Locally-based Greyhound Breeders, Owners and Trainers Association (GBOTA) director Geoff Rose said he was notified last week that the Gunnedah track had been chosen for the first heat of the Million Dollar Chase on August 31.

"What it will bring into the economy here will be unbelievable. The whole town will benefit," Mr Rose said.

"You've got people coming from everywhere. If they're driving, they'll be staying in the hotels, they'll probably be going to the club, they'll be going to the restaurants. They're not going to just come and go overnight.

"It's something really big for the town. No two ways about it."

Mr Rose said it was the first time the heats had been held outside of metropolitan areas, with six of the 14 races in NSW to be hosted in regional centres.

"They tried to put it out into regional areas to stimulate the economy," he said.

It's not the only good news for the club - if it can attract the funding, the club can tick off its last big renovation project after Gunnedah shire councillors unanimously passed a development application at last week's meeting.

In 2020, the club is looking to demolish and replace four officials boxes and amenities blocks, extend the roof of the main building and add new onsite parking facilities. The boxes house the judges, stewards, camera, race caller and lure operator.

Mr Rose said the boxes and amenities were built in the early 1950s and an upgrade was well-overdue.

The officials boxes are bare wood and one of them is even open to the elements so tech is set-up and packed up after each meet.

The changes will cater for the crowds and provide a weather-proof environment for the tech gear essential to race meets so officials can provide the best "vision" possible.

"If you're going to provide vision worldwide, you've got to have the facilities," Mr Rose said.

"It will bring us up to date with everywhere else.

"We'll all know the difference when it's done."

Cr Rob Hooke was particularly supportive of the upgrade when it went before council last week.

"I'd just like to enthusiastically be the seconder of this motion because the greyhound racing fraternity, and especially locally, was on its knees not very long ago because some legislation went completely awry and it's so good to see them back on their feet again," he said at the meeting.

"They're a very important part of this community and I think it's just wonderful they've got this proactive committee together to put this development to task and I think it will be great to see the thing up and running again."

It has been three years since former NSW Premier Mike Baird announced a ban on greyhound racing in NSW. The proposed ban was reversed three months later in October 2016.
