That's not how I read it. It reads to me like you get one tackle in opposition territory after a try, which allows you to add 4 pointys rather than the 2 you would get from the kick. Similar to the 2 point conversion in NFL.

Hmmm, could be that I suppose. Sounds even sillier to me

It's not very clear at all is it, if it's one last tackle with no kicks from a drop out or restart then I think I would take the two everytime unless you were 7 or 8 behind obviously.

If you scored from that extra tackle, would you get the option again next time?

The main reasons the aussies want 4 refs (and 2 video refs) is to lengthen the game, freeing up commercial time opportunities for the sponsors to try and sell their wares.

One of the obvious problems for me:

If they are trying to get away from kicking goals, but all they will achieve is another form of kick with either: Bomb/ Grubber / Chip.

The defence will be clued up, they will have a set line, so you shouldn't let a try in. Which I think will end up with a big boot to the in-goal area.

Pat Richards would be pleased mind.

but what about the added incentive that if you dont score from the "double-try" the other team gets the play the ball on there 20 instead of kicking off.

Another problem though is, what if the opposition team intercept the ball and run down the pitch and score at the other end, will it count?

Now why didn't I think of that, on page 1......

It just screams NFL

It's no more of a problem than wondering what happens if a conversion kick bounces off a crossbar or post or misses and doesn't go dead.

NCAA and highschool really. The NFL resisted the two point conversion for a long time after the other ruling bodies used it.

I suppose not, but at least in that sitiuation you just rule the ball dead after the kick. Seems a bit less annoying than a situation where the ball is in play for a theoretically indefinite amount of time. I suppose if your try just put you in front with a minute on the clock, it's a good way to run the clock down.

Or you could make it un-timed.
For a while, I have felt the clock should stop after a try is scored and not resume until the next kick off is taken, anyway.
