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).

This document reports on the proceedings and outcomes of a flood vulnerability workshop held at RMIT University in Melbourne on 14 June 2018. The workshop was convened as part of a research utilisation project under the Bushfire and Natural Hazards Cooperative Research Centre (BNHCRC) project entitled {\textquoteright}Costeffective mitigation strategy development for flood prone buildings{\textquoteright}. Key workshop aims were to finalise the project scope with key stakeholders, establish a Project Steering and identify case study communities for consideration. The research utilisation project entails working with a variety of stakeholders with the aim of translating detailed flood vulnerability information into practical guidance for flood risk managers. It involves developing and testing a number of resolution options (from asset specific vulnerability assessments to more generalised methods) in a series of case studies. The workshop structure featured presentations and discussion following a logical flow from context setting, scope refinement and consensus through to governance and next steps. The key workshop aims described above were achieved and a series of {\textquoteleft}next steps{\textquoteright} were identified and documented in this report.

The motivation for this project arises from the experience and observations made during the 2011 and 2013 floods in Australia, which caused widespread devastation in Queensland. Considerable costs were sustained by all levels of government and property owners to effect damage repair and enable community recovery.

A fundamental reason for this damage was inappropriate development in floodplains and a legacy of high risk building stock in flood prone areas. The vulnerability and associated flood risk is being reduced for newer construction by adopting new standards (ABCB, 2012), building controls and land use planning, however, the vulnerability associated with existing building stock remains. This vulnerability contributes disproportionally to overall flood risk in many Australian catchments.

The Bushfire and Natural Hazards Collaborative Research Centre (BNHCRC) project entitled {\textquotedblleft}Cost-effective mitigation strategy development for flood prone buildings{\textquotedblright} aims to address this issue and is targeted at assessing mitigation strategies to reduce the vulnerability of existing residential building stock in Australian floodplains. The project addresses the need for an evidence base to inform decision making on the mitigation of the flood risk posed by the most vulnerable Australian houses and complements parallel BNHCRC projects for earthquake and severe wind.

This annual report contains a summary of 12-month research undertaken by 4 partner institutions towards the development of cost-effective seismic retrofit methods for vulnerable Australian buildings. Progress has been made in 3 complementary fronts to:
1) Understand the seismic vulnerabilities of existing unreinforced masonry (URM) and limited ductile reinforced concrete (LDRC) buildings and methods to address them through seismic retrofit;
2) Risk assessment of the building stock through development of an economic loss model; and
3) Advance an end user focused research utilization project in the area of community risk reduction. This is done through an Earthquake Mitigation Case Study for the historic town of York in Western Australia.

The first of the above components is being researched in the Universities of Adelaide, Melbourne, and Swinburne. This work includes investigation of existing building seismic capacities and development of retrofit techniques. The second area is being studied by Geoscience and the work includes estimating direct and indirect losses associated with building damage and benefits from seismic retrofit. The last component is being conducted utilizing the research findings in the two other areas in collaboration with the Western Australia Department of Fire and Emergency Services, York Shire Council and its residents. Finally, using the new damage loss models and costings for seismically retrofitting buildings, recommendations are made for the development of seismic retrofit guidelines and policy based on the strong evidence base being developed by this CRC project team.
