The precautionary move is designed to support appropriate social distancing in stores at the weekend and ensure all customers have access to the products they need, the supermarket giant reports.

Woolworths continues to see good stock levels flow through its warehouse and into stores.

It comes after active cases in Victoria almost doubled in a week, and the state faced a new lockdown.

The product that flew off supermarket shelves at Dubbo and across the country in March is back in the spotlight.

"We've regrettably started to see elevated demand for toilet roll move outside Victoria in the past 24 hours," Woolworths Supermarkets managing director Claire Peters said.

"While the demand is not at the same level as Victoria, we're taking preventative action now to get ahead of any excessive buying this weekend and help maintain social distancing in our stores.

"We have ordered more than 650,000 additional packs of toilet roll into our network, which is an increase of more than 30 percent on our usual volumes.

"We have plenty of stock for all of us, so we encourage our customers to buy only what they need and think of others in the community as they shop this weekend.

"If customers already have enough toilet roll at home, there is no need to buy more.

"The sooner we see buying patterns return to normal levels, as was the case throughout May and most of June, the quicker we'll be able to wind back limits."

There are no other product limits other than toilet paper and paper towel outside of Victoria at this time.
