Forty roads were closed and some households and businesses across the local government area were without power for more than a week.

Preliminary estimates of asset damage and recovery, including green waste disposal, was in excess of $11 million.

A year on Port Stephens Council has acted on improvements to its response to extreme weather events.

Council will also call on the Federal Government to review its Natural Disaster Relief and Recovery Arrangements to achieve better effiicencies with a motion to the National General Assembly of Local Government.

The council's acting facilities and services group manager Greg Kable said all storm-related work in road reserves was nearing completion and the capital works program remained on track.

"In the days after the storm there were 10 crews involving 70 staff working around the clock to clear debris and close roads, and rangers were on the job clearing livestock and reuniting domestic pets with their owners, he said.

Mr Kable said Council had acted on criticisms following the April 2015 event put into effect in January.

"We had pumps and generators on site, ready to go and that is now part of council's response to east coast lows,” he said

“Importantly, these are improvements that have been recognised by residents and emergency services.”
