Cyclone and severe flooding checklist


Unpredictable and powerful storms are a part of life in the Territory so it’s important to be prepared.

Some simple planning can help you and your family in a natural disaster.

Prepare a household disaster plan and evacuation plan. Keep a list of emergency numbers and make sure important documents (passports, identification, some cash etc) are safe in waterproof containers.

The checklists below will help to ensure the continued supply of power and water services to your home during a cyclone or flood.

At the start of the season

  • Tidy up unsecured objects around your home and yard.
  • Trim trees and remove dead branches. However, if they are near powerlines, do not attempt to trim them yourself. Call us on 1800 245 092.
  • Remove debris from gutters and drains to avoid flooding.
  • If you have renovated during the dry/winter, make sure there are no exposed wires or power boxes that could cause electrical issues.
  • Free your overflow relief gully (ORG) from obstructions which could prevent it from working effectively.
  • Check that the downpipes from your roof are not connected to the sewer to minimise potential for sewage overflows.
  • Install a surge protector in your home to protect sensitive electronic equipment.

Before a cyclone or severe flooding

  • Have a cyclone kit ready. Cyclone kit lists can be found at
  • Fill containers, including bath and sinks, with water in case supply is cut.
  • If you are evacuated, turn off the electricity at the main switchboard and water at the meter.
  • Turn off and unplug electrical appliances at the power
    point, including computers, TV, DVD and aerial cables.
