Young played 24 games for the Suns in his past two years at the club, after 76 for Port Adelaide in six seasons prior.
Crossley played 10 games in 2018 although he didn’t feature this season, while Wigg didn’t make a senior appearance for Gold Coast.
“On behalf of everyone involved with the football club, we would like to take the opportunity to thank Aaron, Harrison and Brayden for their commitment and contribution to the Gold Coast SUNS,” Gold Coast’s General Manager – Football Operations Jon Haines told the club’s website.
“Harrison is a much – loved member of the playing group who has unfortunately not been able to demonstrate his full capability due to a series of significant injury setbacks. He has demonstrated great resilience during this period and has never wavered from his ability to bring energy and care to the group”.
“Aaron has made a significant contribution both on field and importantly amongst our playing group since joining from Port Adelaide. He is highly regarded by his teammates and the club and we wish him all the best with his future endeavours.”
“Brayden is a local Gold Coast product and someone who has progressed through the Gold Coast Academy pathway. Brayden has had to navigate his way through an extremely challenging period recently, and he has conducted himself with class and maturity throughout. As a club we will continue to support him and his family wherever possible”.
The Suns also confirmed they would move Josh Schoenfeld from the senior list to the rookie list, and have delisted him with the commitment to picking him back up in the November 29 Rookie Draft.
