With netball drawing bigger crowds than some National Rugby League games, administrators are considering moving matches to bigger stadiums and changing the structure to keep more teams in contention for the finals.

The moves, also designed to be more friendly for broadcasters, come as the sport's flagship competition, the ANZ Championship, enters its final stages.

Crowds across the 10-team competition, which features five teams each from Australia and New Zealand, are up about 8 per cent compared with the 2013 season and television ratings have increased about 15 per cent.

In May, the NSW Swifts attracted a record 10,000 home crowd, outstripping two RL matches played in Sydney on the same weekend. The Melbourne Vixens, which finished first on the ladder this season, have attracted crowds of up to 8000 and have more than 3000 season-ticket holders.
