EMERGENCY workers were frustrated that too many people were taking risks during last week's flood emergency.

During the flood last week, the State Emergency Service was required to make 33 flood rescues in the Richmond and Tweed regions with 28 in the two days at the height of the flooding.

SES spokeswoman Heidi Groom said it was a "very high number" of rescues for a 48-hour period.

"Rescues could involve anything from cars breaking down in floodwater to medical emergencies," Ms Groom said.

"It just shows that people are taking unnecessary risks around floodwater.

"People should be taking more care.  It must be remembered that with a flash flood the water can go down as quickly as it goes up so people just need to show a little patience.

"We do have the people training and equipped to deal with rescue situations, but ideally we don't want to use them."

Ms Groom said one rescue involved using a boat to take paramedics to a residence and evacuating someone because of a medical emergency.

"In most cases the need for a rescue could have been avoided," she said.

The SES has continued to warn people not to cross flooded roads and to prepare for flooding at home with a flood preparation kit.

During the weekend, SES workers continued their education campaign when door knocking residence in flood affected areas of the Tweed, including Fingal, Chinderah and South Murwillumbah.

The volunteers were also gathering flood intelligence data and assessing damage.  

"All the feedback we got was quiet positive from the residents and businesses in the evacuation areas

"They were more than happy with our response and said they received regular updates on the flood situation."

Ms Groom said the SES was also happy with what it saw during the door knock.

"Most residents are very well prepared for floods.  Particularly those that have lived in the area for a long time," she said.

"They have seen it before."

SES Richmond Tweed region controller Simon Gregg said most people followed evacuation orders.

"We were very pleased with the response to the evacuation orders and thanks all those people who evacuated as directed," Mr Gregg said.

"Whilst evacuations can be an inconvenience, residents and visitors to the area need to understand that the safety of the community is the priority."

SES used text message and automated voice messages to landline phones to alert residents of evacuation orders.
