The legality of toilet paper orders in Australia can vary from state to state.
The state of New South Wales has the largest collection of such orders, followed by Victoria and Queensland.
“We are looking at our toilet paper supply chain as a whole, and the toilet paper is a key item of that,” Mr Mertz said.
It’s a very, very big issue in our community, and we have a lot of concerns around this issue.
The NSW government is looking at how best to protect consumers from counterfeit toilet paper and also whether there should be laws to regulate the supply chain, he said.
The government’s Department of Health said toilet paper could be found in stores across the state and in supermarkets in some suburbs.
A government spokesman said it had been contacted by a member of the public who reported toilet paper missing from the supply line.
“We have also contacted the Australian Taxation Office and will provide further information in due course,” the spokesman said.
“The NSW Department of Human Services will continue to work with our customers and businesses to ensure that they are safe and secure with toilet paper.”
Australia has about 3.8 million people who have lost or stolen toilet paper.
Last year, an average of 2.7 million Australian households lost or had a stolen toilet, and about 8.2 million lost or were stolen in NSW.
Mr Mertsz said there were several ways in which toilet paper can be stolen, including from a family member, from a person with a disability or from someone who is intoxicated.
Australian Consumer Law says anyone can be fined up to $50 for not providing a toilet paper order, while some states have also introduced fines for not supplying the right kind of toilet roll.
In Victoria, fines can range from $100 to $300 for a failure to provide a toilet roll, while in Queensland a penalty of up to 500 dollars is possible for failure to supply a toilet in a non-approved quantity.
