As a child growing up in a strict Jehovah's Witness household she was taught to obey her father as head of the family and warned that outsiders were "worldly people" who served Satan.

In a harrowing day of evidence before the Royal Commission into Institutional Responses to Child Sexual Abuse, the woman detailed how her father repeatedly sexually abused her and her three sisters.

The father, given the pseudonym BCH, was a respected figure in the church who would conduct door-to-door preaching and deliver talks from an elevated platform at his congregation's kingdom hall in Queensland.

At home the man became a tyrant, with the commission hearing that he would beat his daughter so hard with a leather belt she would bleed from the welts.

The woman, now 43 and using the pseudonym BCG, told the commission that her father repeatedly molested her.
