The Insurance Council of Australia (ICA) has encouraged the NSW Government to look at a retreat of homes and businesses from areas such as North and South Lismore, as highlighted in the city council’s discussion paper, and says it’s important decisions aren’t delayed.

“A key consideration for government should be the time in which decisions are made to fund and operationalise a buy-back or land swap arrangement,” ICA says in a submission to a NSW Parliamentary Select Committee inquiry into the floods response.

Delays on making decisions about land swaps and buy-backs could lead to rebuilding in high-risk areas and “indirect issues relating to contractural obligations for insurers processing claims honestly, fairly and expeditiously”, it says.

“Broader considerations such as future insurability and lendability of any rebuilt or relocated home should be a key consideration during policy design,” ICA says.

IAG, in submissions to the committee inquiry and an independent inquiry commissioned by the Government, says it’s important to look at managed retreats in high risk areas before an event takes place.

“Given recent NSW flooding events, it is clear that the existing level of flood risks in some areas are not economically sustainable for communities,” it says. “Our concern is the risk in these communities will only worsen with further impacts from climate change.”

IAG says a key to the success of rebuilding in the Northern Rivers region is to significantly increase Federal and State Government funding to expand and refocus voluntary purchase schemes and to initiate a land swap scheme.

The insurer encourages local governments and planners to consider allocating or putting aside areas of land for relocation programs in the future, while the submissions raise the need to consider implications for people already in an area that is determined to be too high risk for future development.

ICA and IAG warn against overreliance on the 1% annual exceedance probability (AEP) threshold mandated under previous generations of planning guidelines.

“Reliance on this standard has assumed that the risk from larger events will be infrequent and minor enough to be generally accepted in communities,” ICA says. “Analysis of flood claim data indicates that newly built homes above the 1% AEP are sustaining an unacceptable level of damage.”

The 1-in-100-year measure doesn’t mean a property floods once a century, and in fact there’s a 50% chance of being flooded in 70 years and a 15% chance of being flooded twice in that time, the submission says.

IAG says a construction standard issued by the Australian Building Code Board for new construction in flood-prone areas is less stringent compared with specifications for bushfire prone areas.

“Bushfire construction requires the builder or landowner to undergo a Bushfire Attack Level (BAL) assessment, which instructs what materials can be used, what orientation and siting and what construction methodology are required to comply to the BAL assessed levels,” it says. “We believe flood prone areas should have a similar assessment or requirement incorporated into the building code.”

Insurers have also called for improved sharing of data and greater engagement with the industry on flood risk issues

ICA notes shortages of tradespeople and the under-supply of building products remain problems following impacts from the pandemic and a NSW skills qualification mutual recognition scheme is competing with other programs such ass the Queensland Government’s Tradies in Paradise initiative.

“More can be done to onshore international construction workers and address the affordability and access of construction materials required to repair and rebuild homes,” it says.
