It's the first time he's set foot in water since he almost drowned when he fell into a pool four years ago, shortly after arriving in Australia as a Tibetan refugee who had been exiled in India.
"I've put off learning to swim ever since, even though my friends tease me," Tsokney told CNN.
He's not alone.
Newcomers like Tsokney represent up to 40% of drowning fatalities, which is higher than the estimated 28% of the population who are born overseas, according to data from the Australian Bureau of Statistics.
It's a matter of concern for Australia, which wants to halve the number of water deaths by 2020. However, despite a campaign launched in 2016 by the Australian Water Safety Council, the number of deaths has risen year-on-year since 2015, with 291 fatalities recorded last year.
