"He just backs me with what I do and gives me that licence to play what I see," Munster said of Bennett.
"That is what you want from a coach – I'm only six foot two but it feels like I am seven foot out there at times getting coached by him."
After winning Origin I in Adelaide last week, the Maroons can clinch their first Origin title since 2017 at ANZ Stadium tonight.
On Sunday, Munster slammed "disrespectful" reporting in the media that Queensland had the worst Maroons side in history.
"I don't really read too much in the media, but I guess that's not a great accolade to have ... it's a bit of disrespect from them," Munster told reporters on Sunday.
"We're in the same position we were in last year, where we won the first game and lost the last two.
"All we can do now is make our performance talk – they can talk as much as they want in the media, but for us to get a bit more back is to play well on Wednesday night.
"We've got no pressure on us, everyone is really doubting us and we're the underdogs."
Origin II kicks off at 10.10pm New Zealand time and the New South Wales Blues need a victory to keep the three-match series alive
