Conservation Council launches campaign to preserve Western Edge

Molonglo should be the end of the road for urban development in Canberra’s west, ACT Conservation Council executive director Simon Copland says.

Dr Copland was speaking at the launch of a council campaign to ensure the preservation of the so-called Western Edge, a 10,000 hectare stretch of land from Belconnen to Tuggeranong that the government has been looking at for more than a decade.

In the lead-up to the mid-2027 deadline for the government to set an urban growth boundary for Canberra, the council wants to ensure there are no carve-outs for new suburbs beyond Molonglo or Weston Creek.

In April, the Legislative Assembly supported a motion from Greens Deputy Leader Jo Clay, which called on the government to agree to release an amendment to the Territory Plan to establish the urban growth boundary by June 2027.

Dr Copland said while some areas had higher conservation values than others, all of the Western Edge should be preserved.

He said most of the Western Edge was box woodland and would be near impossible to develop.

“That’s one of the big issues. To develop out there you would inevitably have to destroy quite significant areas of woodland, which we oppose, particularly given it’s a threatened ecosystem,” Dr Copland said.

“We’re also saying we should not be building there because it’s just not good for the future of the city to be continuing to sprawl in this way.”

Dr Copland said it was much better for residents to be close to services, the city and town centres rather than building suburbs an hour’s drive from the CBD.

He said Canberra covered the same sized area as metropolitan London and there was huge capacity for decent infill development that was less of an impact on the environment.

The government is continuing its investigations into the Western Edge, some of which it land-banked somewhat controversially last decade before having to establish a boundary.

As well as possible new suburbs, the studies will identify areas suitable for new nature reserves, environmental offsets, heritage conservation, other uses such as rural, broadacre, infrastructure, transport and services.

Dr Copland said the campaign, including a Legislative Assembly petition, wanted the government to rule out any development on the Western Edge lands.

The petition calls for the Western Edge to be kept outside the ACT urban boundary, removed from development plans and for it to be sufficiently protected and managed for its ecological, cultural and recreational values.

The council views the Western Edge as a natural urban and bushfire buffer, a fauna and flora sanctuary, recreation area and a place of Ngunnawal history and culture.

Dr Copland said the campaign was a proactive measure to push the government to take the Western Edge off the development table.

The council is also calling on community members to lobby their MLAs.

I would prefer to see Kowen developed before the Western Edge, but if it was to be developed, then it should only be on old farmland.

Con Council, have another good look at that map. Do you seriously think Canberra can be grown past 800,000 and they won’t commandeer the Edge? Be real.

Every few months someone argues that Canberra should look more like Bergen, Copenhagen, Freiburg etc, with high-rise apartments crowding the city centre. The problem is Canberra was never designed that way, and pretending otherwise is wishful thinking.

From the start, planning rules locked up ridges, reserves, hills, grasslands and nature strips. Development is banned even on land close to Civic, such as Black Mountain surrounds, O’Connor Ridge and the ground between Mount Ainslie and Mount Majura. In other cities these areas would be full of housing or offices. Here they remain off-limits.

That decision shaped the city. Instead of one dense core, Canberra grew as a network of centres, Tuggeranong, Belconnen, Gungahlin, Woden, each with its own jobs, shops and services. It is more like a cluster of small cities than a compact emerging metropolis.

This design has negatives but also benefits. The green buffers make Canberra liveable and underpin its “bush capital” character. But the trade-off is density. Calls to copy other high-rise cities ignore that vast tracts of land near the centre will never be developed.

If Canberra wants more housing and better sustainability, the focus should be on where density is possible: taller buildings around existing centres, infill along transport corridors, and smarter use of serviced land. Civic will never become Sydney’s CBD because geography and planning forbid it.

Canberra’s spread-out, polycentric model is both burden and advantage. The city will never be Copenhagen or Amsterdam, but with clear planning it can grow into a more organised, effective and affordable version of itself.

That’s simply not true that just because it’s always been done this way that it can’t be done differently now. Certainly we have to live with the legacy of low density planning – but (to use one of your examples) i encourage you to google Copenhagen’s five finger model of growth – based around public transport spines with green belts in between. The average height of buildings in Copenhagen is around 3-5 stories – hardly high rise at all. Good, dense, livable, walkable communities are possible in Canberra – but we have to choose them over the same old car centric developments that have failed for 50 years.

bj,
Thankyou for your common-sense comment.

There are too many left-of-centre politicians in the Assembly who seem to continually preaching that we need to model this city on the likes of Copenhagen or Amsterdam. No, Canberra is not the size of a postage stamp. No, we were not designed

As seen in the comments, there are those who argue that the Western Edge is already occupied. Logically, this would then mean that every piece of undeveloped land within the Territory is probably also occupied by some animal, creature or critter and the only developments should be up.

Infill is the logical alternative, albeit that probably also ruffles the feathers of those with interests in horse-paddocks, possibly hampers views and changes the character of inner suburbs- the old NIMBY argument.

Why are there too many left of centre politicians in the assembly?

The assembly ultimately reflects the voting preferences of the community. So in that regard, whatever they’ve chosen reflects broadly the desired representation.

I remember hearing about how Zed had a plan to build another town just over the Murrimbidgee River which wasn’t a popular idea. I thought it sounded exciting but yeah, that Bushland needs to be preserved. However if they want people to live and work here, build homes for homeless people…they’re going to have to expand the borders. The ACT is too small.

This campaign is about the area to the east of the Murrumbidgee.

Conservation Council ACT should be defunded. That area can contain both new suburbs and nature reserves.

I’m not saying we should have open slather development in this area, but large parts of it are cleared horse paddocks of questionable conservation value and are closer to town than many existing Canberra suburbs.

Canberra needs to manage its human population and stop the urban sprawl. The Western Edge is already being used by wildlife. The Office of the Commissioner for Sustainability and the Environment’s report “Close to the Edge” strongly recommends the Western Edge not be developed because it will destroy critically endangered trees and native grassland.

Stop calling them ‘conservationists’ but what they really are – ‘anti progressives’.

Yeah, nah. It’s not about stopping progression, it’s about stopping us from turning into a Blade Runner landscape.

“Urban Infill” the same mantra that will make Canberra’s tram and bus systems economically competitive. “Urban Infill” the same planning that removed most carparks from Civic. “Urban Infill” the same push to make profits by commercial development of the foreshores of out lakes. “Urban Infill” the doctrine that creating congestion will somehow reduce pollution, when we all know stop-go traffic pollutes ten times more than free flowing. “Urban Infill” that green washed term that justifies making our city have all the problems other cities have, instead of enjoying the differences the planners originally proposed.

Why do buses or trams need to be ‘economically competitive’? They are public transport after all.

Let’s spend 5 million dollars on a bus consultant that does nothing…

It should be developed.

No it shouldn’t, we need that natural landscape. What should happen is the borders of the ACT should be expanded. They we can start building towns and places for people to live.
