Residents of flood-affected Goodna to be initial priority for buy-back scheme, Reconstruction Authority says they will not be rushed

  Residents of flood-affected Goodna to be initial priority for buy-back scheme, Reconstruction Authority says they will not be rushed More than five months after the February flood disaster, more than 4,250 people across Queensland have registered their interest to have their homes raised, rebuilt or voluntary bought back.Flood-affected home owners in eastern parts of Goodna are being given "initial priority" for voluntary home buy-backs, with 31 owners having confirmed their interest so far.

Up to 46,000 people in Sydney could fail to evacuate if flooding comparable to that experienced in Lismore earlier this year strikes in the future, a report has warned.  

The findings of an independent inquiry, led by NSW chief scientist and engineer Mary O'Kane and former police commissioner Mick Fuller, will be released today after being handed to NSW Premier Dominic Perrottet more than two weeks ago.

The inquiry will back plans to raise the Warragamba Dam wall, arguing it could save lives and homes by giving people more time to evacuate.

As floodwaters hurtled towards Lismore, several rain and river gauges stopped working

  As floodwaters hurtled towards Lismore, several rain and river gauges stopped working Residents living upstream from Lismore say faults in the rain and river gauge network deprived them of potentially life-saving data as a catastrophic flood hit the New South Wales Northern Rivers in February. There are 27 rainfall and 19 stream level gauges in the Wilsons River catchment that provide data to the Bureau of Meteorology to help predict flood heights and develop forecasts.Residents also monitor the data directly via the bureau's website. When the February flood hit, one rain gauge was already broken and a further two rain gauges and six stream gauges stopped transmitting data during the event.ABC's 7.

The independent flood report estimates that by 2041 up to 46,000 people will live in high-risk flood zones in the Hawkesbury-Nepean Valley and could fail to evacuate in a one-in-1,000-year flood – like the one experienced in Lismore in February — and last seen in the area in the 1860s.

The report says that increasing the dam's capacity could reduce that risk by "holding back floodwaters" and "delaying peak flows".

It said increasing the capacity of Warragamba Dam could "provide a significant reduction in current risks to life and property" in the area.

The state government believes its plan to raise the dam's wall would mitigate floods by giving the dam about 14 metres of space above the current level to "hold back" extra water.

NSW SES launches new flood campaign in community languages targeting Sydney's north-west

  NSW SES launches new flood campaign in community languages targeting Sydney's north-west A new information campaign to help culturally diverse communities in Sydney's north-west deal with a flood crisis will help keep them safe, the NSW SES Commissioner says.From tomorrow, messaging in Arabic, Cantonese, Farsi, Korean, Mandarin and Punjabi will appear in videos, radio and social media content.

The plan has been criticised by environmental groups — who argue the Blue Mountains could lose its world heritage listing — and some First Nations people, who warn culturally significant sites would be destroyed.

Off the back of the report, the NSW government will also establish a Reconstruction Authority to oversee the rebuilding of housing and infrastructure in the wake of future disasters.

More than 6,000 homes were damaged in this year's floods, most of those in Lismore, with almost 1,500 of those severely damaged or destroyed.

Hundreds of people are still living in temporary accommodation in the flood devastated Northern Rivers region, with no certainty going forward. 

The ABC understands a proposal to dismantle Resilience NSW, with is currently tasked with rebuilding flood destroyed communities, would be put to cabinet.

The new authority, which the government intends to have in place by Christmas, would be tasked with procuring and managing funds from government and philanthropic sources, and distributing it to affected communities.

It would also be in charge of disaster prevention in high-risk areas across the state.

The full report, which is expected to give communities in the Northern Rivers region more guidance on where and how they can rebuild their homes, will be released today.

Lismore volunteer warns against plan to equip NSW locals to be first responders in a disaster .

He does not think the community should have to do that again.The so called 'tinny army' saved countless lives using privately owned jet skis and dingys, against the advice of authorities, as emergency services struggled to cope to demand.
