Sanzar plans to introduce a cricket-style decision review system from 2016 following a number of poor refereeing decisions.

According to The Australian, each team will be allowed as many as three referrals but, as with other sports, will not use up one of their appeals if their challenge is successful.

However, there is still uncertainty regarding who makes the appeal. As the captain may be unsighted or a long way away from an incident, the coach, who will have access to TV footage, could decide whether to review an incident.

Wallabies coach Ewen McKenzie is in favour of the move but warned about the potential for constant interruptions.

'I'm mindful of how much dead time there is in a game,' he told The Australian. 'If you challenge the call and get it right you can challenge again and theoretically you could have 20 challenges.

'People want to be entertained, they want to be kept entertained, they don't want to be sitting there watching replays. I don't know the solution but it is interesting they at least are having the conversation.'

RECENT REFEREE BLUNDERS

• South African referee Craig Joubert said he should not have penalised Richie McCaw at the end of the Super Rugby final, which allowed Bernard Foley to snatch victory for the Waratahs.
• Another South African, Jaco Peyper, told All Blacks coach Steve Hansen that he should not have given Wyatt Crockett a yellow card during the opening Rugby Championship match in Sydney, as the ball was out of the ruck, and was also wrong regarding several free kicks.
• In Napier, Frenchmen Pascal Gauzère failed to spot Horacio Agulla's early tackle on Julian Savea when the winger was looking to regather a chip kick from Beauden Barrett. If Savea had not been interfered with the All Blacks would almost certainly have scored, so a penalty and a yellow card was warranted. Then, with 20 minutes to go, Leonardo Senatore charged down a Ma'a Nonu kick and raced away to score, but the referee bizarrely ruled that the No 8 had knocked on.
• Irishman George Clancy penalised Duane Vermeulen in Perth for a legal hit on James Slipper that cost the Boks three points. Then, with the Boks leading 23-14 after 65 minutes, Clancy yellow-carded Bryan Habana for a high tackle on Adam Ashley-Cooper even though replays, which the referee watched on the big screen, showed that it had not been dangerous.
