This is on behalf of my daughter. My daughter, her boyfriend, my son & their friend are leaving for Australia on May 6th. My daughter & her boyfriend will be staying near Brisbane for a month. My son & their friend will be staying for 2 weeks. If you know Brisbane, is there anything I can tell them i.e. places to visit, places to skip, anything interesting, customs, etc. All 4 people were born & raised near New York City & all 4 of them are in their mid - late 20's. They are all college educated (if that helps). Obviously as a mother, I'm concerned about them renting a car since they are not used to driving on the left. Also they want to dive in the Great Barrier Reef. Nobody is certied to dive.
So anything I can tell them I would appreciate. My daughter will be taking her laptop & cell phone. She will communicate with me by email & maybe skype.
