".au.com domains" such as the one you have indicated are not second level or country domains. They are in fact sub-domains of a gTLD domain ie. au.com
au.com is licensed by an Australian company but as far as I know it is impossible for them to guarantee that "registrants" of the sub-domains will always be able to use their .au.com nane as someone, someday may establish a better right to use the au.com domain and may choose to discontinue any service provided to the users of .au.com sub-domains.
