hey BW,
first, "it's not a bug, it's a feature" - DDG's stance against personalization and "bubble filtering" means that the search engine tries to be as egalitarian to all its users. See for more on this.

However, if you *really* want to receives websites in a specific language you can use the site: operator. For instance, "car rental" as a partial solution OR you can modify the default settings on by clicking "More" > "Settings" > "Region:Australia" and it should work.

The region settings returns pretty local results for me. If it doesn't maybe you should list an example here as crazedpsyc said.
