They look so similar some of their Canberra United teammates still get confused at training every week.
But identical twins Ashleigh and Nicole Sykes plan to use their sibling connection to their advantage and leave the Brisbane Roar baffled in the W-League grand final.
And the Dubbo twins are keen to ride a wave of support from a convoy of almost 40 family and friends who will travel to McKellar Park to watch United's bid for an inaugural title.
For as long as they can remember, striker Ashleigh and defender Nicole have used their similar looks to create havoc on and off the field.
After years of being mixed up, Ashleigh even decided to cut her hair for a change and to help people tell her apart from Nicole.
When they were in high school they would regularly swap classes to see if their teachers would notice.
''One day we even swapped test papers for fun and I was really excited when I got mine back and I got a really good mark,'' Ashleigh said.
''Then I realised Nic had done my test ... she's always been the smarter one, a bit more scholarly.
''But I'm older by a couple of minutes, I just tell her to listen to me because I'm older and more experienced.''
Off the field they're the best of friends. They live together, work together at the Lyneham post office and spend most of their spare time relaxing together.
But all sister allegiances are forgotten when they run on to the field for training or a game.
If one of the Sykes sisters makes a mistake during the game, the other is the first to point it out.
But the increased scrutiny and pressure they put on each other is driven by their desire to excel at the highest level.
In fact, their clashes at United training this season have been so intense Canberra coach Jitka Klimkova rarely pits them against each other during drills.
''It got ultra competitive one day, there were a few kicks flying around ... nothing too dangerous,'' Ashleigh said.
''But Nicole didn't like the way I was going and thought it was too rough and she told me straight away.''
Nicole added: ''You never want to lose to your sister, you never want her to have bragging rights. Defending against her is harder than what I play against anyone else and the team finds that funny.''
The Sykes sisters have become a permanent fixture of the United line-up after moving to Canberra for the first W-League season in 2008.
They quickly transformed from lightning quick teenagers from the country and burst into Matildas coach Tom Sermanni's international training squad.
After a couple of seasons off the Matildas' radar, their combination on United's left side has helped them rocket back into contention for more representative soccer.
With Nicole already established as a left defender, Klimkova decided to move Ashleigh to the left side of United's attack this season.
Their parents, brother and sister will drive from Dubbo to watch the season decider.
Cousins will travel from interstate, their ex-training teammates from the Dubbo Bulls are organising to be cheering from the crowd and they hope their grandmother will make the trip down from the central coast.
But Nicole says the most special part of the grand final is being able to share it with her sister.
''We've been lucky enough to play on the same side this year and we've been connecting a lot better than we have in the past,'' Nicole said.
''It's an added bonus having Ashleigh there and it's that there's someone there you can share it with for the rest of your life.''
