RULES banning small nature-based camping areas within 50km of West Australian caravan parks have been scrapped.

Changes to the Caravan Parks and Camping Grounds Regulations 1997 will now allow more of them throughout the state.

WA has 25 licensed nature-based parks ... small-scale tourist camping areas in natural landscapes.

Local Government Minister Tony Simpson said the new regulations required nature-based parks to meet consistent minimum standards wherever they were.

This would provide assurance for holidaymakers and encourage greater investment in the industry.

"The new regulations define a nature-based park, where there was ambiguity before," he said.

"They improve the minimum health and safety requirements and impose a responsibility on the owners to advertise limited facilities.

"Visitors will have greater clarity about what to expect."

He said operators wanting to establish a nature-based park would now have to submit a plan detailing how it will be designed and managed and the facilities available.

"There will be more surety about what to expect from nature-based parks. This is better for everyone ... local governments, operators and holidaymakers," he added.

The changes were the result of a three-month consultation by the Department of Local Government and Communities with local governments and other stakeholders.

WA has more caravan, camper-trailer and campervan registrations than any other State, with 30 for every 1000 people.

The state government has launched a Parks for People Caravan and Camping initiative, a $21 million investment over four years.
