A mother and daughter stabbed to death in their Toowoomba home, west of Brisbane, will be farewelled at a service on Wednesday.

A funeral service will be held on Wednesday for a mother and daughter stabbed to death in their home west of Brisbane.

The woman, 38, and her 12-year-old daughter died violent deaths at their Toowoomba home last week.

A boy, aged 16, has been charged with their murders and remains in custody.

A service will be held at Toowoomba’s Burstows Chapel from 12.30pm (AEST).

Relatives have asked mourners to donate money to a mental illness foundation rather than buy flowers.

The service is closed to the media.
