The group is currently based in Redfern, in Sydney's inner city, but with plans to expand to Parramatta in Sydney's west - a multicultural heartland.
"There's so many young people. They don't get the opportunities other people have," the group's Director Cath Keenan told SBS World News.
"They have lots and lots of new arrivals, lots of refugees obviously.
"There's also the largest single indigenous population in the country, and we really want to work with these kids."
The group runs free programs aimed at sparking interest in writing, improving skills and boosting confidence.
"We work with a lot of kids that have low literacy levels, that are disengaged from school, that don't feel that writing is something that they're good at," Ms Keenan said.
"So what we're really trying to do is show that writing can be really fun, and really empowering, and send them back to school with that motivation and enthusiasm to learn and flourish."
The group was founded five years ago, and now has more than 11,000 students.

It's running an auction to try and raise the funds needed for the expansion towards Parramatta, with about 50 artists, including four Archibald Prize winners, donating pieces.
Last year's Archibald finalist Abdul Abdullah is among the donors.
"Often I'm looking at the experience of marginalised people, and in Australia I look specifically at the experience and contemporary experience of young Muslims, and how we're perceived," he told SBS World News.
"And how our actions and beliefs, our actual actions and beliefs are so often irrelevant to how we're perceived from the outside.
"I find myself relating more to these marginalised kids than any other kids, so that gives something for me to really appreciate giving something back to them."
The exhibition and online auction ends on Saturday.
