i need help answering this question using Australian consumer law only ACL

The Mile High Travel Agency Pty Ltd in Perth ran a series of advertisements in newspapers and magazines promoting an overseas tour it had organised. The advertisement read as follows: THE GREATEST EXPERIENCE OF YOUR LIFE OR YOUR MONEY BACK!! Yes, exciting action packed, sun-sun-sun filled 14 day fully escorted tour of the West Coast of America with extended stopovers in Honolulu.... and for just $3000 per person!! Anne responded to the advertisement by calling into the agency, but was informed that should she desire, as requested, private accommodation, her fare would be $3500, as the advertised price was based on twin share accommodation. She was also informed that some of the tours may in fact only run for thirteen days. Anne ultimately went on the advertised tour, but was disappointed with it. The weather was generally poor and on four separate days, the tour participants were given 'free' days when they were left to their own devices. The tour was also only twelve days. Advise Anne if she can take action against Mile High Travel Agency and if so, what action she can take.
