It will be a very basic facility. This is not a facility with beds, it is not designed for the long-term, it is designed to protect people’s physical safety during the most intense part of this cyclone,” Schrinner said.“We have modelled this on the cyclone shelters that are used up north, in northern Queensland, and also the Gold Coast is using a similar approach.”
