Perhaps therein lies the problem. Melbourne is a good example, if that is the case. Rod Laver Arena, our main arena, holds about 13,000 people for a standard concert. The only other venue used for concerts of this magnitude now is Telstra Dome (formerly Colonial Stadium), which has a capacity of 55,000-60,000! There isn't any in-between venue, except the place they used the last time they were here for a real tour, Olympic Park, a soccer (football! :P ) ground that could hold around 30,000 for a concert, though that is an estimate. However, I haven't heard of anyone using that for a gig for a while now.....
