Nashville Kangaroos Netball
Netball is indisputably the number one women's sport in Australia, and has both men's and women's teams of high caliber. Although the international game grew from the very inception of American basketball, its rules of play and court configuration make it a unique game. Wikipedia offers a good explanation here.
Of course, no written explanation can convey the spirit of a sport; the Nashville Kangaroos are among the growing number of U.S. organizations proud to host netball training, practice and competition for participants and spectators.
