The upgrades will help air services continue servicing remote areas

A major $5.4 million federal government initiative to upgrade regional airstrips in Australia is planned for April 2012 to handle growing passenger numbers.

According to the Bureau of infrastructure, Transport and Regional Economics (BITRE) in 2012 22.5 million passengers travelled through regional airports, an increase from 16.8 million five years ago, ninemsn reported.

Figures reveal the average annual growth rate for passenger movement at regional airports surpasses that for major city airports, over the five years to 2010, with the growth rate being 6.1 percent, against 5.7 percent in major cities.

Transport Minister Anthony Albanese said the figures indicate the future for regional aviation and airline businesses looks very optimistic.

"The industry has consistently shown it can adapt to the growing reliance of Australians on aviation both for business and leisure as well as continuing its important role in delivering vital services to regional communities," Mr Albanese said.

Mr Albanese announced the government will upgrade 31 airstrips in remote areas in Queensland, South Australia, Western Australia, NSW, Tasmania and the Northern Territory.
