britexpat,
Well actually the game (at least the AFL competition) has become a lot more sanitised in the past 10-15 years, which many of the game's longer time fans have not enjoyed. All in brawls, like was common 20-30 years ago, hardly happen these days. But the three most common rules are tackling only between the knees and shoulders, tackling only when someone has the ball, and no pushing in the back.

Thanks TheMuss for the info on the rugby club. I have only been in Doha for a week and wouldn't even know where it is (have heard of it though).
