"That's my opinion and I'm entitled to voice my opinion, right or wrong."
Thorn said the All Blacks "culture of respect" was an eye-opener after his years in rugby league.
Thorn, a New Zealand-born Queenslander, played 460 game of first class rugby league and rugby union over a staggering career spanning two decades and including Rugby World Cup, Super Rugby, European Cup, NRL grand final and State of Origin triumphs.
He played 59 tests for the All Blacks including the Rugby World Cup final in 2011, his final test for New Zealand.
"You had to sit in a certain seat on the bus. You had to earn your way to the back seat. On an aeroplane we didn't get off until the public got off.
'It was all respectful stuff and I got used to that, so I think the current All Blacks would definitely respect the Wallabies. It's a Test match between two countries that have been going at it for 100 odd years."
The 41-year-old believes that Cheika's angst over the New Zealand Herald "clown cartoon" on the eve of last weekend's test match was overblown.
"With the media, stuff goes on and you've got to keep that in perspective. It's something that makes State of Origin interesting. There's stuff thrown by either side and it spices things up."
