Cassandra Giudice says promoting transgender awareness and diversity were key messages within her band's music.
However, the songs also address other subject matter.
"There are songs about my journey as a transgender woman, and then there's songs about things that everyone can relate to," Giudice said.
"Things like you've got a job and then the firm goes bankrupt, or you've got a car that breaks down, or you've got a relationship that just doesn't work out and you've got a broken heart.
"It's nice for me as a performer to be able to write and present music that everyday people can relate to in a humourous way."
Sydney-based Giudice, 40, began her gender transition about a decade ago.
She works as a criminal lawyer, and also performs music as Cassy Judy.
Giudice felt "lucky to be able to live my life in a comfortable way" nowadays.
"I'm so lucky as a transgender woman," Giudice told the Mercury.
"I used to live in Broken Hill many years ago... Last year I went back there and performed at the festival, and it's really happening in the regions with the passing of the gay marriage postal vote.
"I think we're in just such a great time for trans people, and people who don't identify in that traditional way that a lot of society's used to - (that) you're either a boy or a girl.
"Things are really shifting, which is really exciting to be a part of."
Primarily working for Legal Aid, Giudice said her own life experiences have perhaps afforded a unique understanding and empathy for people caught up in the legal system who are facing obstacles in their lives.
"It's useful work to help people in their time of need.
"And it can be very rewarding where people can actually make a change in their life, and I can help put them in touch with the programs and services that will help them to do that."
Giudice sings and plays guitar in pop/rock band The Cassy Judy Experience, who will perform in the Illawarra for the first time this week.
They'll be appearing at the Servo Food Truck Bar, Port Kembla on Friday night.
"It's a venue that encourages diverse sorts of acts," Giudice said.
"We're a band that supports diversity and visibility of queer people.
"So it's great to come into a place like Port Kembla which has that industrial history, and go, 'okay, this is who we are and this is what we're about'.
"And we'll do it in a really fun way that gets the crowd involved."
Also performing will be Ghost Gurl and Caitlin DC.
