Think you know your football? Fancy you know more about the game than your mates, or your work colleagues?

Now here's the annual chance to prove whether your confidence is justified (or embarrassingly misplaced), by entering the 2008 NAB AFL Tipping competition. This year you won't just win bragging rights either – you'll also have a shot at a first prize of $20,000!

Footy tipping is a key part of the season for footy fans everywhere – diehards and casuals alike. It's part and parcel of the footy year in offices, clubs, schools and even within families across Australia.

And there's no better tipping game to play than NAB AFL Tipping. For a start it's easy to play – you just enter your tips each week online at http://afl.footytips.com.au and you can even get the results sent to your mobile if you want. Secondly, you not only get to play against your friends, but you can also pit your scores against those of celebrity tipsters including Andrew Gaze, Garry Lyon, Nathan Buckley, Geelong's Joel Selwood, Jason McCartney, 'Dipper', cycling stars Anna and Kerrie Meares and athletics legend Raelene Boyle.

Then, of course, there's the amazing prize list – starting with a $20,000 NAB iSaver account for the overall winner. Second place wins a Sony PlayStation®3 with a RRP of $699.95. Third to tenth ranked tipsters will receive a Sony PlayStation®Portable worth $279.95.

Every round, the highest ranking tipster will win $1000, thanks to NAB credit cards. And there will be monthly prizes throughout the season, with randomly drawn entrants in various categories winning $1000, again from NAB credit cards.
