Flood modelling should inform the conversation, not end it

2026-07-27

Member for Ballina, Ms Tamara Smith MP has applauded the extraordinary level of community engagement at this week's Northern Rivers Resilience Initiative drop-in sessions, saying the turnout demonstrates just how important future flood mitigation remains to local communities.

Hundreds of residents across the Northern Rivers attended sessions in Kyogle, Casino, Lismore, Ballina, and Woodburn to talk about the findings of the Northern Rivers Resilience Initiative’s recent report, published in June.

"Four years on from the catastrophic 2022 floods, people remain deeply invested in finding solutions that actually protect our community and livelihoods," Ms Smith said.

Ms Smith said the sessions also highlighted the importance of distinguishing between the scientific work undertaken by CSIRO and the important policy decisions that now confront governments.

"The CSIRO's role was to develop a sophisticated hydraulic model of the Richmond River catchment and use it to test a range of flood mitigation scenarios.”

"The modelling tells us what is technically possible, but it is the government’s role alongside communities to decide which options deliver the best overall outcome for our community and future generations."

Ms Smith said the value of the work extends well beyond the specific projects examined in the report.

"For the first time, we have a catchment-wide modelling tool that allows decision makers to test ideas and see their impact before making major investments.”

"That capability will be priceless as we continue adapting our communities to future flood risk, whether we're assessing these proposals or completely different ones in the years ahead."

Ms Smith acknowledged that the sessions brought together people from all walks of life with different perspectives about how the Northern Rivers should respond to future flooding.

"Flood policy is deeply personal in our region, it affects people's homes, businesses and the environment. During these sessions, there were clearly strongly held and often competing views, and that's understandable. These important conversations have a vital role to play in ensuring that future flood adaptation plans are community centred and informed by the best available scientific data.”

Ms Smith said the report and our community should help inform what is ultimately a broader public policy discussion.

"Science can help us understand what may reduce flood impacts, but it can't tell us what governments should prioritise.”

"Those difficult decisions require policy makers to weigh up costs, environmental impacts, agricultural impacts, community expectations, and the number of homes that could be better protected.”

"It’s important that these conversations continue to happen outside of these sessions, where people and governments ask themselves, what will bring the best possible outcome to a scenario that will continue to impact communities here in the Northern Rivers and across Australia."

“Do we invest primarily in large-scale flood mitigation infrastructure, or should more funding go towards house raising, adaptations and stronger planning controls? Is the right answer a combination of all of these or something else entirely.”

"These are difficult questions and conversations but can now be based on a combination of personal experiences and far stronger scientific data than we've ever had before."
