Bookings for tickets to season 2 are now open at this website. The show will again be filmed at Cockatoo Island on December 5 to 10, but with an option not to camp overnight, a change from last year when every audience member had to stay the night at the island. Also for this year, tickets for overnight camp can only be booked in pairs or multiples of 2.
Edit: according to Cockatoo Island website, filming takes place from 4 to 20 December with 12 evenings across 16 days.
