Teenage phenomenon Mary Fowler has signed with Adelaide United for the W-League season.
The 16-year-old, having already represented the Matildas four times, was part of this year's Women's World Cup squad in France.
The Reds have also signed Fowler's 18-year-old sister Ciara with the pair to play in the W-League for the first time.
Ciara is a Young Matildas representative who has also represented Ireland at under-19 level due to the pair's Irish father.
United coach Ivan Karlovic said the pair brought vital experience to his squad despite their tender ages.
"Both Mary and Ciara have experience with the national set-ups and this will certainly help us as we head into the new season," Karlovic said.
"It will be a new experience for Mary and Ciara playing in a different state, but I'm confident this adventure will help them continue to develop both on and off the park."
