Quote: Flashjohns "Its simply one more play worth 4 points, if you score or not play resumes as a re-start as it would after a conversion attempt.
Didnt hear a mention of what happens in an interception scenario and couldnt find anything online, even on the NRL homepage. Id probably say the play is stopped if the defensive team recover the ball, this is based on the NRL Allstars knocking on in their attempt and play stopping but this is just my opinion.'"

I think the line "Any stoppage other than a try will see the match restart with a kick-off from halfway" means a try to the attacking team and that if the attacking team lose possession such as an intercept then the play is over and kick off from half way as per usual.
