Stacey Mitchell's body was found last December in a wheelie bin at a house in Perth, Western Australia, days after her family had reported her missing.

Ms Mitchell, who is from the West Moors area in Dorset, emigrated to Australia when she was 10-years-old.

The two women, who are to be sentenced in January, face a life term with a minimum of 15 years.

Ms Mitchell was staying with the women - Jessica Stasinowsky, 20, and Valerie Parashumti, 19 - in Lathlain, Perth, at the time of her death.

The two pleaded guilty to killing Ms Mitchell, at the Supreme Court of Western Australia on Monday.
