In the early 1990s, Phillips worked at TVQ-10 Brisbane as a reporter and presenter and she made her national debut as regular presenter on Ten Eyewitness News weekend late edition (from Network Ten's Brisbane studios) in 1993. A year later, Phillips moved to Sydney to join Ron Wilson on TEN-10's Ten News First at Five, succeeding Sandra Sully and she was lead female presenter for the bulletin for two years and was later succeeded by Jessica Rowe.
In 1997, following a stint as presenter with Sky News Australia, Phillips moved to London where she worked as a news presenter at BBC World News while at the same time running a London café. She later moved to CNN International, also in London, working mainly as co-anchor on CNN Today before returning to Australia as weekend presenter of ABC News in New South Wales.
On 30 November 2007, Phillips suffered an on-air coughing fit while presenting ABC News NSW, forcing the ABC to switch to a simulcast of the Victoria state bulletin from its Melbourne station until her coughing fit subsided. In her 2010 book, A Pressure Cooker Saved My Life, she describes the episode as a result of a stress-induced laryngeal spasm.
On 19 November 2013 The Australian published the ABC's top salaries: host Juanita Phillips salary is $316,000.
In 2002, Phillips married Mario Milostic, an Australian graphic designer, after a six-week courtship. Their first child was born in 2003 and their daughter in 2006. In 2009, Phillips took carer's leave from the ABC to care for their children while her husband Mario was interstate for rehabilitation from bowel cancer. They separated in 2010.
In 2012, Phillips began a relationship with Federal Government Minister for Climate Change, Greg Combet. In 2013, the relationship attracted some controversy for a first-class overseas trip paid from government funds. In May 2013, Phillips was removed from one evening's ABC News bulletin due to a conflict of interest that arose after Combet faced an ICAC inquiry into government corruption.
In June 2018, during public debate on the Ramsay Foundation bequest to establish a Bachelor's Degree in Western Civilisation, Phillips tweeted: "Perhaps any study of Western Civilisation could examine how and why violence against women is such an integral and accepted part of it #EurydiceDixon".
