Yeah okay Ill go with 70k-80k, but I live in WA as well which is why I made the comment re Subi.I dont think you will find many wc or freo supporters who want a granny at subi - its a shithole, however:
You dont need a 100000 seat stadium for a good grand final - 70-80k is fine - very few stadia these days are built at 100k as they tend to be white elephants
Last 4 World cup finals have had attendance as follows - if a stadium that size is good enough for the biggest sporting event in the world .......
International Stadium YokohamaYokohama, Japan69,029[41][42]
2006Italy1–1
[n 8]FranceOlympiastadionBerlin, Germany69,000[43][44]
2010Spain1–0
[n 9]NetherlandsSoccer CityJohannesburg, South Africa84,490[45][46]
2014Germany1–0
[n 10]ArgentinaEstádio do MaracanãRio de Janeiro, Brazil74,738
Around about the time the g's contract finishes, adelaide, sydney, perth and melbs will all have gf class stadia - at that time we should start to rotate it - id say on a one in melb - one interstate, one in melb - one interstate basis
