Time spent tuned in to a radio increased in 2013, as commercial radio grew its weekly cumulative audience by 2.4% last year.
While the home (45%) was still the main place for radio listening in 2013 listening in the car continues to rise, according to Commercial Radio Australia (CRA).
Time spent listening in the car hit 36% in 2013, up from 34% in 2012.
Car radio listening has increased steadily from 2008 when it sat at 28% before increasing to 32% in 2010.
Young Australians proved to be avid radio listeners in 2013 with 85.6% of 10-17 year olds tuning in in 2013, making the group the highest cumulative audience for commercial radio.
More than eighty percent of 40 to 54 year-olds listened to radio last year.
Breakfast is still the most popular time of day to tune in; More than seven million people listened to weekday breakfast radio in 2013 with almost 6.5 million listening during drive time in the five metro markets.
The figures are based on an average from the eight radio surveys of the five metro markets in 2013. The averages are compared to the 2012 results with the above figures the final ones Nielsen will provide CRA.
GfK took over the radio audience measurement from Nielsen on January 1, 2014.
