For one hour each week, the stores will switch off the radio, dim the lights by 50 per cent and reduce register volume in a move to help shoppers who struggle with heightened sensory environments.
The initiative saw an overwhelmingly positive response from Victorian shoppers during trials earlier in 2017.
No trolley collections will take place during Quiet Hour, while announcements will only be made in emergencies.
The 'Quiet Hour' will take place between 10.30am and 11.30am every Tuesday.
Aspect's community engagement and operations manager Linzi Coyle told Fairfax, 'People on the autism spectrum often have difficulty processing sensory information and can find sounds, light, smell, touch and taste overwhelming.
'Together with Coles, we're achieving a 'no-judgement' shopping space where people on the spectrum and their families can feel comfortable and welcome whilst grocery shopping.'
Several shoppers have already announced their excitement and gratitude toward the new initiative.
