Sydney-based Seven Network identity David Koch is reportedly set to be named AFL club Port Adelaide's new president.

Koch, host of Seven's breakfast program Sunrise and with a background in finance journalism, has been anointed the Power's next leader by both Fairfax and News Limited websites.

Adelaide newspaper The Advertiser's website says the Power are set to adopt five new board members including Koch.

The Age also reported Koch would be named president on Tuesday, but that an announcement on ex-coach Matthew Primus's replacement was not expected.

A Port official said on Monday the club would not comment about the speculation.

Power president Brett Duncanson announced in August he would stand down in December.

Koch is the Power's No.1 ticket holder and, if the report is correct, would follow in the footsteps of fellow television personalities and AFL club presidents Eddie McGuire (Collingwood) and James Brayshaw (North Melbourne).

While on-field success has been limited in the past few seasons, Koch's biggest challenge would be turning around the club's perilous financial state from afar.

He would also offer a profile beyond South Australia.

The AFL Commission and the SA Football Commission are helping fund the debt-ridden AFL club.
