An Indian man on a holiday trip to Melbourne, Australia died in a horrific drowning incident at a popular waterfall in the Grampians National Park in western Victoria as witnesses helplessly tried to reach out to save him.

The man was identified as 27-year-old Harmanjot Singh Walia of New Zealand who had gone on a short holiday trip to Australia, SBS Punjabi reported.

The incident happened Rockpool at MacKenzie Falls at Zumsteins, near Stawell on Boxing Day when Mr Walia, his wife and two other friends went for a swim.

Witnesses at the scene of the accident told SBS Punjabi that bystanders desperately tried to rescue him Walia, but he was too far to be reached.

“Some swimmers who heard our screams came to help but all in vain. It was too dangerous to go under the fall which seemed like a very dangerous place,” the witness told SBS Punjabi.

“It was a very tragic accident. Harman swam to the dangerous end of the fall and got stuck under it behind the rocks. It was a stupid thing to do this adventure. It’s too late to reflect on the circumstances leading to his death,” the witness added.

The incident happened around 6 p.m. on Wednesday, December 26 but the police divers were only able to recover the body around 1 p.m. on Thursday, December 27 morning

Witnesses at the scene of the accident told SBS Punjabi that the area was poorly indicated with the danger-signages.

The witness also mentioned that it took three hours for the rescue team to start the body search which was already too late for the victim to be saved.

“People at the scene struggled to contact rescue authorities due to limited telephone reception in the vicinity,” the witness added.

It is said that four people have drowned in the area in 2004 and there was another incident in January 2018, less than 12 months ago.

Mr Walia hailed from Patiala, Punjab in India and recently received his work permit in New Zealand. He came to New Zealand three years ago.

“His tragic death has shattered hopes and dreams of his family back in Patiala, Punjab,” the witness said.

“He was looking after his family’s financials. His mother recently had surgery after a severe brain haemorrhage.

“He will be remembered as a hard-working, fun-loving man who single-handedly supported his family,”

People have started making donations for the victim in Australia.

SBS Punjabi reported that this is the fifth drowning incident in Australia since Christmas Eve, and fourth in Victoria alone.

Last week, three Indian nationals drowned at an unpatrolled beach near Coffs Harbour in NSW.

The death has been referred to the coroner. More to come.
