Earlier, Slater was also heckled by the fans at ANZ stadium when he appeared on the big screen preparing for the game in the dressing rooms, which provoked a similar response on social media.
After the game, Slater was philosophical about his career and gracious in defeat.
"It's now how it's panned out, that's footy," Slater said.
"We tried our best but that's the way it goes. I'm really grateful for the career I've had, the friends I've made and what rugby league has done for me.
"It taught me lots of things – selflessness, respect. I appreciate everything everyone has done for me
"We didn't help ourselves. We dropped the ball…we couldn't handle their big guys. That's footy. It's the way it went."
