I just checked the schedule and there is no Oceania Championships during the first set, this could make things hard for those nations if they want to qualify normally. Only Australia, New Zealand and Samoa sent athletes to the World Championships. Maybe they could make the Pacific Islands Email Tournament an eligible tournament. It doesn't help that the World Cup in China is being held at the same time. At best they could head to the Las Vegas Open during the Youth World Championships.
If not, Samoa stands to benefit from this while all the other nations will fight for likely 1 male and 1 female tripartite spot.
Also would the Oceania Championship, Commonwealth Championship and Pacific Games count as three results, despite being held at the same time? I know in 2017 they used the same lifts in both the Oceania and Commonwealth Championships.
