So I know it's a little corny, but I can hear this or a similar version being sung in a stadium or live site during a Matildas game. Waltzing Matilda was a popular crowd song in the 90s and maybe Sydney 2000. This is intended to be sung to the tune of Waltzing Matilda. Its by no means perfect, so any suggestions to fix lines, add verses etc, please comment! Go Matildas!

Once a team of Aussie girls,
Pulled on the green and gold,
And marched, one by one, behind captain Sammy.
And they played for each other,
While Australia cheered them on,
Come on and cheer the Matildas with me. 

Come on Matildas, Let’s go Matildas,
Come on and cheer the Matildas with me.
And they played for each other,
While Australia cheered them on,
Come on and cheer the Matildas with me.

Foord, Raso, Carpenter,
Hunt, Gorry, Sammy Kerr,
Kennedy, Fowler, Cooney-Cross, Steph Catley. 
Our golden girls are here,
To take on the world for us,
Come on and cheer the Matildas with me.

Come on Matildas, Let’s go Matildas,
Come on and cheer the Matildas with me.
Our golden girls are here,
To take on the world with us,
Come on and cheer the Matildas with me.

Dressed all in purple,
Standing strong between the posts,
Lunging, diving, saving shots on goal with ease,
From the corner or outside the box,
Even from the penalty spot,
You’ll never get the ball past Mackenzie.

Come on Matildas, Let’s go Matildas,
Come on and cheer the Matildas with me.
From the corner, or outside the box,
even from the penalty spot,
You’ll never get the ball past Mackenzie.

Six to six, penalty shots,
Seven million held their breath,
Up to the penalty spot stepped Cortnee.
Calm and poised, straight and true,
Cortnee scores the winning goal,
Come on Australia, cheer for Matildas history!

Come on Matildas, Let’s go Matildas,
Come on and cheer the Matildas with me.
Calm and poised, straight and true,
Cortnee scores the winning goal,
Come on Australia, cheer for Matildas history!
