The 15-year-old was last seen at her Bundoora address about 11am yesterday.

It’s believed she may have been at St Kida Beach about 3pm yesterday.

Police and family hold concerns for Nhi’s welfare due to her young age.

Nhi is described as being about 158cm tall, with a thin build, long dark hair and dark eyes.

She was last seen wearing a black hoody, dark blue shorts, white Adidas runners and was carrying a black Adidas backpack.

Police have released an image of Nhi in the hope someone recognises her and can provide information on her current whereabouts.
