Elvis and Priscilla entered the Graceland Hotel in Brisbane. After enquiring as to the availability of a room they paid cash for the penthouse suite for three nights. They had not been to Brisbane previously and did not receive any other information about the conditions of their stay at the time. That night, Priscilla's diamond necklace was stolen from their room. The next morning Elvis received a notice from the Hotel excluding all liability for lost or stolen items. Can the notice legally exclude the Hotel from liability in this situation?
