In response to ashley:
The literacy rate for Australia is 100%. Literacy, however, is really a continuum from illiterate through low literacy to high literacy.
The International Adult literacy survey (1998) of OECD countries concluded that 44.8% of Australian adults had a low level of literacy. In this study, a low level of literacy represents a skill level lower than that required for successful completion of secondary education.
These people may have difficulty comparing data, understanding data which is not clearly laid out and following complex instructions. Low literacy can affect the training and employment options available to the person, their financial status and their ability to access services such as health and welfare assistance.
