in the TV show All Saints and for her roles in Office Correctness and How Not to Behave. Barber was a sketch writer/performer on The Matty Johns Show. She was also part of a film called Burke & Wills which went on to become a finalist at the 2006 Tribeca film festival. She has been a panelist on Have You Been Paying Attention? and also was a co-host on Studio 10.
Comedy
Although Barber started out in acting she later fell into comedy. Barber states: "I've always been told I've been funny but I always thought funny was stupid. I thought if you were a bit of an idiot then that was funny. But I've since learnt, no, not the case, and being funny is the best and I love it… My late friend Mark Priestley, who worked on All Saints with me, was like, "This is your niche," and he helped me focus on it. In 2015 she was a MICF Raw Comedy state finalist and sold out shows for both the Sydney Comedy and Fringe Festivals.
Writing
Barber released her first book: Celeste Barber - Challenge Accepted in September 2018. It's described by Barber as "253 Steps to becoming an anti-it girl". Barber's second book was a children's book titled: Celeste the giraffe that loves to laugh and it was published in October 2019.
Instagram
In Early January, 2015, the earliest instances of Celeste recreating photos of celebrities and famous women began to emerge on her Instagram. Celeste and her sister would send each other text messagesback and forth of how women are supposed to do everyday activities and they began to poke fun at the depiction. In September 2018, Celeste was featured in comedy videos released by Tom Ford. The three videos, posted to Barber and Ford's respective Instagram accounts, show Ford teaching Barber how to walk in his shows, while she attempts to sneak some of the clothes home in her bag. The video played at the after party of Ford's show, which opened New York Fashion Week. The videos come after the pair collaborated on a previous comedy video featuring Ford and Barber vigorously making out in an airport terminal.
Fundraising
During the devastating 2019–20 Australian bushfire season Barber launched a fundraising appeal with a target of raising A$15,000 for the New South Wales Rural Fire Service's RFS Brigades Donation Fund. The fundraiser went on to raise over A$50 million, making it the largest ever held on Facebook. After the money was raised, Barber learned that the RFS Fund was by law restricted to training, resources and equipment, and could not be redirected to communities or volunteers. The RFS and Barber's legal team have been working with the courts and legislature to find a way to disburse the funds more widely.
Other work
Barber started her own podcast in April 2019 titled Celeste and her best, she often featured a host of her famous friends including Lisa Rinna, Jameela Jamil, Busy Philipps, Cindy Crawford and many more.
