GREATER Western Sydney chief executive Dave Matthews has signed a three-year contract extension to remain at the club.

Matthews' current deal at the Giants was due to expire at the end of this season, but he'll now be in charge until at least the end of 2021, after starting his role before the club entered the AFL competition.

The news comes after senior coach Leon Cameron and head of football Wayne Campbell committed to the club until the end of 2020 last season.

Under Matthews' leadership, the Giants have been able to re-sign a host of their talented young stars under Cameron, build an impressive training base at Sydney Olympic Park, and launch teams in the AFL Women's competition and the domestic netball league.

The club has also forged a strong relationship with the Western Sydney community and the ACT, and gathered plenty of corporate support in both areas.

GWS chairman Tony Shepherd said the club's decision to re-appoint Matthews wasn't a hard one.

"Dave has been an outstanding leader of our club and is the right person to continue to lead us as chief executive in the next phase of the club's development," he said.

"During the seven years of David's leadership at the Giants we have grown to be an important member of the communities of Western Sydney and the ACT. We are now a major player in the most competitive sporting market in the country, if not the world. And this is from a standing start over seven years ago. 

"We have three great teams, strong commercial support, fantastic facilities, a passionate supporter base and an organisational culture that is second-to-none. 

"To have our CEO in place for a decade, alongside our long-term coach Leon Cameron and general manager of football Wayne Campbell, demonstrates the strong and stable leadership at the Giants which is essential to long-term, sustained growth. 

"While we have grown significantly in recent years, we are bullish about taking even greater strides in the coming years."

Matthews said he's excited to continue overseeing the Giants' development as a club both on and off the field.

"The Giants have experienced a period of significant growth in recent years and I'm excited to be leading the organisation into the next phase of growth," he said.

"We've developed from very humble beginnings in 2012 to today having three elite teams that proudly represent the communities of Western Sydney and the ACT.

"In a relatively short space of time, we've grown a loyal and passionate fan base that is helping write the history of this club and indeed Australian Football.

"With the leadership of a strong and stable board led by Tony Shepherd, we have developed a club filled with great people who are hungry to continue to grow the Giants and achieve sustained success."
