Orville Kimutai Tures was swimming at Stockton Lake, near the town of Collie, at 3.15pm on Sunday when he went missing.
According to Australian police, despite the presence of other swimmers, no one was able to rescue Tures when he got into difficulty.
South West police officer Geoff Stewart reported that Tures was last seen swimming in the lake around 3 pm on that fateful Sunday.
“We received the report of someone that had gone missing whilst in the water at Stockton Lake, Collie,” Superintendent Stewart said.
Stockton Lake is a rehabilitated mine site and popular camping spot just outside Collie.
In 2019, a 22-year-old from the Congo named John Rashidi drowned at the same lake.
The region is known for its inland lakes, which, as Royal Life Saving WA spokesperson Lauren Nimmo pointed out, can conceal hidden dangers.
Tures, originally from Kapteren in Elgeyo Marakwet, had been in Australia since March of the same year, pursuing his studies at a university in Perth.
