olols, funny you mention this cos im playing in an oztag comp tomorrow...
Anyways, from what I've gathered:
-you can only kick on 0, 4th and 5th, and all kicks have to be below the refs shoulders
-There's no actual ingoal, just a tryline, so if you kick, you have to regather before it goes over the tryline, otherwise it's out
-Instead of stepping like you would in league/touch, try to swerve your hip from side to side so that the tags swing all over the place, or spin around past the defense
-Tag with both hands. That way if you miss with one, you'll get it with the other
-Not sure if this applies for Tag as well, but in Touch footy, if the ball touches the floor (ie knock back), it's a handover
-Put your fastest blokes in the middle so that they're around the play the most. Tall blokes on the wings
-Take dummy half runs and try to involve the person who just played the ball if it's a quick PTB, that way you take advantage of gaps in the centre of the field
-If you fall over and someone is within tagging distance, you're automatically held
-If you think you've been tagged, keep running, cause chances are the tag only came half off
-Stick your tags facing upwards, that way they're shorter
