Giant brake thrives naturally in a stretch of major regions, spanning from Asia and Oceania to the African continent. It has also established a presence in portions of Central and South America, essentially in tropical and subtropical zones. While giant brake has been introduced to several countries within the Americas, it is sometimes thought to be gently expanding its ecological footprint. In areas where it's considered invasive, like certain island ecosystems, giant brake may have an impact on native plant communities, although its overall effect is currently subtle compared to more aggressive species.
