Mr Crouch and Ms Kane will take part in the Pontifical Council for the Laity sponsored forum on the theme of "Witnessing Christ in the World of Work", a bishops statement says.
According to the Vatican press office, "participants will look into the relationship between the young and the working world, highlighting the rapid transformations that mark the era of globalisation, the problems and present challenges".
According to the bishops, Mr Crouch and Ms Kane both have extensive experience of life and work and its integration with faith, which will allow them to represent young people authentically.
"It is a real privilege to be representing the reality of young workers in Australia," Ms Kane said. "It is significant that young workers lives are being taken seriously and a forum is being dedicated to this."
Bishop Eugene Hurley, Chairman of the Bishops Commission for Pastoral Life said that both delegates were "typical of robust, involved Catholic young people in Australia".
"I am confident they will represent Australia well and be great ambassadors for the faith on their return," he said.
According to Kath.net the forum will be attended by around 300 people between the ages of 20 and 35, all with a solid background of commitment in the Church and in the world of work.
They come from around 100 different countries and have various work and ecclesiastical experiences. Also participating will be around 30 guests, including speakers and participants in round table discussions.
