Kerr's model trademark is her dimples. Celebrity photographer Russell James said of Kerr, "The US has fallen in love with her. We love her because she has the most incredible girl-next-door look and she's also insanely beautiful. It means women are not intimidated by her looks and guys think they might be able to talk to her. It's a fantastic combination ... people want to be around her; she's fun on a shoot … and she's not stupid, which can be a very annoying trait among some models." Model agent Ursula Hufnagl described Kerr as "the perfect endorsement", citing her ability to "truly sell a product."
She has been ranked in FHM's '100 Sexiest Women' poll at #56 in 2009, #36 in 2010, and #44 in 2011.
Kerr's charitable work includes Wildlife Warriors Worldwide and Children International.[17] In June 2009, Kerr posed naked, chained to a tree, for an issue of Rolling Stone Australia magazine, in order to raise awareness for the endangered koalas.
In early February 2010, Kerr inadvertently became the subject of global headlines when David Kiely, a banker at Macquarie Bank in Sydney, was caught viewing "racy" photos of the model on his computer while in the background of a colleague's live television interview with Channel 7. Within days, a clip of the interview uploaded onto YouTube received over 1.3 million hits. When Kiely was suspended and an internet campaign launched on his behalf, Kerr herself gave him her backing: "I am told there is a petition to save his job, and of course I would sign it." The episode prompted a 100% increase in the number of Google searches for Kerr's name. A few days after the incident, Macquarie Bank announced that Kiely would keep his job.
