Broad opened up about his infamous edge in the first Test for which he didn't walk, admitting for the first time what everyone already knew - that he whacked the ball.
Umpire Aleem Dar's call to give him not out and Broad's decision to stand his ground turned the Test match in England's favour, with the final margin just 14 runs.
Broad said his ears were burning on the field as he went on to make 65 in a match-defining 138-run stand with Ian Bell.
But Broad went one step further and claimed the Australians haven't handled defeat well throughout the series.
"When you play against any side in the world they want their side to win so they are never complimentary. But the Aussies have not taken too well to being beaten," Broad said at an England sponsors' function.
"It is all good fun.
"I can't repeat (what Australians said after the edge to slip), it's not polite.
"I thrive off that sort of thing. It is only sport and a bit of banter.
"You don't want the Aussies loving you because it probably means you are rubbish."
Broad acknowledges that he nicked the ball, but says the edge wasn't as clear-cut as what the media has made out.
He said the bowler Ashton Agar had to ask him if there was an edge.
Broad said it was "embarrassing" that he'd copped so much abuse for not walking when several players from both sides have done the same thing throughout the series.
"It was an odd one. There was no particular noise. It was noise off (Australian wicketkeeper Brad) Haddin's gloves. It is silly when people say it was nicked to slip because it was en edge to the keeper's gloves that flew to slip," he said.
"The whole walking debacle I thought was pretty poor journalism because it was just one player who was picked up.
"I have named seven or eight Australians and four Englishmen where that has not happened."
Broad described England's surge to be 3-0 up in the series as "unEnglish" and promised the steel mentality shown to win the big moments would continue in the return Ashes down under.
"One thing about this England team is we are tough," he said.
"We come through tricky times and we stand up and want to be counted.
"It is quite an unEnglish thing that this team has got.
"We want that to continue.
"Fans like winning teams. We are proud of that. We do have a win at all costs mentality."
