According to The Courier Mail, Oates received offers of up to $600,000 per season from the clubs trying to lure him out of the Broncos.
However Oates’ manager Geroge Mimis told the paper his client would re-sign with the Broncos before the November 1 deadline.
“A new contract for Corey is imminent,” Mimis said.
“We have had very respectful and promising negotiations.
“Both parties are keen to continue a successful relationship. Corey’s preference was to always stay at the Broncos.”
Oates has played 120 games for the Broncos since making his debut in 2013.
