She was born male but hearing her story it's clear that she never was a boy.
"I am definitely a girl. That's all I consider myself as," says 12-year-old Jazz, who was born male but began identifying as a girl from a very young age, presenting herself formally to the world in that way from as young as five.
"I have a girl brain and a boy body," she explained when she was just six.
Her supportive parents realised early on that Jazz's desire to identify as a girl was a deep-seated, life-long feeling; and so after their lobbying she's formally enrolled into school as a girl, is named female on her passport and plays with all the things 12-year-old girls love - especially mermaids.
"I believe it's because of the ambiguous genitalia ... there's nothing below the waist but a tail, and how appealing is that for somebody who doesn't like what's down there?" explains her mum Jeanette of Jazz's obsession with all things mermaid.
"I don't really care what they think," her mum adds when asked about the people who just don't 'get' Jazz's lifestyle.
