It is rumoured that the team is about to have all their players that are likely to be in the goal square have their arms removed and replaced by the these prosthesis. It is envisioned that whenever a corner is awarded to the opposing team, the defenders will remove their arms and place them in the containers situated near the side line.
Each of the arms will be micro chipped to ensure fast and accurate refitting. This way a penalty would never be awarded against them.
The other alternative is to use the prosthesis, but to swap the arms around between the players, that way the players can always claim the arm the obstructed was not theirs.
This is not the preferred method as some players believe that referees would no doubt still blame the wrong player. They believe that it is only a matter of time before a player on the bench is sent off.
The Australians believe that it has proved impossible to improve the limited eye site of referees, so instead this will give the Australians the upper hand.
