It is not overstating it to say that it the oval that causes manly the biggest problem from a sponsorship point of view. The biggest shortfall is in the Gold and silver sponsorship areas which are around the 30-50K per year sponsorships and the simple reason is there is no where to put them. The only boxes that cater for that investment are at the southern stand and they are full because there is only 12 of them the boxes around the ArkoStand/Presidents lounge carry the heavyweights Delmege, Strathfield Reed etc. there is no room left on the jumpers and no one is going to invest anywhere near 50K for static signage whether it be on the ground or elsewhere.
The tennis box category is around the 8-15k per annum mark which attracts your small to medium local businesses but even with them there are not that many left but you would have to sell 5 of them to equal 1 of the gold boxes.
The best illustration i can give for it is to see how hard they are pushing to fill the coporate boxes at Gosford because what has happened is they have put everyone who currently has property in brookvale effectively into one side of the stadium up there and have exactly the same available on the other side of the stadium to fill.
