Is this a "Crocodile Dundee" joke?

I want everyone to note that usually when Management-Issues.com speaks I am happy to listen. However on this occasion even though it is NOT April 1st I do worry about the fact that the organisation which undertook the research is called "Hogan Assessment Systems"

Of course I suppose not everyone who has seen Crocodile Dundee knows that Paul Hogan is the real person that personified this Australian larrikin.

From Management-issues.com the following

"As if to confirm popular stereotypes, a new study comparing Australian CEOs with their counterparts in the U.S. has found that the Americans are more conservative and buttoned down, while the Australians are more fun-loving and risk-taking.

The findings are based on results of three personality assessments administered by U.S.-based Hogan Assessment Systems (HAS) to 55 Australian CEOs running organisations with annual revenues ranging from $2 million to $450 million and employing between 10 and 8,500 employees. Almost a quarter of these were women."
