Homebush Bay Perambulations I: A Walk through ‘Toxicity’ … Munitions Dumps and Toxic Mounds

Bushwalking, Environmental, Heritage & Conservation, Social History

The north-western part of Homebush Bay in Sydney’s west was once a backwater of swampy industrial and military dumping grounds and wastelands. The rubbish dumps are still there but no longer visible and the entire surface area of the Bay now boasts a diverse range of interesting walks for the enthusiastic pedestrian. The network of walkways allow you to commence a walk in Homebush Bay* from various points of the compass … we shall start with a walk from the north-west commencing at Silverwater Bridge and throw in some digressions and let’s see what we can unearth.

As you set off by foot on the south bank along the pathway you can see across the River the predominantly low-level housing of Ermington and Melrose Park. There is not much river traffic around this part of the waterway but expect to see the green-and-white Rivercat glide by at regular intervals.

The first item of historic interest we encounter is the former Royal Australian Navy site, Newington Armory. There is a modern (‘Armory’) cafe, an older shop that also sells coffee and some play facilities here, near to the naval depot entrance. The entrance area is much as it was when the Navy abandoned the site in 1999 – still standing is an 1897 brick gatehouse (also known as “the cooperage”), with a rail track leading down from the gate to where the wharf used to be. Two old, grey-toned cranes (circa 1960s) stand fixed in time on the edge of the river.

The Sydney Olympic Park Authority describes the Armory site as it exists today as “compris(ing) a range of historically significant natural and cultural features including former army and navy ammunition storehouses, workshops, offices, small gauge railway and other infrastructure associated with the operation of a naval armament depot”¹. One hundred years ago (1916) it was a military powder magazine and five years after that a munitions store for the navy.

When the navy moved out there were skiploads of old armaments and other dangerous pollutants lying around the depot, so the department simply buried them and fenced off a large section of the site from the public. Other sections of the former naval property still have limited access for commercial activities on the weekend only (eg, rides on a historic electric locomotive which had been used for moving armaments around the ordnance depot). Blaxland Riverside Park nearby has flying fox rides and tunnel slides. Not far from here is the new Newington housing estate.

Continuing down the waterfront path, you come to a side path next to a high electricity tower. This bush-lined path (named in honour of paralympian Louise Sauvage) can be either a digression to take in the view from the second highest point in the Bay (after the Treillage), or an another route to the Sydney Olympic Precinct (railway station) via the lush Narawang Wetland and Haslams Creek.

There’s a steep, linear walk up a very large conical-shaped earth mound full of dangerous chemicals and other toxins² buried under several layers of top and middle soil … atop this geographical marker (Bay Marker) is the best view around here – a 360-degree panorama incorporating the river, the uniformed high-rise of Rhodes and Liberty Grove and the numerous Olympia stadia. Steeply descending the mound trail to the bottom you immediately ascend again, this second hilltop not as steep as the mound but with a plateau at the top, bears the name ascribed to it by the local,
Wan-gal clan, Woo-la-ra (= lookout).

From the high ground of Woo-la-ra you have a choice (several choices in fact): you can take the path down to Hill Road where you can walk along the forest trail parallel to Hill Road**. The Sydney Olympic Park Wharf is about one kilometre away, where you can catch the ferry back to Circular Quay or west to Parramatta.

We decide to continue the path for a further 2.5km through the Millennium Parklands down to Haslams Creek. Here on the south-eastern shore of the Creek there is another high mound known as
Kronos Hill, and also full of hidden toxic surprises³. You can follow a staggered, concentric trail up to the summit and be rewarded with sweeping 360-degree views of the Olympic Precinct (Allphones Arena and ANZ Stadium are both in the immediate foreground). From atop Kronos Hill it is only about half-an-hour walk’s back to the Olympic train station.

* “Homebush Bay” strictly historically speaking refers to the inlet, the body of water, off Parramatta River. The area that is now generally thought of as Homebush Bay (including Wentworth Point and the Sydney Olympic Park) was described in the early part of the 20th century as being part of “Lidcombe North”. The name “Homebush” itself derives from D’Arcy Wentworth who was granted a large land grant in the area in 1810, literally “his home in the bush”. ‘Homebush out to make a point’, Daily Telegraph, (Sydney), 04 January 2009, www.dailytelegraph.com.au

** Optional diversion: you might consider a side trip from the corner of Bennelong and Hill. From the intersection its about 400 metres to the Olympic Archery Field … catch a look at a bunch of would-be “Robin Hoods” in “bow and quiver” action (not a skerrick of Lincoln green in sight though, I’m afraid!).

³ Haslams Creek is heavily polluted with toxins (especially dioxins) as are all of the waterways and wetlands around Homebush Bay. Largely this is a direct result of chemical pollution by the Union Carbide/Timbrol Rhodes Plant between 1949 and 1976. The giant chemicals manufacturer poured the waste by-products of dioxins as well as other toxic landfill along the shoreline of the Bay. This practice (unbelievably) was sanctioned by the Maritime Services Board on the grounds that it “reclaimed stinking wetlands for a useful industrial purpose”. Consequently the US Environmental Protection Agency in 1994 ranked Homebush Bay as one of the five worst dioxin hotspots in the world, ‘A race against toxins’, The Irish Times, 19 August 2000.
