It coincided with the Shire being declared an RV Friendly Town by the Campervan and Motorhome Club of Australia.
The short stay area is near the corner of Jarrahdale Road and Kingsbury Drive and has a dumping point as well as space for about 30 self-contained RVs.
RVs can stay in the spot for free for up to 72 hours.
The site will be monitored by Shire officers to ensure people are abiding by the rules.
It is hoped businesses in the Jarrahdale area will experience the benefits of the new RV short stay area as road-based tourism in Australia is estimated to be worth about $7 billion per annum.
Serpentine-Jarrahdale Shire President John Erren said it would boost tourism in the Shire.
“RV travellers can now leisurely experience Jarrahdale as a tourist destination and all that it offers,” he said.
“We look forward to welcoming many mobile travellers to Jarrahdale.”
In order to qualify as an RV friendly town, the area must meet demands of travellers including access to a general shopping area, parking and access to a free dump point for toilet waste.
Former state representative and Camillo resident Phil Chad regularly travels around WA, visiting short stay locations.
He said the advantage of the Jarrahdale facility was its location close to the City.
“The advantage of it is that it is close to the city and close to the coast,” he said.
“Most travellers are oldies like myself and they very often need to get to hospital, specialists or chemists.
“It is the variation that makes this place very attractive.”
