The supermarket giant is preparing to go single-use plastic bag free nationally from June 20.

The change will see the removal of 3.2 billion lightweight plastic bags from circulation across Australia each year.

Woolworths Ulladulla and Woolworths Vincentia operations manager John Maloney said he was proud to help create a “greener future” for Australia by removing single-use plastic bags from the stores. 

“We appreciate that it will be a big change for our customers and will do what we can to support them through the transition to make it as smooth and simple as possible,” Mr Maloney said.

In the lead up to June 20, there will be increased signage in-store and at checkouts reminding customers of the date change.

“Our local team members will chat with customers regularly to ensure they know about the upcoming change and the various options available, as well as sharing tips on how to remember to bring reusable bags when shopping,” Mr Maloney said. 

“We know our customers will have their own ways of remembering bags and we look forward to hearing how they are planning for the change as well.”

Customers will have the option to bring in their own bags or will have access to purchase a range of reusable bag options starting from 15 cents.

Planet Ark CEO Paul Klymenko said Woolworths' move will have a really positive impact on the environment and he was confident the local community will embrace the change.

“Single-use plastic bags have become a huge problem for Australia’s oceans and waterways where they cause significant harm to marine life, such as turtles and whales,” Mr Klymenko said.

“They also don't breakdown in landfill and require significant resources to manufacture in the first place.

“Experience in countries like the UK and Ireland shows that the introduction of small charges on plastic bags can end up reducing plastic bag usage by up to 85 percent as locals embrace reusable alternatives.”
