Eleven countries are participating in the powerlifting competition.
Powerlifters compete in three disciplines - squat, bench press and dead lift, each designed to measure different aspects of strength.
Athletes get at least three attempts at each and the winner will be determined by the highest weight total of the best lift in each discipline.
In 2015, hosts Papua New Guinea were dominant, particularly in the women's divisions where they claimed six of seven possible gold medals.
All eyes will be on whether they repeat the feat in 2019.
