According to the smh.coom.au website, But enough's enough - Hansen wants the booing to stop.
Wallabies playmaker Cooper has been the subject of vitriol from New Zealand crowds for the past two years, most recently in last Saturday's first Bledisloe Cup Test in Sydney.
After replacing five-eighth Matt Toomua for the final quarter, Cooper was greeted with derision on every touch from the Kiwi contingent in the crowd.
His arch villain status began when he kneed All Blacks skipper Richie McCaw in a 2011 Test, and was amplified during that year's World Cup.
McCaw fanned the flames in his autobiography last year, saying "players like Quade get sorted. Sooner or later they get their beans".
Hansen says the second Test in Wellington on Saturday, which falls nearly two years to the day after the kneeing incident, should mark a turning point.
"He's brought it on himself but probably it would be good if we all got over it," Hansen said.
"I don't boo him and I'll continue not to boo him. I think he's a good player, I think he's not a bad bloke either when you have a quiet chat to him."
Hansen echoed the thoughts of Wallabies flank Michael
Hooper, who said the booing during Australia's 47-29 loss on Saturday
was "below the belt".
