Emergency services were called to the scene just before 4pm on Sunday. Paramedics treated the woman and children before they were transported to Canberra Hospital in a stable condition for further assessment.

ACT Fire and Rescue and ACT Policing also attended the scene.

The crash is the likely cause of an outage in some parts of Banks, Conder and Gordon. Evoenergy is on route to investigate.

According to the energy provider's website, power is expected to be restored by 6pm.
