The England pace bowler James Anderson has revealed Australia refused to share a drink with the home side following their opening Ashes win at Cardiff.
England won the first Test by 169 runs, with more than a day to spare, to go 1-0 up in the five-match series heading into Thursday's second Test at Lord's.
Anderson said England and New Zealand had shared drinks, regardless of results, following both matches in their drawn 1-1 Test series in England earlier this season.
England captain Alastair Cook invited Australia counterpart Michael Clarke and his side into the home dressing room after England's emphatic fourth day win but was rebuffed.
Anderson, England's record Test wicket-taker, was at a loss to explain why.
"That's their (the Australians) prerogative," he said. "After the New Zealand series, we had a beer after each game with them."
"We found that was quite an enjoyable thing, just to chew the fat after a hard Test. It didn't matter whether we won or lost."
"At Headingley (where England lost to end the series all square at 1-1), we still went into their dressing room and had a beer with them"
"It's Cooky's idea. He's the captain, he went and asked them. We were all happy to do it. I don't know why they (the Australians) didn't come in."
Having a drink with your opponents after the end of a match has been a part of all levels of cricket, and especially Australian cricket, for generations.
Indeed during the 2005 Ashes series, widely regarded as one of cricket's greatest contests, the teams split a beer after each match.
However, then Australia captain Ricky Ponting said afterwards that what he felt was an excessively friendly atmosphere contributed to his side's defeat.
In recent years in Test cricket, the practice has been for teams to share a drink at the end of a series but not during.
Before the present series started, there was much talk about whether 'sledging' or verbal abuse of opposition players would be as much a feature as it was in Australia's 5-0 home rout of England during the last Ashes campaign in 2013/14.
