The top five stations are now separated by under 2 percentage points – a significant tightening compared to the first survey of the year.

In the closely watched breakfast shift, ABC Radio Adelaide’s Ali Clarke has maintained a clear lead, despite losing ground to her closest competitors, FIVEaa’s David Penberthy and Will Goodings.

David Bevan in the morning shift edged closer to leading talk program, FIVEaa’s Leon Byner, but that was the end of the good news for the ABC. The afternoon and drive shifts lost significant listener share and the evenings result revealed a seismic change – the ABC’s Peter Goers lost 3.8 percentage points (so large it seems anomalous), to relinquish first place to FIVEaa’s evenings line-up of Jon Blake followed by Jeremy Cordeaux.

Overall, long-time leader Mix 102.3 is clinging to top spot, despite losing ground, followed by Nova 91.9 which climbed one spot to second.

FIVEaa also climbed a spot to third, increasing its share slightly, while the ABC was in fourth – falling from second in the previous survey.

Triple M remained in fifth spot. Fellow Southern Cross station, hit107, had a good survey, putting on 1.8 percentage points, to overtake classic hits station Cruise and move into sixth spot.

Hit’s improved showing was due to gains across the schedule, led by the breakfast and afternoon shifts.

ABC Radio Adelaide lost 1.2 percentage points of listener share. Perhaps revealingly, this was exactly the combined increase experienced by fellow ABC stations, RN and and ABC News.

Only Cruise lost more share, dropping 1.6 percentage points.
