Host of the event, the Walgett Aboriginal Connection rugby league team , is promising a "real spectacle".

"There will be strong competition in Dubbo with teams coming from across NSW, Newcastle and parts of Sydney," said its spokesman Geoff Simpson.

"The Walgett Aboriginal Connection would like to welcome all Dubbo people and as many fans as possible from nearby towns to come and enjoy the games over the weekend and to enjoy the great tournament atmosphere."

The knockout competition will run for four days with the finals scheduled for Monday October 5.

"There will be competitions for under 12s 15s 17s women and men so across the four days of competition there will be plenty of chances to see some great rugby league in action," Mr Simpson said.

Walgett Aboriginal Connection became host of the 2015 knockout after winning the event in 2014.

It has joined forces with Dubbo City Council to "ensure the success of the event".

"The NSW Aboriginal Rugby League Knockout is another great sporting event for Dubbo," said Dubbo City Council city promotions and events supervisor Lana Willets said.

"Full-day tickets will cost just $10 and children under 12 are free, so it is a great opportunity to watch some top-class rugby league from the comfort of the Dubbo Apex Club's Caltex Park grandstand."

Ms Willets said a free bus would pick up passengers from various motels and businesses throughout Dubbo "to make transport easier".

"This is an opportunity to take the family to the footy, see some leading rugby league players in action and have a great day out," she said.

Walgett Aboriginal Connection is made of players "connected by hometown, by blood and by close friendship".

It has been a dominant force in the annual NSW Aboriginal Rugby League Knockout.
