Abstract: How to effectively protect linguistic diversity against the background of globalization poses an urgent problem for many countries.Australia is one of the countries with comparatively more endangered languages.Since 1970s, the Australian government has taken various measures to research and protect the endangered languages among which encouraging indigenous language teaching is key, which, to a large degree, has obviously slowed down the process of deterioration of the concerning languages but is still not adequate enough to change their fate of disappearance.Therefore, how to save the endangered languages remains a problem which needs new solutions.
