Environmental Guide to The Tweed Coast

An extract from "An environmental guide to the Tweed Coast".  For further details please contact Tweed Shire Council.

Location and Climate:

The Tweed Coast stretches 37km from Point Danger in the north to Wooyung in the south.  Long sandy beaches are divided by prominent headlands and small estuaries.  The climate is described as humid warm-temperate with warm summers and mild winters. 

Geology:

Between 20 and 23 million years ago, molten lava from the Tweed Shield Volcano erupted and flowed through the landscape.  It spread south to Byron Bay and Lismore and north to Mt Tamborine and eastwards out to sea.  What now remains are the Tweed's familiar landmarks such as Wollumbin (Mt Warning) and the surrounding mountain ranges.  Another well known landmark is the hexagonal columnar basalt rocks at Fingal Headland.  The rich red soils on the Cudgen plateau behind Kingscliff have also resulted from long-term weathering of basalt rock.

The other headlands of the Tweed Coast date back to a time well before the existence of the Shield Volcano.  The rocks which make up these headlands are not volcanic but ancient sedimentary deposits in excess of 400 million years old.

Flora of the region:

  • Riparian zone vegetation
  • Coastal (wallum) heath
  • Littoral rainforest
