Southern Cross Austereo is reportedly surveying its listeners to ask them whether Kyle Sandilands should be sacked, after his recent on-air spray about a journalist sparked an exodus of advertisers and an online furore.

Listeners have been asked if the radio host should be fired and whether they had stopped tuning in to 2DayFM or had boycotted advertisers after Sandilands verbally attacked a News Ltd journalist, The Australian's website reported.

A spokeswoman for Austereo, which owns 2DayFM, confirmed the company had been conducting a survey.

"We're doing a lot to gauge the reaction of our clients and listeners," she said.
