Woolworths Delacombe store manager Rick Jones said there had been little fuss from shoppers on day one of the plastic-bag ban.

“It seems the majority are buying their reusable bags which they’ll then continue to use,” Mr Jones said.

”We’ve been talking about it for months and it will be legislated soon, but we haven’t had any negative feedback so far.”

Coles will stop supplying single-use plastic bags on June 30.

“From the beginning, we felt strongly that this was the right thing to do and we’re really pleased to see customers are behind the change as well,” said Woolworths chief executive Brad Banducci.

“What we’re trying to do is encourage more customers to bring their own reusable bags when shopping, so we can prevent plastic bags from reaching our waterways and reduce the overall production of plastics. 

​About 1.6 billion single-use plastic shopping bags are used in Victoria each year.

Both supermarket giants will also offer flexible plastic recycling options in all outlets via the REDcycle program meaning customers can return soft plastic packaging used on produce, biscuit packets, frozen food bags, rice and pasta bags, confectionery packets and shopping bags, which is turned in to recycled plastic products such as outdoor furniture.

National Plastic Bag Campaign coordinator Jon Dee said there would be an adjustment period for most shoppers who would also need to find alternatives for previous plastic bag use in the home.

He said one of the main secondary uses of supermarket shopping bags was as bin liners.

Rather than using shopping bags to line bins, Mr Dee suggested rubbish could be put straight in to bins with bins washed every few weeks. Food and compostable items should go in compost bins, and recyclables in to recycling bins.
