Keeping in mind that this is a survey funded by Australia’s registry, the data points pretty clearly toward a preference for .au over .com.
From the announcement:
The report found .au remains Australia’s home on the Internet with more than double the level of trust over any other namespace.
George Pongas, General Manager of Naming Services at AusRegistry, said the results show the .au brand position is built on a foundation of trust, reliability and security.
“Two-thirds of survey respondents are more likely to trust a .au website compared with only one-third for a .com,” Mr Pongas said.
The preference for a country code over .com is not unique to Australia. Canadians love. ca. And Germans love .de.
Americans, however, are content with .com.
