Flood cover is not automatically included in most Australian home insurance policies. It is typically an optional extra that you must actively choose and pay for separately. If your property is in a flood-prone area or you want comprehensive protection against natural disasters, you need to check your Product Disclosure Statement (PDS) and add flood cover if it is not already included. Without it, damage from rising water, overflowing rivers, or heavy rainfall that escapes normal drainage may not be covered, leaving you to pay for repairs out of pocket.

Flood Cover Is Optional in Australia

Unlike some other countries, Australian home insurers do not automatically include flood cover in standard building or contents policies. According to ASIC MoneySmart, you must request flood cover when you take out a policy or add it later. Some insurers bundle it into comprehensive policies, while others offer it as an add-on for an extra premium. Always read the PDS and the Target Market Determination (TMD) to confirm what is and is not covered under your specific policy.

What Counts as a Flood

The Insurance Council of Australia defines a flood as the covering of normally dry land by water that has escaped or been released from its normal confines, such as a river, creek, lake, or dam (Insurance Council of Australia, 2026). This definition matters because damage from storm water, which is rainwater that builds up before it enters a waterway, is often covered under a different part of your policy or not covered at all. If you make a claim and the insurer determines the damage was caused by storm water rather than flood, your claim may be denied unless you have both types of cover. Check your PDS carefully to understand the distinction and what each policy section covers.

Why Flood Insurance Matters

Australia has experienced severe flooding in recent years, particularly across Queensland, New South Wales, and parts of Victoria. Climate change is expected to increase the frequency and intensity of extreme weather events, including floods. If you own a home in a flood-prone area, such as near a river, creek, or low-lying coastal zone, the cost of flood damage can run into the tens or hundreds of thousands of dollars. Without flood cover, you are responsible for the full cost of repairs, replacement of damaged contents, and temporary accommodation while your home is uninhabitable. Even if you are not in a mapped flood zone, heavy rainfall can cause unexpected flooding, so it is worth considering cover regardless of your location.

What to Check Before You Buy

Before purchasing or renewing your home insurance, verify whether flood cover is included or offered as an option. Look for these details in your PDS:

  • Whether flood and storm water damage are covered separately or together.
  • The excess you will pay if you make a flood claim (flood excess is often higher than standard excess).
  • Any exclusions, such as damage from coastal erosion, tsunami, or actions of the sea (these may not be covered even with flood insurance).
  • Whether contents insurance includes flood cover or if you need to add it separately.

If you are unsure, contact your insurer directly and ask for a clear explanation. If your current policy does not offer flood cover and you want it, compare other insurers to find a policy that meets your needs. Request quotes from at least three insurers and compare the cover, excess, and annual premium. Premiums for flood cover vary widely depending on your property’s flood risk, location, and the insurer’s underwriting criteria.

Next Steps

Read your current home insurance PDS and check whether flood cover is included. If it is not, contact your insurer to add it or shop around for a policy that includes it. If you are buying a new property, check historical flood maps and consider flood risk before committing. For disputes about flood claims or policy terms, you can lodge a complaint with the Australian Financial Complaints Authority (AFCA), which provides free and independent dispute resolution for insurance matters.
