Australians have two new things to worry about this week.
One is that researchers have found that crocodiles can climb trees. They studied croc behaviour in Africa, North America and Australia and it seems they can climb at least 6 feet, maybe as high as 30, if anecdotal accounts are to be believed.
They may climb very slowly but it may be wise when in crocodile country to look up as well as around.
The other great danger to Australians is the steady creep of the political right out on to a branch that looks like fascism. This may seem startling but there are certain signs that on their own signal a warning but collectively constitute danger.
The first has been the move by the Abbott Government to accuse the publicly-funded ABC of bias in their reporting of events relating to turning back refugee boats. Prime Minister Tony Abbott felt that as the national broadcaster they should be "for Australia not against it". In other words, it should only report what the Government wants it to report and not what is happening. In a country that considers itself a democracy, this threat to a publicly-owned media outlet is a warning.
