The Katherine Camels remain the favourites to win the grand final of the Worksafe Big Rivers Football League.

The match begins at Nitmiluk Oval at 7pm.

The Katherine Times is planning to Facebook livestream the closing minutes of the big game tonight if you are not able to make it to the big match.

The Eastside Blues had a thumping win over the Beswick Bears in the preliminary final.

Both Camels and Blues have beaten each over during the regular season so the Camels take favouritism for the flag courtesy of their straight run into the grand final by beating the Blues.

Also, in another big sporting event, tomorrow from 7am the Top End Triathlon Festival is set to kick off at the Katherine YMCA and aquatic centre.

The triathlon will raise important funds to help CareFlight in its mission to assist sick and injured people across the Northern Territory who are in need of urgent medical care.

The triathlon is designed for individual competitors of any fitness level including complete beginners, as well as teams of two or three, and with special courses set for kids even little ones from five years of age will have an opportunity to compete.

Entry is $35 for individuals, and $30 for Triathlon Australia members.

Junior entries for kids of any age are $15.

All proceeds go to CareFlight Top End, and all funds raised are guaranteed to stay in the Northern Territory to directly benefit the NT community.

Registrations are now open online at http://katherinetriathlon.gofundraise.com.au.
