Transgender woman Evie Amati has begun the process of "de-transitioning" from jail, where she was sentenced to at least 4½ years for a brutal axe attack she inflicted in a convenience store in Sydney’s inner west in 2017.

Evie Amati hits strangers with an axe at a 7-Eleven in Enmore on January 2, 2017.

The 26-year-old revealed she was beginning the process in consultation with Justice Health in an affidavit recently filed in the NSW Court of Criminal Appeal, where the Crown is appealing against the "manifest inadequacy" of her sentence, handed down in January.

Amati was convicted of wounding with intent to murder, causing grievous bodily harm with intent to murder and attempting to wound with intent to murder.

Two people suffered severe injuries, including one man who suffered fractures to his nasal bone, eye socket and cheekbone, and a woman, whose skull was fractured when Amati swung the axe into the back of her head at the Enmore 7-Eleven.
