But in a surprising move, the 24-year-old has only signed a one-year contract extension.
“The best thing to do was to get the one-year deal sorted – I don’t want to go anywhere else,” said Oates on the club website.
“I did a one-year deal last season to prove that I deserve a bigger contract, not money-wise, but because I want to stay here for a long time and do whatever I can for this club.
“There’s been a lot going on in the back end of the season behind the scenes – and the best option was to clear my head, sign the one-year deal and back myself once again.”
Oates scored 18 tries in 23 matches for the Broncos in 2018 and will be looking to impress new coach Anthony Seibold in 2019.
