Team Fortress 2: Sniper, the resident Aussie, is called Mundy/Mundee, and one of his battle cries with his melee weapon out is a paraphrase of the famous quote:
Freshy Kanal: In response to Bear Grylls' last verse and right before his own, Steve Irwin channels Crocodile Dundee and tells Grylls, "That's a verse? No, this is a verse".
"Bart vs. Australia" naturally has plenty of references to the film, most noticeably a random man who approaches Bart and Lisa in a bar whilst pulling the "THIS is a knife!" routine with a spoon (which Bart immediately calls him out on).
"Boy-Scoutz-in-Da-Hood" has a similar scene when Moleman pulls out an actual machete on Moe...and then falls over due to it being heavier than he is.
Another episode has the background marquee of a porno theater having films like Crocodile Done Me and Dr. Strangepants.
