Since his appointment, Stajcic's intent has been for the Matildas to develop an exciting, attacking style of football, chossing a squad he said is capable of competing on the biggest stage in women's football.
"We have selected a positive squad with players that have a strong belief that they can go into any game and win," Stajcic said.
"Over the course of the last four months the composition of this final squad has changed every week, but as always I believe 'players pick themselves' and the 23 players that have been selected thoroughly deserve to be in this squad and I am confident they will represent their country with distinction.
"The emphasis since we came together in January has been on expressing our Australian culture and the things this country is renowned to bring to any sporting contest, things like positivity, backing yourself and really taking it up to the opposition.
"We want to pride ourselves on a lot of these attributes that Australian teams have had for a long time, so it is about having that focus in this team and a belief that on any given day against any opponent we can come out and win.
"Considering the other teams we have in our group, it brings this philosophy into even sharper focus."
With the likes of reigning Asian Female Player of the Year Katrina Gorry and Julie Dolan Medal-winner Emily van Egmond, among a host of others, in the squad, Stajcic believes he has a unit capable of progressing from a tough group that includes world number two-ranked United States and fifth-ranked Sweden, along with 2014 African Women's Champion Nigeria.
"Going on from our philosophy and style of play, it's a dynamic, mobile team that can attack and score goals," Stajcic said.
"It is a team that has lots of variations in attack so I believe we can cause a threat to any team in the world, and the players that were picked were certainly picked with that in mind.
"Whether it's keeping possession and playing out from the back and controlling the tempo, to the fire power we have up front, we are confident we have all of the pieces of the jigsaw puzzle that go into producing the mindset we need when we take the pitch."
Australia had the second youngest squad at the last Women's World Cup in Germany four years ago, and will go into the 2015 tournament with a blend of youth and experience.
Having last represented the Westfield Matildas in 2012, Hudson (nee Barbieri) will head into her fourth World Cup at the age of 35, while Queensland forward Larissa Crummer is the youngest member of the squad at 19 years of age.
Hudson is one of the three goalkeepers alongside Lydia Williams and Perth based Mackenzie Arnold, who was named W-League 2015 Goalkeeper of the Year.
Tameka Butt, Samantha Kerr, Leena Khamis, Kyah Simon and Williams all made the cut after overcoming injuries, Williams and Khamis having both recovered from their second knee reconstructions.
Although Perth Glory striker Kate Gill, a veteran of 83 matches for Australia, in which she has scored 40 goals, was a surprise omission.
"We now have our World Cup squad finalised, and now it is left with this group to carry the torch into taking on the world's best," Stajcic said.
"While it is a credit to the girls that have made it, we have achieved nothing yet as a team and there is still a lot of hard work to be done to achieve our potential."
The announcement of the captain will be made at a function hosted by His Excellency General the Honourable Sir Peter Cosgrove AK MC (Retd) Governor-General of the Commonwealth of Australia on Monday 18 May 2015.
