I don't think you will find that there are many people in this team who are likely to have to worry about Aussie representation other than for the WUG team. The standard would be about WNBL standard, which is quite good, but there would be very few girls in the team in contention for an Australin berth.
Its a great opportunity for people who are just out of reach of Australian senior teams to be able to represent their country, and take a step up to playing at international level, in a major world tournament.
It has been rated by people in various sports as a tougher competition than the commonwealth games.
