Infrastructure within and between cities and settlements is critical for activity across all sectors, with interdependencies increasing exposure to climate hazards . Previous planning horizons for existing infrastructure are compromised by now having to accommodate ongoing sea level rise , warming and increasing frequency of extreme rainfall and storm events . There is almost no information on the costs and benefits of adapting vulnerable and exposed infrastructure in Australia or New Zealand. Given the value of that infrastructure and the rising damage costs, this represents a large knowledge gap that has led to an adaptation investment deficit.
