“We’re delighted that Robbie, Hayden, James, Joel and Michael will continue their careers with the Swans for at least another year,” Sydney's Head of Football Charlie Gardiner told the club's website.
“Robbie has demonstrated an ability to play a number of roles at senior level and we expect James, Michael, Joel and Hayden to continue to develop and push for more senior opportunities next year.
“They’re all young, exciting, eager to learn and have bright futures ahead of them which is a great result for our football club.”
