This report has described the impact to Onslow from a tsunami
generated by a Mw 9 earthquake on the Sunda Arc subduction zone 
occurring at Mean Sea Level. 
There is no knowledge of the return period for this event. The
modelling methodology, assumptions and data sources which are
required to determine the impact to Onslow have also
been described. 
As discussed in Section \ref{sec:issues}, there are issues
with the underlying data set which may have vertical inaccuracies
of approximately 1-2m. As a result, these results should be considered
preliminary. 
These scenarios will be revisited once the probabilistic models
are complete so that a suite of tsunami impact assessments can be made.
It is therefore imperative that suitably accurate onshore data
be made available to raise confidence in the impact assessments.

Future activities to support the impact studies on the North West Shelf
include:

\begin{itemize}
\item Sourcing of data sets
\item Investigation of solution sensitivity to cell resolution,
bathymetry and tsunami source uncertainties
\item Location of boundary for simulation study area
\item Investigation of friction coefficients
\end{itemize}
