FAQ- National Flood Information Database (NFID)

What is the NFID?

The NFID is a 14 million point dataset providing flood risk data for all addresses in Australia. The NFID uses the Geo-Coded National Address File to determine address locations and then estimates the depth and frequency of flooding at that location. Each address includes an estimate of depth for flooding at 5%, 2%, 1% and Probable Maximum Flood, wherever the ICA has been able to locate government flood mapping relevant to the location. The NFID references flood risk as flood has been defined by the Insurance Contracts Act.

What is the NFID used for?

The NFID is used by insurers as one input to estimate the flood exposure that may exist at a buildings location. Most insurers refer to multiple sources of data in addition to NFID wherever possible.

How was the NFID created and how is it updated?

Version 1.0 of the NFID was developed in 2007 by the ICA. The work was carried out through a consortium formed between Risk Frontiers Ltd and WillisRe. The consortium company is called Risk Frontiers Flood Australia and is contracted by ICA to produce a new version of the NFID each quarter by incorporating new flood risk data sourced by the ICA from governments and agencies. The NFID is funded through annual mandatory levies on all members of the ICA who write property risks.

The ICA continually scans jurisdictions looking for updated flood data, for example the outputs of new flood studies undertaken by a local government. Once the data is made available to the ICA, the contractor uses the data to create updated depth and frequency points for impacted addresses. A new version of NFID is produced and released to license holders. At the same time, the ICA deploys a visualisation of the data into the Dataglobe, updates the MyHazards application and loads the raw geospatial data, supplied by the government, into the ICA’s geospatial library for use by licensed members.

What data is collected to go into the NFID by the ICA?

The preferred data description for inputs to the NFID are available here https://www.icadataglobe.com/why-insurers-need-data

Who can use the NFID?

The ICA holds a Master License for use of the NFID. The ICA issues Sub-Licences to staekholders in the industry. The Su-Licence sets out the conditions for use, limitations and responsibilities of all parties. Obtaining a sub-license requires an industry stakeholder to contribute financially to the NFID program (the Sub-license maintenance fee). Payment of the fee and holding an NFID Sub-License also entitles the stakeholder to access to all collected raw hazard data and use of all tools created by ICA concerning hazard exposures.

All members of the ICA who write property risks, with the exception of Lloyds underwriters, fund the NFID and can access all data.

Governments who make flood data available to the industry for use in NFID can also obtain an NFID Sub-License, at no cost from the ICA.

Does the NFID include overland flow data?


Does the NFID include climate change data?


Where can I see NFID data?

A basic version of NFID data is used in the MyHazards application for smartphones, no license is required for this level of access. A more advanced version of the data is available to visualise on the ICA’s Dataglobe service (available upon request). Accessing the entire dataset requires a license.

How do I get access to the NFID data and all of the raw datasets collected by ICA?

Assuming you have obtained a license to use NFID from the ICA, physical access to the data is established by registering at https://www.icadataglobe.com/request-access-to-dataglobe

Any staff member from a company or government agency who currently license the NFID will be given immediate access to the datasets.
