What do ya reckon...., 50/60,000 tickets?
Hard to know mate.
If the stage is gonna be where the main stage at Oxegen is then it could be anything up to 60,000 I suppose.
With all the other stalls etc not there, it leaves plenty of room on that field for fans.
I'd say it would hold 50-60,000.
As long as I'm one of them, I'll not argue!
