After five days in the Kakadu wilderness, 31-year-old French tourist Yann Buriet has been found alive.

The disappearance of Mr Buriet — who was last seen on Saturday in the car park at Gunlom Falls, a popular tourist campsite in the southern part of the park — triggered ground, air and dive squad searches.

It’s unknown what Mr Buriet’s health condition is, but the ABC understands critical care aeromedical service CareFlight had not been tasked to respond after he was found walking out of bushland this morning.

He’ll tell his story and also undergo a health check, but it appears he walked out himself so he may still be suffering from exposure,” Superintendent Hege Burns told the ABC.

Mr Buriet was last seen by park rangers at Gunlom Falls on Saturday, when he told them of his plans to camp and bushwalk in the area.

But when his van was spotted untouched on Tuesday, rangers raised the alarm and a major search was sparked.

‘‘I think he’s calling his mum now and we’re obviously going through the official connections through the French consulate,’’ Superintendent Burns said.

Helicopters and ground crews were used in the search, which spanned kilometres around the Gunlom Falls site.

I think right now we’re just happy that he’s found,” Superintendent Burns said.

‘‘It’s such a timely reminder for anyone planning to visit our beautiful national parks to please be prepared, please plan, but most importantly let someone know your plans and when you are expected back.’’

Kakadu’s recent history marred by tourists in trouble

Earlier in August, a 52-year-old woman who was three days into the five-day Jatbula trail walk, north of Katherine, had her leg trapped by a dislodged boulder ‘‘which was estimated to weigh several hundred kilos’’, CareFlight said in a statement.

In Central Australia, German tourist Monika Billen was found dead about three kilometres from Emily Gap, a popular tourist site near Alice Springs, after going missing for two weeks in January this year.

Earlier that year in January, American actor and gay rights activist Matt Palazzolo died while hiking Mount Sonder in the West MacDonnell Ranges in extreme heat.

Meanwhile, in February 2017, German couple Wilfred and Gisela Thor, aged in their 70s, were found dead from dehydration and heat stress after they wandered 17 kilometres off a marked walk at Trephina Gorge in Central Australia.

For everyone, know your own capability, always prepare, talk to your family and friends, let them know where you’re going and when you’re expected back — it’s really important,” Superintendent Burns said.

‘‘Also touch base with the rangers out in the park because they’re the subject experts and they’ll let you know the dos and don’ts as well.’’
