Chapter 2 – Snapshots: <strong>Green</strong> <strong>Square</strong> <strong>Histories</strong> in Brief<br />

<strong>Green</strong> <strong>Square</strong><br />

<strong>Histories</strong> in Brief<br />

2.1 The Pre-European Environmental<br />

Landscape in <strong>Green</strong> <strong>Square</strong><br />

Jason Doran<br />

The present-day appearance <strong>of</strong> the <strong>Green</strong> <strong>Square</strong> area hides<br />

an environmental history that is worth remembering and<br />

more importantly, worth restoring, in part at least. This area<br />

forms part <strong>of</strong> a unique environmental landscape known as the<br />

Botany Basin. Its story is one <strong>of</strong> adaptation to unusual environmental<br />

factors, and what emerged was a richly diverse,<br />

topographically distinct environmental landscape.<br />

<strong>Green</strong> <strong>Square</strong> was once covered in wetlands, dunes and dense<br />

shrubland, grading into low open woodland and forests. Its<br />

environmental history began more that 200 million years ago<br />

when the massive sandstone that underlies much <strong>of</strong> <strong>Sydney</strong><br />

was formed. Over the past 1.8 million years, windblown sand<br />

covered the Botany Basin, creating a vast dune system. But the<br />

element which came to characterise the area most was water: it<br />

ran southwards from the higher parts, pooling in lower places<br />

in the Basin, creating a network <strong>of</strong> swamps, pools and creeks<br />

which in turn flowed into Botany Bay.<br />

Water, sands, rocks and climate shaped the flora and fauna<br />

which flourished here: sedges, reeds and paperbarks in the<br />

swamps, grass trees, banksias, crimson bottlebrush and the<br />

spectacular Gymea lily in the scrub. The Botany Basin was<br />

home to the now endangered Eastern Suburbs Banksia Scrub<br />

vegetation community, remnants <strong>of</strong> which remain in isolated<br />

or protected locations. Nearer Centennial Park stood a dark<br />

and dense forest <strong>of</strong> ‘immense mahogany trees, blackbutt and<br />

other eucalypts’ as well as large cabbage-tree palms. Animals,<br />

reptiles, insects and birds in particular thrived in the wetland<br />

environment.<br />

This natural landscape was not only important for its own<br />

sake, it had cultural significance as well. Aboriginal people,<br />

the Eora, lived in and around <strong>Green</strong> <strong>Square</strong> for thousands <strong>of</strong><br />

years, hunting, fishing and foraging and creating social and<br />

cultural systems inseparable from country. After 1788 some<br />

Europeans were repelled by the area—considering it inaccessible,<br />

uninviting and ‘useless’—but others foraged and hunted<br />

here for food. It wasn’t until the late twentieth century that<br />

wetlands and their immense biodiversity began to be appreciated<br />

in the community generally, and acquire the cultural<br />

significance they now hold. By that time, a century and a half<br />

<strong>of</strong> industrial exploitation, drainage and infilling <strong>of</strong> swamps,<br />

building development and roads had long destroyed most <strong>of</strong><br />

the pre-1788 environmental landscape in <strong>Green</strong> <strong>Square</strong> and<br />

the wider region.<br />

However, remnant vegetation has survived in places, which,<br />

together with written records, can help us determine the<br />

biosphere that once existed in this area. This environmental<br />

history is essential in planning strategies for the future preservation<br />

and restoration <strong>of</strong> the region’s unique environment.<br />

2.2 Chimneys and Change:<br />

Post-European environmental impacts in <strong>Green</strong> <strong>Square</strong><br />

Scott Cumming<br />

The <strong>Green</strong> <strong>Square</strong> area is part <strong>of</strong> the larger environment <strong>of</strong> the<br />

South <strong>Sydney</strong> wetland corridor. This factor has been very significant<br />

in influencing post-European use <strong>of</strong> the area. From as<br />

early as the 1810s, local capitalists searching for power sources<br />

for their mills turned to the Waterloo/Botany area. Its relatively<br />

reliable water flow provided steam power for grinding<br />

grain and milling cloth.<br />

The area was also used as a source <strong>of</strong> water for the growing<br />

city. The pure water was diverted into tunnels and dams, and<br />

a pumping station was built on Lords Dam, which had been<br />

built for one <strong>of</strong> the early mills. The diversion and pumping,<br />

however, resulted in the drainage <strong>of</strong> the wetlands, as did<br />

further draining work to provide land for market gardens. By<br />

1869, the environment had changed radically: streams had<br />

almost ceased to flow, the swamps and their diverse plants and<br />

teeming wildlife were gone, and the area had become a ‘tract<br />

<strong>of</strong> barren sandhills’.<br />

The natural run-<strong>of</strong>f system from Waterloo Swamp to Shea’s<br />

Creek, the Cooks River and Botany Bay was admirably suited<br />

the purposes <strong>of</strong> industry: it was simply treated as an industrial<br />

waste drain. These waterways were soon polluted by foul water,<br />

refuse and ‘thick slimy matter’ from woolwashes, tanneries,<br />

boiling down establishments and abattoirs, and later from<br />

sawmills, foundries, soap and candle works and many more.<br />

The area was also used as a waste drain for sewage. From 1882<br />

to 1916 the southern outfall sewer system carried the southern<br />

suburbs’ human waste from Surry Hills to a sewerage farm on<br />

the northern bank <strong>of</strong> the mouth <strong>of</strong> the Cooks River. Part <strong>of</strong><br />

this system was an uncovered channel.<br />
