coming from an AFL state and having no choice as a kid, the banana kick was a common part of the game.
obviously you'll need to go out in the paddock on your own for a few hours to get the 'feel' of it, however a few pointers:
hold the ball directly in front of you with the pointy ends in each hand. the pointy ends will be what you aim with. if your taget is on your left, line up the pointy part of the ball with your target and kick the ball towards the right hand point end. use the reverse if your kicking to a target on the right hand side. line up the right hand pointy end with your target, kick the left side of the ball.
