The performer, who appears in comedies Bridesmaids and Pitch Perfect, told Metro that she already has some projects in the pipeline and is keen to find dual writing-acting roles in future.
When asked what she would like to achieve in her career, Wilson said: "I'd like to write my own material.
"I have a sitcom in development for US TV and I'm developing a movie that I'll write and star in myself. I'd like to do more writing/performing rather than just come in as an actress."
She also revealed that she did not think she would become a professional actress when she was at school, but a life-threatening bout of malaria made her take the leap and enrol in acting school.
"I was very studious and was selected to be a youth ambassador for Australia for a year after high school and went to South Africa, giving speeches about Australia," she said.
"I got malaria and almost died. When I was in the hospital the drugs made me lose my hearing and I started hallucinating for two weeks. All I can remember is this hallucination where I was an actress winning an Oscar at the Academy Awards and, instead of doing an acceptance speech, I did an acceptance rap."
Wilson added: "Everyone thought I was nuts. I'd already got into law school and would have become a lawyer but I followed my gut instinct."
