I just booked my trip down under! I went on http://www.australiaagogo.com and not only did I book my flight and hotel but this site had a lot of information for different activities and tours and you can book them along with your flights! Definitely an informative website, if you plan on traveling to Australia, I would do it through this website!:D
Really, do they give you full details for hotels? Can we ask them to look for hotels in Sydney? How about their rates? I guess have to check first their reviews before trying their service.Thanks for the effort mate.
