Rockliff, who was deposed as Lions skipper after the 2016 season, and forward Charlie Dixon are the new faces in Port’s seven-man leadership group.
Travis Boak will captain the Power for a club-record sixth consecutive campaign.
Rockliff left Brisbane at the end of last season to join Port and the club’s general manager of football Chris Davies says the 30-year-old has instantly demonstrated his leadership abilities.
“Tom has … within a matter of months shown our players that he’s a leader amongst them,” Davies said in a statement today.
“The coaching group too has been rapt with his character and commitment.”
Ex-Gold Coast Suns forward Dixon is in Port’s leadership group for the first time.
Midfielder Ollie Wines has again been appointed vice-captain with Brad Ebert, Hamish Hartlett and Tom Jonas retaining their spots in the group.
The sole exclusion from last year’s group is Jackson Trengove who has joined the Western Bulldogs.
