It's radio ratings time again, with the third GfK radio ratings survey of the year revealing a stable leaderboard in major metro markets.

It's the first book since Kylie & Jackie O made their long-awaited entry into Melbourne radio, though with the show only live for final three weeks of the survey period (February 24 to March 30 and April 14 to May 18), ARN's star duo couldn't do much to make ground on market's breakfast leadership board.

Holding on comfortably to the top spot in Melbourne breakfast was 3AW's Ross Stevenson and Russel Howcraft with 19.8 per cent share (up 1.7 points on the last book). GOLD104.3's Christian O'Connell clambered back into the lead in FM on a 10.4 point share, nudging FOX FM's Fifi, Fev & Nick, who undid the gains made last survey, dropping 1.2 points for a 10 per cent share of the breakfast audience.

In their debut on the Melbourne book, Kyle & Jackie O pulled a 5.9 per cent share, dropping 0.5 points on the last book. The next survey period will give a more accurate idea of how the duo is resonating with Melbourne audiences.

Hit Network's Carrie & Tommy on The Fox took back the top spot in Melbourne drive, claiming a 10.6 point share versus GOLD and Dave 'Higgo' Higgin's 10.5 points.

3AW was the overall winner in the Melbourne market, on a 14.4 point share over people over 10 - clearing runners up at GOLD by 3.6 points.

"“ARN’s strength as a network and our dominance in these key markets is a testament to our teams' dedication and the strong connection we have with our listeners. Congratulations to Christian O’Connell on his great results in Melbourne, along with Kyle & Jackie O who continue to dominate in Sydney," said ARN Chief Content Officer, Duncan Campbell.

In Sydney Ben Fordham and Kyle & Jackie O have swapped places again, with the latter falling into second place after dropping 1.5 points in the breakfast time slot. Fordham and 2GB claimed a comfortable win in breakfast with a 1.7 point gain to 16.6 points, versus KIIS FM's 14.7 points.

In Sydney drive KIIS FM's Will and Woody have maintained their lead on smoothfm's Byron Webb, with the gap between the two shows widening to 0.3 points.

Overall, 2GB came out on top in the Sydney market with a 13.3 point share of listeners, ahead of KIIS FM on 10.3 points and smoothfm on 10.7 points.

“These are incredible results for 2GB and solidify our position on top of the Sydney radio dais! This survey period covers the best part of three months of high-impact news, sport and entertainment, and Sydneysiders have overwhelmingly chosen to share the highs and lows with 2GB and their favourite broadcasters. Ben Fordham is the clear Number 1 in Breakfast, Ray Hadley has extended his incredible dominance in Mornings, and the Continuous Call Team is our city's premier Rugby League and entertainment coverage," said 2GB Content Manager, Luke Davis.

In Brisbane, Hit Network's B105 remained the top station overall, with 12.4 points, ahead of its stablemate Triple M on 11.4 points.

"In another day of big number ones, SCA continues to dominate other key metro markets where Triple M has returned to the top spot in Adelaide, powered by an extraordinary 13-in-a-row leading FM Breakfast result from Roo, Ditts & Loz," said Southern Cross Austereo's Chief Content Officer, Dave Cameron. "In Brisbane, SCA has taken out the no. 1 and 2 positions overall with B105 and Triple M, and in Breakfast with B105 and Triple M no. 1 and 2 respectively. B105's Stav, Abby & Matt have cemented their place as the city's favourite Breakfast show."

Cameron said the network had claimed another win as the top network for the 25-54 audience nationally, which he said proved "that the critical monetisable audiences for advertisers are engaged on SCA's brand-safe stations and show environments".

Australian commercial radio reached 12.41 million listeners this survey, and according to Commercial Radio & Audio (CRA) has seen year-on-year (YOY) growth in morning show listenership

"The rise in morning listenership, partnered with increased engagement during commutes, shows how seamlessly radio integrates into our lives," said CRA chief commercial officer, Jo Dick. "Radio's not just a source of information and entertainment, it's a central part of our routines." A

"It's great to see our audience consistently growing. With 18 to 24-year-olds listening for almost 11 hours weekly, radio's appeal clearly spans generations," Dick said. "Survey 3 highlights the strength of commercial radio as it continues to evolve in tandem with shifting listener habits and their growing preference for flexibility."
