Commonwealth Games silver medallist Kaity Fassina will compete in the weightlifting and Will Sargent is contesting the sailing.

Australia will be represented by 58 athletes in the Samoan capital, Apia, for the 16th instalment of the Games which bring together 5000 athletes and officials from 24 Pacific nations to compete across 27 sports.

With world rankings key to qualification for the 2020 Olympics, competitors in athletics, taekwondo and weightlifting will be eyeing off valuable ranking points.

Fassina will be among athletes from 19 nations taking part in five days of competition at the Faleata Sports Complex.

Sailing will feature for the 13th time at the Games with 11 countries contesting the hobie cat, laser and laser radial events at Mulifanua.

"The Games will be a smaller racing fleet, so I think the race is going to be a bit more tactical than the bigger fleet stuff," Sargent said.

"It will be interesting with the trade winds, such a different environment to Australia. I have started hiking, which is not too much fun, but the increased strength and weights should equal more speed on the water."

The sailors trained for the weather, breeze and wave conditions they are likely to face in Poland.
