Brennan joined the Jets ahead of the 2015/16 season on a two-year contract.

The Tasmanian-born winger/striker made five appearances in the A-League during his time in the Hunter.

Brennan has returned to Tasmania with a view to continuing his professional career elsewhere.

“Newcastle Jets thanks Brennan for his contribution to the Club since 2015 and wishes him well in his future pursuits,” the club said in a statement.
