So im hoping to plan an underage party on the goldcoast but am not 100% sure of everything ill need to organise. this is what i have thought of so far. -venue(friend owns an abandoned warehouse.Said he would let me use it for $400. Easily hold 500.i was hoping of cleaning out everything seeing as though its really really grubby such as syringes and shit. but not sure whether i would need any licences or something like that to be able to hold a big party there) -secruity -gear hire (already have a bit of my own gear such as small light rig of about 5 lights, 12 inch speakers.) -advertising -Portaloos - Drinks (red bull,coke and water seeing as though underage.) - having everyone sign wavers saying that any harm caused to themselves is their own fault Could anyone maybe give me an estimated cost of this. And tell me any troubles i could encounter
