The National Second Division (NSD), also referred to as the National Second Tier (NST), is a proposed Australian national second-tier men's soccer league, to be run by Football Australia and the Association of Australian Football Clubs (AAFC). It has been suggested that the league will consist of 12 to 16 teams, the bulk of which would be drawn from the existing National Premier Leagues competition. The league's focus would be to improve player development and to boost the overall standing of the game in Australia by generating new interest and revenue.[1]
