Anyone requiring flood assistance (food supplies, medical emergencies), should contact the SES either by phone 132 500 or via the SES website https://www.ses.nsw.gov.au/
If your communications are out and all you have is Facebook, the Northern Rivers SES Facebook page https://www.facebook.com/NSWSESRichmondTweed is being monitored and you can leave a comment that includes your name, address contact details and assistance required for the SES to action.
