The Kiama Rugby Sevens will not just deliver nearly 12 hours of high-octane sporting action on Saturday but a seven-figure windfall for the local economy.

Despite the wet weather, Kiama Council on Friday gave tournament organisers the go-ahead despite forecast of more wet weather possibly being on the way on Saturday.

Running for the 54th year, the iconic annual event kicks off at Kiama Showground and Chittick Oval at 8am on Saturday with matches running on both fields throughout the day.

A helicopter will deliver the trophies late in the afternoon before the semis and finals are held for the men’s and women’s country divisions, as well as the Bowl and Plate categories leading into the women’s final at 6.30pm and the premier men’s decider at 6.50pm.

The winning teams in the two main finals receive $6000 each with the runners-up pocketing $3500.

Tournament director Mark Bryant said Saturday’s event was shaping up to be one not to be missed.

“Everything is done preparation wise, we've filled 44 teams back in November and then we had a few teams pull out and we've had to adjust.

“The grounds are coming up quite well. You can't get a room in town because of all the teams - everything is full.

“The weather is looking like it's gonna be about 23 degrees and overcast which is actually perfect weather for rugby. You don’t want it too hot.”

It’s not just a sporting event but a driver of economic benefit to Kiama.

“Through Destination Kiama, we do a post-event report and we bring in $1 million to the town for the weekend. For all the licensed outlets, this is the biggest night of year for them,” Bryant added.

And the standard of play is set to be sky high with Shute Shield teams and a squad from the Brisbane GPS lining up.

“Manly won the Hamilton Sevens, Warringah Rats are always up there, UTS Gordon will be really strong. Southern Districts are coached by Kiama’s own former Wallabies player Scott Fava so they will go well.

“GPS Brisbane are not going to travel all this way and not give it a shake.

“In the women’s, Manly and UTS Gordon are always up there and one of the dark horses this year will be Hunter Wildfires from up in Newcastle.”

Illawarra premiers Kiama will be taking part in the country division with Wagga Wagga Reddies, Orange Emus and Northlakes likely to be their main competition.

“The good thing about the country cup is that it’s pretty even and it could come down to a ref’s call or a bounce of the ball,” Bryant said.
