Aussies now have a chance to win a $20,000 AUD reward via "The Edge of the Internet" internet treasure hunt launched by Microsoft Australia. The new contest aims to promote Internet Explorer 9 through the browser's advantageous rendering speed than any artificial benefit.
When you register for the journey to the Edge of the Internet you'll be given a bunch of links to other web pages - one of which was the last place Dave was seen before he got lost.
"Your challenge is to make your way to Dave - click by click and page by page. Follow the wrong path and you could be clicking 'til the end of time. Follow the right path and you could be first to reach Dave and score $20,000. With so many web pages out there, you're going to need a really fast browser - and Dave's number-one recommendation is Windows Internet Explorer 9."
Although there is no end date, the competition's terms and conditions reveals there are "seven Hunt Pages that are a path to the final page".
The competition is only open to Australian residents and you can register here.
The first hint of the puzzle revealed today is an dated music video on YouTube with the comment, "Why do I have this song in my head???":
