She was possibly wearing a tortoise shell hair band with a yellow ribbon. She had a thin face with freckles and hazel eyes, and two prominent front teeth. She was well spoken but stuttered when excited.

A letter written by Jane Beaumont two days before her disappearance shows her to have been a responsible, intelligent girl.
Dear Mum and Dad, I am just about to go to bed and the time is 9. I have put Grant's nappy on so there is no need to worry about his wetting the sheet. Grant wanted to sleep in his own bed so one of you will have to sleep with Arnna. Although you will not find the rooms in very good condition I hope you will find them as comfortable as we do. Good night to you both. Jane XXXShe had missed topping grade four at Paringa Park Primary School by only half a point.
