The concert in Warren on Friday may also put the finishing touches to the town’s Window on the Wetlands (WOW) Centre , called a “key gateway” to the iconic Macquarie Marshes.

RiverSmart Chief Executive Officer (CEO) Dr Bill Phillips said the previously-sponsored floating classroom had involved a cruiser taking school students onto the Macquarie River for lessons on river health.

“That’s something we would love to restart,” he said.

Dr Phillips said the completion of the WOW centre would allow the “education, recreation and cultural” facility to get down to business.

“The things we want to do include taking guided tours into the Macquarie Marshes so we can show people why they are deserving of some of the water,” he said.

Another night by the billabong is Ms Storer’s second fundraising concert for RiverSmart.

The first in April 2014 drew almost 400 people

On Wednesday Dr Phillips was hopeful of a crowd at the Warren Sporting and Cultural Club on Friday night despite a late harvest and “a lot of people still on tractors”.

Ms Storer, the recent recipient of a 2016 ARIA ( Australian Recording Industry Association) award for best country album, will perform with her brother and “Warren local”, Greg.

“We're also pleased to advise that Dubbo local Davesway, aka David Daly, will be Sara's support act on the night,” Dr Phillips said.

The CEO said Friday’s concert was a “major coup for the central west”.

“While tickets are still available, we’ve seen a surge of interest in attending since the announcement of the ARIA award,” he said.

On Tuesday night Ms Storer was nominated for five golden guitar awards at the 2017 Tamworth Country Music Festival. She already has 19.

On her Facebook page Ms Storer has told why she supports RiverSmart.

“It’s all about saving our rivers,” she said.
