The event will be held within Blacktown for another three years after the council committed to financial support with the organisation last week.

The carnival brings together the school junior league community from across the state for three days of competition.

Each year more than 3000 students take part in the tournament watched by more than 5500 spectators.

The NSWRL's Western Sydney Rugby League Academy organises the carnival, which has been running for 68 years.

Through council support, the NSWRL carnival games will be played at Whalan Reserve.

The council will waive the fees for the use of the reserve and provide a further $5000 a year in financial support to help the academy with various costs associated with its organisation.

``The carnival is a great opportunity for young rugby league players to come together and build on their teamwork and development skills,'' Blacktown Mayor Charlie Lowles said.

``The competition brings a significant boost to Blacktown's economy each year with many participants and their families using local accommodation, restaurants and tourist attractions during their visit.''
