[1][5] In 1919 the Wyong and District Rugby League was formed which included teams from Jilliby, Kincumber, Nords Wharf and Yarramalong.

[1] Wyong were unable to consistently field a team during the war years with some players choosing to play with Ourimbah.

Wyong teams continually finished on the bottom of the ladder in all grades and eventually withdrew from all competitions in 1958 due to lack of interest, player unrest and poor administration.

It was one of the most significant appointments in Wyong's history as Breen instilled a style of play and culture that was to lead to ongoing success in the '70s and '80s.

[6] Breen arrived at Wyong after an extensive career playing and coaching in North Queensland, NSW Country and with Brisbane Souths and Eastern Suburbs.

[1] Another highlight of the decade occurred in 1986 when the Wyong under 16s, coached by Mick Kent, completed their time in junior football with nine successive premierships.

Tony Newbury, Adam Aiken, Steve Carter, Darren Barratt, Lee Sharp and Damian Kent played in all grand finals.

[1] The '90s began well with former Canterbury half-back, Mal Creevey, as coach, leading the team to a well-deserved premiership in 1990 after the three successive losses.

[citation needed] After defeating the Tweed Heads Seagulls in the 2002 Country Challenge Cup, then winning premierships in 1st and 2nd Grade and another club championship Wyong made the decision in 2003 to join the Newcastle Rugby League Competition.

Under new coach, Paul Stringer, Wyong withdrew from all Central Coast competition in 2007 and made the NRLC Grand Final, only to be beaten by Lakes United.

At the end of the 2012, season Wyong decided to pull out of the Newcastle competition and enter a team in the 2013 NSW Cup.

[12] In 2014 the Wyong Roos, with Rip Taylor replacing Paul Stringer as coach and strengthened with the signing of Mark O'Meley, won 13 games to make the finals, eventually finishing 7th.

[17] In March 2018, Wyong announced that their partnership as the Sydney Roosters feeder side would be ending at the conclusion of the season.

[20] In November 2018, it was announced that Wyong would not be competing in the 2019 Intrust Super Premiership NSW season with the South Sydney Rabbitohs taking their place.

[6] A licence was obtained in 1972 and the club was officially opened by the President of the Australian Rugby League in June, 1973.

However, the development and sale of this land and with the support of banks and creditors the club was able to overcome all its financial difficulties, enabling it to grow and expand rapidly.
