Port Adelaide has confirmed media personality David Koch as the AFL club’s new chairman.

Koch has been a long-time Port Adelaide supporter and a joint number one ticket holder since 2007.

He says the appointment is an honour.

“There is no way I underestimate the challenges going forward, but I’m excited because I think that together we can make a difference and have a great impact as we guide the club through an incredibly exciting period,” Koch said in a statement on Tuesday.

“I have agreed to the role after taking advice from a great number of people, some of whom are every day members of Port Adelaide who sit in the outer week in and week out.”
