Avline provides a summary of previously released Aviation related data drawing on a range of sources including BITRE, ABS, Airservices Australian and the US Energy Information Administration. In addition, Avline provides a comparison of published airport charges at the five major capital city airports and at a selection of regional airports. Avline 2008–09 covers the financial year 2008–09 and is the first of the series to be published annually instead of biannually.
Avline 2008–09 was originally released on 3 June 2010 but was revised after computational errors were identified in Chapter 5–Airport charges. This amended version was released on 9 June 2010.
