The Happiest Nation on Earth

With cute animals like koalas and rockin' economy, it's no wonder that Australia is a happy place. In fact, it has just been ranked as the world's happiest nation three years running by the Organisation for Economic Co-operation and Development (OECD):

Australia has been named the world's happiest industrialized nation for the third year running, based on criteria including satisfaction, work-life balance, income and housing, a survey released Tuesday has found.
The so-called "lucky country" beat Sweden and Canada to take the top spot in the Organisation for Economic Cooperation and Development's (OECD) Better Life Index.
Australia has remained largely immune from the global financial crisis, with its economy growing on average 3.5% over the last 20 years to 2012, according to the CIA Factbook.
