The women and juniors kicked the action off at 9.15am, and it continued all day giving fans a fantastic opening to what will be a bumper four days of top-shelf rugby league.

Koori Knockout co-ordinator Mark Deweerd was rapt with how the first day went, but knew it was only the beginning of an event that got bigger and bigger every year.

"It's been a great first day and the carnival is running to plan," he said.

"We have a huge crowd, the footy has been great and the businesses and people of Dubbo have been very welcoming.

"It's great to have all the services providers here promoting their programs, and for them to have access to everyone that is here.

"I've been involved with the knockout for 15 to 20 years and it gets bigger and better every year."

Along with some cracking skills on display on the field, a total of 40 stalls were in operation providing information, services and programs for those in attendance.

The NSW Government Office of Aboriginal Affairs director of regional co-ordination Steven Gal thought the Koori Knockout was a fantastic opportunity for organisations to get their message across to their target market.

"The knockout is a great chance for Aboriginal people to come together," he said.

"It is great for us and other services to build a relationship under these circumstances.

"A lot of people are more comfortable having an informal chat at the footy whereas if we were in an office some people aren't as forthcoming."

Across the four days, the Koori Knockout is expected to draw about 15,000 people to Dubbo which will inject an estimated $6.6 million into the local economy.

The Knockout continues on Saturday with the men's games kicking off at 8.30am, and will run through Sunday and Monday.
