A Perth man who went missing in Bali after leaving the country with a Tinder date has been found, reportedly playing bongos in Thailand.

Josh Goudswaard was reported missing this week after not being heard from since November 1 and family and friends held grave fears for his safety.

But according to Mr Goudswaard's friend Aaron Smith he was found alive by an American tourist on a Thailand beach on Thursday.

Mr Smith announced he had been found in a post on social media, with New Zealand Police later confirming he was no longer considered a missing person.
