They have lampooned other countries as well though. Americans are gluttonous and greedy. South Africans are angry with everyone. Japanese and Koreans lust after everything.
The magazine attached values to things we do, for example, plastic surgery (pride), violent crime (wrath), theft (envy), holidays (sloth), food (gluttony), salary (greed) and porn (lust).
Australians are busy little creatures. Apparently we do all of these. Think what everyone else is missing out on! We always thought the Brits were envious of us. Now we know why. Start a barbecue, open the beer, and Aussies will be there. Of course we like to indulge. That is what life is about.
