Nicole Kidman voted the most influential mum in Oz
The study of more than 2000 people was carried out by brand, media and communications researchers Millward Brown.
According to the Daily Telegraph, Kidman had a score of 65 percent and Rebecca Gibney and Olivia Newton John both at 63 percent at the second place.
"This is a list of mothers who could most influence buyer-behaviour," company account director Hannah McHard, was quoted as saying.
"Nicole Kidman tops the list because she is seen as clever and sensible; she has been through a lot and her strength of character is something that many mothers would identify with," she added.
