Some people that travel to Australia may not necessarily have a detailed itinerary mapped out before they get there. Their flights to and from their home country and Australia may be the only aspect of the holiday that has been booked, thus far.
These people may be more adventurous and would prefer to make their itinerary up as they go along. If you base yourself in Sydney, the largest city in the country, this option is far more amenable to you.
Kingsford Smith International Airport is the best in Australia for domestic flight connections. Whether it is a magical trip to Hobart or booking Melbourne to Sydney flights the whole of Australia really is your oyster. There are a number of airlines that offer flights to other major cities within the country and on occasions, you may actually be able to find a very competitive fare.
You may even choose to travel on to the other side of this island continent: there are regular flights to Perth, in Western Australia and even ones to Darwin, up on the north coast.
Brisbane, Adelaide and Cairns are a few more examples of very popular domestic flight choices from Sydney airport.
If you are feeling even more adventurous, why not take the flight across to Auckland, in New Zealand and make the most of two very different countries whilst you are in the Antipodes?
