The Football NSW Women’s National Premier League (NPL) represents the highest level of women’s football in New South Wales. This league features 14 teams competing in both Reserve and First Grade divisions, with each team playing every other team twice in a round-robin format. At the end of the season, a Premier is crowned based on the league standings.

The Women’s NPL Club Championship, which governs promotion and relegation between NPL and League One Women’s, is determined by the points accumulated by each club's First Grade, Reserve Grade and GYL18 teams, excluding matches against the Football NSW Institute and Emerging Jets.
