there is so.Australia has no minimum total for a master in order to qualify for events such as the commonwealths or asia/oceanias however its probably not in your best interests to get up there with a 300 total,i think common sense would prevail,you would at least need to be competitive in your category.
I know NZ has a fixed total but its real easy to qualify however that does not mean you will be picked,thats up to the discretion of the selectors.However in terms of gaining team points,i think filling up slots would obviously be to the teams advantage.
