The station, owned by Fairfax Media, which also owns The Age, scored a 15.0 per cent market share overall up from last month's 14.6 per cent. ABC 774 also increased its share, moving from 10.8 per cent to 11.3 per cent.

3AW's star broadcaster Neil Mitchell again won his battle for the mornings slot against his chief adversary at the ABC, Jon Faine, scoring an 18.1 per cent share. Faine, however, increased his audience share, moving from 11.1 to 13.5 per cent.

It was a similar story in the all-important breakfast slot where Ross and John on 3AW, who are currently broadcasting from London, catapulted to a massive 19.1 per cent share, up from 17.1 per cent. They are trailed by Red Symons on 774, who has 15.1 per cent.

Next back is Fox FM's Matt and Jo Show which has a 10.8 per cent share.

On the FM dial, Nova 100 had a strong survey, scaling up to 7.3 per cent from 6.7. Station staff were pleased with Hughesy and Kate's breakfast show, which is now the top-rating breakfast program in the 18-39 demographic.

Sister station Smoothfm 91.5, which was relaunched in May, added 65,000 new listeners in the survey.

At Triple M, and in particular at Eddie McGuire's Hot Breakfast show, ratings were down. McGuire's show had a big fall, sliding from 8.0 per cent to 6.2 per cent. Overall, Triple M was down to 6.2 per cent from 7.5 per cent.

Craig Bruce, head of content at Southern Cross Austereo, the owner of Triple M, said the fall was not surprising.

"It came down a little more than we hoped," he said. "We lost a little consistency from our shows."

Both Gold FM and Mix 101.1, who have new breakfast teams this year, had minor increases in audience share.

Fairfax station Magic earned a 5.2 per cent share and SEN was down to 4.4 from 4.5 per cent.

Elsewhere, national youth broadcaster Triple J increased its share slightly, with breakfast show hosts Tom Ballard and Alex Dyson and Zan Rowe's morning show performing solidly in their demographics. Triple J gained audience share in the 25-39 demographic.
