The playmaker arrived in the nation’s capital in 2015, where he has managed 80 games for the green machine and picked up the Dally M five-eighth of the year in 2015.
Austin will look to further expand his rugby league career after signing a reported three-year deal starting from 2019 with the Wolves, who currently sit 4th on the Super League ladder.
Austin has thanked the Raiders for giving him the opportunity to be able to play some of his best footy for the green machine.
“I’d like to thank Ricky, Don and the club for presenting me and my family with the opportunities they have over the past four years,” Austin told raiders.com.au.
“Thanks to my teammates and the Canberra members and fans for embracing me as one of their own. I hope to be remembered as a guy that gave his all in green.
“I look forward to playing the best footy I can for the remainder of the 2018 season.”
Coach Ricky Stuart has given Austin his best wishes for his future endeavours and says the club have not ruled out signing him back in the future.
“From a personal point of view, I wish Blake, Gillian and his family all the best for a new start,” Stuart told the club’s website.
“Blake was a big part of the club’s resurgence as an attacking team and that will be a huge bonus for Warrington.
“The door at the Canberra Raiders is never closed in regards to Blake and his family. This was a salary cap decision by the club and we genuinely wish him all the best.”
