the a-league is currently on 4 straight years of increased attendances
the nrl....3 straight years of decreases
RL averaged 14.2k in 1994, 14.3k in 2000, peaked at 16.4k in 2005 and now currently at 15.9k...and subsequently has shown no signs of improvement since. You remove the bronco's outlier and their average sits at a little over 14k. Virtually no growth in 20 years....
now...all would not be lost if you take into account total attendances, if you expand your league then naturally you will see averages drop...but....total attendance should increase...as the a-league has proved...however the nrl's total attendance in 2007 was 3,024,040 for a 16 team league....in 2014 it is 3,053,743....
