Well a reader at LifeHacker knocked out the search plugin for Firefox. I took that and tweaked it for the Australian search engine for those times you need sumthin a little more local. So download it and stick it in your Firefox profile searchplugins folder. Then change the search engine in the search bar to be ‘Google by keyboard (AU)’.

Remember it doesn’t search in au domain by default, it just means the search results will have the ‘pages from Australia’ radio button under the Google search box.
