A Perth man who opened his home and heart to a homeless man after a chance meeting in a Northbridge park says he has been overwhelmed by the positive response to his random act of kindness.

Jonathon Strzina, who had just attended a music gig, met Tanzanian man Kin on Sunday night when he noticed him sitting alone on a park bench.

In a Facebook post (that by Friday had been shared 1800 times) Mr Strzina recounted how after sparking up a conversation with Kin, he learnt that Kin had only arrived in Australia the day before and had accidentally left his passport and the $300 he saved to start his new life in Perth on a bus.

"[My friends and I] sat down in the park and starting eating our chips and noticed this guy sitting on the bench across and I saw he had his bag next to him and wondered in my mind if he was homeless," he said.
