It turns out that one of the most popular cliches—that money can’t buy happiness—may not be true.

A recent survey conducted for lottery groups in Australia showed that it take AUD$10 million (US$7.7 million) to realize their dream and be happy.

ReachTel, the organization commissioned by lottery groups in Victoria, South Australia, Queensland, and NSW to conduct the survey, found that 30.4 percent of Australians believe that winning at least $10 million in a lottery would be ideal to make their dreams a reality.

Some 24.3 percent of the respondents, on the other hand, are contented with AUS$1 million (US$772,460). The results, according to the survey firm, was in contrast to a similar survey conducted six months ago, which showed that AUS$1 million is enough to fulfill their dreams.
