Sarah, who is in her internship at the Royal Adelaide Hospital, describes herself as "the most colourful" doctor there.
"If you're confident and competent at your job, it shouldn't really matter what you look like," she said.
"I'm just trying to advocate for being your own person and still being able to work in the medical profession."
Sarah had her first tattoo at age 16 and now owns a tattoo parlour with her husband Matt, a full-time tattoo artist called The Grim Raptor.
She's a horror movie fan too, admitting she's always liked the "dark side" of things — but insists she would never have anything "offensive" inked on her body.
"I don't have anything offensive on me anywhere, I think everything is done really well, and I think there's a real difference between getting a tattoo that's of poor quality and getting a tattoo if you're an art collector like myself," she said.
Her unusual status as the "world's most tattooed doctor" has earned Sarah a cult following, with more than 60,000 people keeping up-to-date with her skin collection on Instagram.
In an interview with The Daily Mail Australia last year, Sarah explained she'd been turned away from restaurants and refused service in shops because of her tattoos, which she finds "frustrating".
"When I'm at work, I don't get treated differently for being colourful. Both my patients & senior clinicians treat me fairly nor judge me on my appearance the majority of the time," she wrote in a lengthy Instagram post in April.
She went on to encourage her followers to be "unapologetically themselves", particularly in more conservative sectors so that the "shock factor disappears" and tattoos can become the "norm".
"I only hope that each day education surrounding body art continues to feed through the generations like a ripple affect & those that judge us as 'bad people' based on our appearance fade into the background," she said.
