Hi Blake, we looked up the rules of this variation of tag/touch for you you and found this succinct explanation on Wikipedia:

OzTag is a non-contact form of rugby league. OzTag is a variation of British tag rugby. St George Dragons halfback Perry Haddock, introduced the sport in Australia while coaching the 1992 St George Jersey Flegg side. Together with Chris Parkes, the two took the sport to fields across Australia. Today, it is played by over 100,000 players in organised leagues across the country.

For the full set of rules of Oztag see the Oztag Rulebook (pdf): http://www.oztag.com.au/sites/oztag/files/files/Oztag-Rule_Book_2013.pdf

Games are usually played over 20 minutes a half. The normal dimensions of the field are 70 metres x 50 metres. Eight players in each team are allowed on the field at a time.

The attacking team has six plays or tags to try and score a try or take the ball down field as close to the line as possible. Like most versions of tag rugby, a tackle is made when one of two velcro stripes, known as tags, is removed from the ball carrier's shorts.

Players can pass and kick the ball and tries are worth one point and there are no conversions. Kicking in general play is allowed but it must: be below shoulder height of the referee and on zero count with no play-the-ball (from playing a knock-on advantage for instance) or after the 4th tag.
