After more than 15 years together, ABC Radio Adelaide Breakfast duo Matthew Abraham and David Bevan will soon part ways.

Abraham announced to listeners this morning that he would leave the popular show next Friday, June 30.

His departure marks the end to one of the ABC's most successful partnerships, with Abraham and Bevan first broadcasting together in 2002.

Matt and Dave, as they are affectionately known, began in the Mornings timeslot.

The pair soon became famous for their robust and no-ground-given approach to political interviews.

Record ratings run

Abraham and Bevan achieved record ratings success for the ABC in Adelaide, with 34 number one wins.

They will finish on their 13th consecutive number one win.

"This has been a really hard decision," Abraham said. "I'm stepping away from the microphone; I'm stepping away from radio."

ABC Radio Adelaide manager Graeme Bennett said the duo had become a quintessential part of the local media landscape.

"Since their move to the notoriously competitive breakfast timeslot they have dominated the local agenda," Mr Bennett said.

"Matt leaves the ABC at the top of his game, with a deserved reputation as one of the finest journalists the state has produced."

Bevan will continue to host the ABC Radio Adelaide Breakfast program solo.
