Swimming in heat two of the Women’s 50 Butterfly, McCarthy finished in a time of 30.27 seconds.
“It was just off my Personal Best so it wasn’t as I hoped it would be, but it was alright,” said McCarthy.
She said in terms of improvement from the Championships, she is now able to hold her stroke better for the 50 metres and push harder in the swim.
“It’s been a great experience. So nice to come from Papua New Guinea and come straight here and compete. It’s a really nice experience,” said McCarthy.
