It would need a unanimous vote to permit access for the owners to permit general public access like this. If this is a cross lease there is unlikely to provision in the cross lease for a majority decision, but you should get a copy of the cross lease to confirm this. If this is a unit title then you would need a body corporate resolution, which could be a majority. So I suggest you confirm what sort of title you have and this will confimr the answer.
There is a third possibility, that this ia a right of way easement, appurtenant to the sections. This would also need a unanimous vote to permit public access.
