McDonnell’s contract with Saints finished at the end of the 2016 Super League season, with the Red V’s semi-final defeat to Warrington.
McDonnell told Love Rugby League he is not ruling anything out, including a move to another Super League club in 2017, at this stage.
“I have not made any decisions as of yet as to where or if I will be playing next year though,” he admitted.
“I’m just really looking forward to getting home for the off-season to see the family.
“I wouldn’t rule out a return to Super League it would just have to be worth it for myself and my family.”
The Australian made 18 appearances and scored seven tries this season for St Helens.
McDonnell said he was pleased with his form for the club this year after coming back from serious injury.
“I’m happy with my form and feel I got back to my best football after my end of season surgery last year,” the outside back said.
“It was a challenge for myself in the off0season and the start of the year to recover and come back from an Achilles repair, though the physio team at St Helens were amazing and I worked my ass off to get back to the field as quick as I could and didn’t look back.”
McDonnell has represented the Wolfhounds on three occasions in the past.
