Wallabies five-eighth Kurtley Beale was the latest to express his view on Farrell's tackle ahead of Australia's test with Wales in Cardiff on Saturday (Sunday NZ time), calling for consistency with decisions.
Australian referee Angus Gardner came under heavy criticism after he didn't award South Africa a penalty for what looked like a risky and no arms tackle by Farrell on Esterhuizen in the 84th minute of the match.

England kicked it dead but instead of blowing for time, Australian referee Angus Gardner called for a TMO review, with a potential match-winning penalty in easy range for Springbok outhalf Handre Pollard.
South Africa's management were furious at Gardner's failure to act, their coach Rassie Erasmus praising the tackle in an answer laced with sarcasm, but Farrell himself insists there is no case to answer. "As he bounced off Esterhuizen, Farrell tried to dislodge the ball; he was not trying to wrap his arm". Like, I don't understand this, guys. We lost a few games but we played tough today and we won.
