This section deals with modelling the damage to infrastructure as a result
of the inundation described in the previous sections. 
The National Building Exposure Database (NBED) has been
created by Geoscience Australia so that consistent risk assessments for a range
of natural hazards can be conducted 
(footnote http://www.ga.gov.au/urban/projects/ramp/NBED.jsp). 
The NBED contains information
about buildings, people, infrastructure, structure value and building contents.
It is important to note here that the NBED contains information about
residential structures only.

Once the maximum inundation is calculated for each building, the resultant damage 
can then be determined as a function of its type and location from the coastline.

Impact on indigeneous communities are important considerations when determining
tsunami impact, especially as a number of communities exist in coastal regions.
These communities are typcially not included in national residential databases and
would be therefore overlooked in damage model estimates.
There is one indigeneous community located in this study area as seen
in \ref{fig:communities}. The population of the Bindibindi community is 140 and is 
situated in a potentially vulnerable location.
