The club was originally formed by Ted & Maureen Riley after they viewed a Rugby league International game between Australia and New Zealand at Olympic Park in 1991 which left them wondering if Rugby League could take off in the Victorian township of Sunbury.

They then placed an advertisement in the local paper looking for other interested parties and on 17 September 1991 the first meeting of the club was held with twenty-six members.

It commenced its playing in what was known as the Rebel league and in 1994 began with one senior reserve grade team in the VRL Competition.

Many Sunbury locals were members of that grand final side with the community really getting behind the club's sudden rise under coach, Richard Puke.

At this stage the Sunbury Tigers have won four of the last eight premierships and may claim to be the current powerhouse of Victorian rugby league, as Altona Roosters and St Kilda Saints were before them.
