PORT Adelaide has re-signed assistant coaches Michael Voss and Chad Cornes, while senior assistant coach Matthew Nicks and development coach Aaron Greaves will leave the club at the end of the season.

As reported by AFL.com.au last week, Nicks has had interest from Greater Western Sydney as part of Leon Cameron's coaching team.

Greaves will return to Victoria.

"Matthew is looking to increase the breadth of his experience at another club and at the same time, we are mindful of the importance of introducing new coaches into our own program to generate new ideas and coaching philosophies," the Power's general manager of football Chris Davies said.

"Aaron is committed to his family returning to Victoria.

"Both Matthew and Aaron are contracted to Port Adelaide until the end of October and have invested a lot into making our club better.

"They are fully committed to continuing to the end of our 2018 campaign."

Voss joined Port Adelaide in 2015 as midfield coach and has extended his contract for a further two years.

Cornes, who enjoyed a decorated playing career at the Power and coached the Magpies in the SANFL in 2016 and 2017, will continue in his development role.

Nicks has spent eight seasons with the Power, starting as a development coach and moving through various roles before becoming senior assistant to Ken Hinkley last year, while Greaves has been with the club since 2014.

Davies said he had no issue with Nicks and Greaves remaining with the Power until the end of the season, despite admitting they could probably be coaching against them next year.

"They're contracted until the end of this year, and we believe both people are of sufficient character that they can continue to do their job and focus on our football club before they turn their attention to wherever they go next," Davies said.

It was a vastly different approach to that taken by Gold Coast, which stripped Tom Lynch of the captaincy and removed him from the football program after he informed them he wanted to move to a Victorian club at the end of the season.

"We've got to be good enough in today's day and age – there are plenty of players across the competition who know they won't be playing for their clubs next year," Davies said.

"We have been through a process recently where people get castigated for making decisions early.

"I'm not sure that's the right way to go and I'm very comfortable with both Matthew and Aaron doing their jobs for the remainder of this year.

"At the end of the year, we'll look at what our coaching panel looks like and what roles people will be doing."
