Significant financial loss in terms of cost of rebuilding or repair and loss of function of property (e.g. commercial activity, rental, relocation of residents, etc.), has been documented following recent severe tropical cyclones impacting the Australian coastal communities. These damage investigations estimate that the wind speeds in these events were less than the Australian building standard{\textquoteright}s design level wind speed for the regions impacted. Analysis of insurance claims data highlights issues with wind driven rain water damage. Additionally, investigations of the damaged buildings along with analysis of claims data reveals a high proportion of the losses are associated with contemporary construction as opposed to pre-current code buildings.\ 

Education and awareness of consequences of such failures (e.g. damage to property and risk to life) is required in all steps of the building process (regulation, design, construction, certification and maintenance) and by all parties (designer, builder, certifier, and owner).

Modelling the vulnerability of houses in windstorms is important for insurance pricing, policy-making, and emergency management. Vulnerability models for Australian house types have been developed since the 1970s and have ranged from empirical models to more advanced reliability based structural engineering models, which provide estimates of damage for a range of wind speeds of interest. This paper describes recent developments in the engineering based vulnerability modelling software: {\textquoteleft}Vulnerability and Adaption to Wind Simulation{\textquoteright} (VAWS), which uses probability based reliability analysis and structural engineering for the loading and response coupled with an extensive test database and field damage assessments to calculate the damage experienced by selected Australian house types. A case study is presented to demonstrate the program{\textquoteright}s ability to model progressive failures, internal pressurization and debris impact.
