Councils are increasingly vigilant about building on floodplains after several catastrophic events but NSW Premier Chris Minns says major changes will be implemented to ensure inappropriate approvals don't slip through.
Mr Minns said the state government would have more to say before the end of the year regarding Sydney's planning processes and whether it would consider banning new approvals on floodplains, particularly in the city's northwest.
"Part of the reason why the government is so focused on infill urban consolidation - that means more density close to the city - (is) because we acknowledge that with increasing immigration (and) more people coming into the Sydney basin, they have to go somewhere," he told reporters on Wednesday.
