The Crystal Cube Company Pty Ltd published an advertisement in all the major newspapers claiming that anyone who used their 'crystal cubes' would not develop cancer. If they did, the company would pay them $200,000. The company lodged $200,000 with their bankers as a sign of good faith. Caitlin bought and used the crystal cubes as directed and developed cancer. She claimed $200,000, but the company refused to pay her.

Advise Caitlin on whether she can claim the $200,000 using relevant legal rules and principles. You may also cite a relevant case to support your answer.
