Following a successful trial period in NSW and the ACT, Woolworths Inverell will now offer the low-sensory quiet hour to customers.
The program is designed to reduce anxiety and sensory stress for customers with specific needs, including autism, by providing a quieter and less stimulating environment in store.
Autism Spectrum Australia estimates more than 300,000 (or one in 70) Australians are on the autism spectrum.
Woolworths Inverell will lower lights, turn down music and radio, and turn off oven buzzers for an hour every Tuesday between 10:30am and 11:30am.
Woolworths Inverell will join more than 260 stores nationally, including 87 in NSW and the ACT.
"We've heard from our customers there is a need in the community for a low sensory shopping experience in the area," Woolworths Inverell store manager Kim Fenton said in a statement.
"Off the back of successful trials, we're delighted to expand quiet hour to Woolworths Inverell for the benefit of even more customers.
"Our team takes great pride in ensuring the store is quieter and less stressful for customers who want to shop during quiet hour and we look forward to welcoming them in store."
The low sensory initiative was developed in consultation with disability service providers at Life Without Barriers.
Life Without Barriers Chief Executive Claire Robbs said quiet hour was a fantastic initiative that recognised people have different accessibility needs.
"It gives people a way to do their shopping and increase their independence in an environment that is not stressful and overwhelming to them."
