When Matt Giteau missed a last minute conversion three years ago at Murryfield to give Scotland an unexpected victory over the Wallabies 9-8, the result caused ramifications in Australian rugby and the back door for Giteau.
Last year leading up to the RWC Wallabies coach Robbie Deans picked a young side to tackle an unknown Samoan side in Sydney for their first outing for the season and again Deans was embarrassed when the brave Samoans defeated the Wallabies without too much trouble.
And again in 2012 Deans had to face the humiliation of watching the Wallabies lose their first of 15 Tests in 2012 to a young and hugely committed Scottish side who failed to win one of their Six Nations internationals last season.
After last years failures Deans is now under more pressure than ever and no matter what excuses he serves up to the Australian media the fans will be baying for his blood.
Scotland are currently ranked twelfth on the IRB ranking and the fanciful Wallabies second but reputations mean nothing if teams like Australia cannot deliver results with any consistency.
The Wallabies can cry as much as they like about the lack of time to assemble their team because of Super Rugby and that the match was played in almost cyclonic conditions but what they fail to realize it that the brave Scots are in the same position resting some of their seasoned players in order to give the youngsters a go.
In the first half playing into a gale with rain constantly in their faces they Wallabies stupidly elected to put up the high ball only to watch it sail back over their heads which makes one wonder if they had any brains at all.
After a brief period when the Wallabies dominated early possession the Scots used the wind to their advantage and spent most of the first half in Australian territory and they were rewarded with two first half penalties to No.10 Creig Laidlaw.
As you would expect in such trying conditions both sides played the game close to their forwards and this was a match where the three-quarters just made up the numbers with relentless pick and drives from the pigs.
Trailing 6-3 going into the second the Wallabies running with the wind at their backs quickly drew level when Mike Harris kicked his second penalty for the day to even the score 6-6 after 42 minutes.
One would have thought that the Wallabies would have started to take control of the match and again it was nine man rugby from the Wallabies with half back Will Genia looking for his forwards to punch it down the middle.
There were plenty of opportunities for Genia to send his pass wider to his possession starved backs but no he elected to play wet rugby to the hilt to the extent that most of the Wallabies backs joined the pick and drive machine if only to keep warm but unfortunately to no avail.
In the second half the only time Scotland crossed the half way and into Australian territory was with five minutes of play left in the game with the score locked at six all.
The Scots maintained control of the slippery football gradually working their way to within striking distance and their efforts were rewarded when referee Jacob Peyper awarded a penalty to Scotland after the Wallabies scrum collapsed.
Laidlaw kicked the winning goal in extra time to give Scotland a deserving victory in Newcastle 9-6 to send shivers through out Australian rugby for the third time in as many years.
For Australian rugby supporters it was a wet and miserable evening with most supporters getting hypothermia watching the Wallabies make a mess of it all over again.
It will be interesting to see what Deans does before the weekend when the Wallabies face Wales, the Six Nations champions in Brisbane because another loss will quickly set the anti Deans faction into over drive.
It was a disappointing effort from the Wallabies and it would be a waste of time to offer any excuses for their insipid performance.
But Scotland should be proud of defeating Australia at home and away which will give them confidence when they travel to Fiji and Samoa later this week.
Rugby is a funny game if you have a sense of humour but in Australia we haven't had much to laugh about for years now and we are beginning to become very depressed and unsettled about our rugby which in my opinion continues to struggle.
