Canada also has a much bigger population than Australia (41.5 million versus 28 million). The attendances are fairly similar when you put into perspective the population of each country.
The NSL works but it’s a different situation. Canada had no national women’s league before 2025, nor did it have any NWSL teams (unlike the Canadian MLS teams and Canadian teams in most other American Major Leagues). We’ve had one since 2008. There’s little point to disbanding the existing teams that’ve been playing for 18 years.
