Around 55 percent of appreciation is seen in the number of tourists passaging via Australia's airport since last decade. The reason behind this is the craziness of people for traveling and coming up of cheap transport, which has increased the mobility of people to such an extent.

The number of aircrafts would also have increased simultaneously in order to serve the increased number of tourists, but it didn't happened and much of the rush is seen in the larger planes nowadays. The flight frequency has been increased by some air carriers, but there has not been much done to adjust the rush-however, this has ensured all flights to be jam-packed.

The Bureau of Transport and Regional Economics conducted a survey, which proves that the figure of domestic visitors at almost all Australian airports has gone up by 55 per cent, from 56.2 million in 1997 to 87.3 million the previous year. There has been a tremendous traffic between major Australian cities. 

Within the same duration, the figure of international visitors has gone up by 45 percent, from 14.1million in 1997 to 20.5 million the previous year. Though, the total figure of domestic, regional and international airline flights has gone down from 1.27 million to 1.18 million.

Around 70 per cent of domestic passenger traffic and 95 per cent of international passenger numbers is favoured by the top five Australian airports-Brisbane, Sydney, Melbourne, Perth and Adelaide.
