Yesterday the NSW State Emergency Service released a tsunami evacuation map for New South Wales. The map shows all the areas that lie –
- under 10-metres above sea level,
- are 1 km or less inland &
- are 10 km up an estuary.
This includes Marrickville, Dulwich Hill, Tempe, Sydenham, St Peters & Lewisham.
Other suburbs in our new municipality are also affected. These are Rozelle, Balmain, Balmain East, Birchgrove, Leichhardt, Annandale, Lilyfield, Haberfield & I think, Croydon.
Our neighbours at Summer Hill, Campsie, Canterbury, Ashbury, Hurlstone Park, Earlwood, Undercliffe, Wolli Creek, Bardwell Park, Mascot, Banksia, Rockdale & Botany are also affected. All the suburbs surrounding Botany Bay are included in the map & Sydney Airport is inundated.

The NSW SES website has comprehensive education on tsumanis & what to do, including a section specifically for schools. See – www.tsunamisafe.com.au
Since 2007, four tsunami events caused by earthquakes off the Solomon Islands, New Zealand, Chile & Japan reached the NSW coast.
The ‘NSW Tsunami Inundation Modelling and Risk Assessment’ report “outlines that the NSW coast is exposed to tsunami hazard, with inundation of low lying coastal land possible even with more likely events including those that have a 1 in 200 & a 1 in 500 chance of occurring in any given year (also known as a 200 & 500 year Average Recurrence Interval).”
The community will be alerted if there is a tsunami warning by radio & television broadcasts, social media, internet news & if you are on the beach, warning sirens. Also a text or recorded voice message may be sent to your mobile phone or a plane may fly lower than usual & broadcast a warning.
If a tsunami warning has been issued, the NSW SES says,
- “People are strongly advised to go to higher ground, at least ten metres above sea level, or if possible move at least one kilometre away from all beaches & the water’s edge of harbours & coastal estuaries.
- Take only essential items that you can carry including important papers, family photographs & medical needs.
- It may be in your own interests to walk to safety if possible to avoid traffic jams.
- If you cannot leave the area take shelter in the upper storey of a sturdy brick or concrete multi-storey building.”
They ask that you do not return to your home until an official all-clear has been given. AND, importantly, do not go sightseeing to the coast or the river.
