Belinda D'Alessandro was born to an Italian father and an Australian mother in Brisbane, Australia, in the early 1970s. At the age of seven, her father immigrated to Australia from Italy. Her maternal great-grandparents came from Scotland and Ireland, and she has relatives in Italy, New Zealand, the United States, and Canada.
D'Alessandro, the eldest of five children, was raised in Brisbane and the Gold Coast and graduated from Bond University with a law degree in 1992.
For 15 years, D'Alessandro worked in government and the private sector before moving to Sydney in 2000. In addition to writing her debut crime novel, she founded her own boutique publishing company, BDA Books, in 2007 and entered the banking and financial services sector in 2010.
While working full-time in the heart of Sydney, D'Alessandro is currently developing her second and third books, which follow her debut crime novel, in her spare time.
