Flood, rainwater run-off and storm surge cover
We're making changes to how we cover flood, rainwater run-off and storm surge.
Now we automatically give you cover for flood, rainwater run-off and storm surge. This means you'll get cover for these events when you get a new policy or renew the policy you have now.
This applies for home, landlord and caravan policies purchased on or after 15 April 2018 or with a renewal date on or after 28 May 2018. See updated policy documents.
Here's what we mean by flood, rainwater run-off and storm surge
Flood is the covering of normally dry land by water that has escaped or been released from the normal confines of a lake, river, creek or other natural watercourse (even if they've been modified) or any reservoir, canal or dam.
Floods can occur when a long period of rain causes rivers, creeks and dams to overflow. This can affect large inland areas and spread over hundreds of kilometres. Although you may not have had rain in your area, a river can still break its banks because of heavy rain upstream.
Rainwater run-off is water that flows over the ground or backs up because of a storm.
It can occur when a large amount of rain falls in a storm and causes drainage systems to fail, spilling water into nearby areas and damaging property.
Storm surge is an increase in sea level because of an intense storm or cyclone and associated waves. Storm surge doesn't include sea actions caused by normal tidal movements like high tides or king tides.
How do we calculate your flood, rainwater run-off and storm surge premium?
Your premium is affected by the risk of your property being damaged by flood, rainwater run-off or storm surge.
To work out your risk, we use data from sources like the National Flood Insurance Database, hydrology and terrain mapping, council mapping and claims information.
We check and update our data throughout the year to make sure we use the latest information. That means your risk level may change from year to year.
The construction of your home, your sum insured, your excess and the kind of cover you choose also affect your premium.
