Last time I was there - 2009 and Darwin, Wilson Crescent, Moil to be exact - our hosts told us that it is now wrong to call the indigenous people 'bloody aboes' and now refer to them as 'them black fellas' so felt that there was an improvement. There thoughts on Muslims was pretty horrific. They had not 'improved' in that department
They were horrified when we went off cycling most days. We had packed our helmets, knowing the Aussie law about them. We encountered no problems with other road users in Darwin, there were quite a lot of people on bikes. We were riding near the University are though, so maybe that is why.
