A teenager who started sexually abusing his little sisters when the youngest was four used their deceased father's greenhouse to commit the crimes.
In a decision published on Thursday, August 6, the ACT Supreme Court handed the man, now 30, an eight-year jail sentence to be suspended after four years and six months.
The abuser, who cannot be named due to his age at the time, previously pleaded guilty to numerous historical charges including incest and committing acts of indecency on a child.
