First Nations knowledge in Australian urban planning has moved from the margins of professional debate into the centre of climate adaptation research. Yet the practice has not kept pace with the evidence. First Nations Australians have actively managed this continent  not simply inhabited it for tens of thousands of years. Cultural burning shaped fire regimes. Seasonal ecological calendars governed land intervention. Waterway stewardship sustained catchments across generations.

The knowledge is real, place-specific, and increasingly validated by peer-reviewed science. So why does it still arrive late in the design process  tucked into an acknowledgement, listed in a consultation summary, or added as a footnote to a biodiversity report? The answer is not ignorance. Most planners and landscape architects are aware of it. The problem is structural: this knowledge gets treated as cultural context rather than technical input.

This article examines what genuine engagement looks like. It also draws on current research to show the practical value of First Nations land management for fire resilience, biodiversity, waterway health, and urban heat and argues that integration must begin at the brief stage, not the review stage.

Cultural Burning in Australian Urban Planning: What the Research Confirms

How Colonisation Restructured the Landscape

The disruption of traditional burning practices following European colonisation did not simply alter Indigenous culture. It restructured the physical landscape in ways that directly amplified fire risk. Moreover, this is not a contested claim it is what the environmental data consistently shows.

Research published in Nature Geoscience (Bird et al., 2024) traced fire regimes across 150,000 years using a sediment core from Girraween Lagoon near Darwin. Indigenous land managers deliberately shifted toward more frequent, low-intensity fires at least 11,000 years ago. Consequently, this maintained vegetation structure, reduced fuel connectivity, and enhanced biodiversity across tropical savannahs. When European colonisation ended that regime, fires became larger, later in season, and far more damaging to ecosystems.

Vegetation Changes and the Black Summer

Similarly, Mariani et al. (2022), published in Frontiers in Ecology and the Environment, provided the first quantitative evidence of what this looked like in southeast Australia. Before British colonisation, forests and woodlands contained fewer shrubs and more grass a direct result of Indigenous vegetation management through fire. After colonisation, shrub encroachment accelerated and fuel connectivity increased. Furthermore, the authors are direct about the consequence: this process amplified the scale and intensity of the 2019–20 Black Summer fires.

Why Cultural Burning Outperforms Hazard Reduction Burning

Cultural burns differ from standard hazard reduction burning (HRB) in ways that matter ecologically. Cultural burns are small, low-intensity, and patchy. They are lit under ecologically specific conditions not on an administrative schedule. As a result, they produce a mosaic of burned and unburned patches that reduces fuel load, stimulates understorey regeneration, and prevents catastrophic fire spread. HRB, by contrast, achieves fuel reduction but rarely generates this ecological mosaic.

A cross-cultural monitoring study at Wattleridge Indigenous Protected Area on the New England Tablelands (McKemey et al., 2021) makes this difference measurable. Cultural burning preserved mature plant populations of the threatened Backwater grevillea. However, the 2019 wildfire that swept through the long-unburnt control site destroyed 99.6% of mature individuals. All three fire types reduced fuel loads by comparable amounts. Nevertheless, only cultural burning left behind a structurally intact, multi-generational plant population.

Design Implications for Landscape Architects

Given this evidence, fire can no longer sit outside the design brief. Open space networks, ecological corridors, and urban bushland reserves must be planned with fire behaviour in mind from the outset. Landscape architects can advocate for culturally informed burning within land management plans, design fuel zones that respond to ecological conditions rather than administrative convenience, and most importantly engage Traditional Custodians at the site analysis stage.

Seasonal Calendars: Adaptive Intelligence That Fixed Schedules Cannot Replicate

A Different Logic of Time

Standard planning and maintenance schedules divide the year into twelve months with seasonal overlays. First Nations seasonal calendars operate from a fundamentally different logic. Rather than fixed dates, they are built from continuous ecological observation: plant flowering cycles, animal movement, rainfall shifts, and waterway behaviour. Many language groups identify between six and thirteen seasons annually, each defined by what the landscape is actually doing.

Woodward and McTaggart (2019) documented the Ngan’gi calendar from the Daly River region in detail. Knowledge holders identify thirteen seasons per annual cycle, and crucially, the timing of each season varies year to year in response to local conditions. That variability is the point the calendar adapts to Country rather than imposing a fixed framework on it.

Why This Matters as Climate Shifts

Climate change is making fixed scheduling increasingly unreliable. As a result, applying First Nations knowledge in Australian urban planning and land management offers something static systems cannot: ecological timing that responds to what is actually happening on the ground. CSIRO has co-developed seasonal calendars with the Gulumoerrgin (Larrakia), Ngan’gi, MalakMalak, Tiwi, Gooniyandi, Ngadju, and Kunwinjku peoples over more than 15 years. These calendars have been adopted across Indigenous land and sea management programmes to guide annual management plans and monitor ecological change (DCCEEW, 2021).

For planners and landscape architects, the practical step is clear. Where seasonal calendars exist for a project region, incorporate them into open space management plans, biodiversity strategies, and maintenance schedules as functional inputs, not symbolic references. Where they do not yet exist, commissioning them in partnership with Traditional Custodians represents a meaningful co-design investment.

Waterway Stewardship: Systems Thinking That Predates the Term

The Limits of Conventional WSUD

Water Sensitive Urban Design has significantly advanced how cities manage stormwater and urban water cycles. Nevertheless, it approaches water primarily as a flow problem something to be routed, filtered, slowed, and absorbed through engineered systems. Rain gardens, bioswales, and retention basins are valuable tools. Yet they tend to treat water as a challenge to moderate rather than a system to sustain.

A Relational Understanding of Water

First Nations water stewardship starts from a different premise. Catchments, floodplains, wetlands, and waterways are understood as interconnected living systems. The question is not how to manage what water produces it is what the system needs to remain ecologically healthy. As Woodward and McTaggart (2019) document, Traditional Custodians draw on inherited laws and knowledge to maintain the health of lands and waters as a reciprocal responsibility. Country deteriorates when not cared for. Communities are affected when that connection is severed.

Flooding, from this perspective, is part of a seasonal cycle that sustains riparian ecosystems not simply a hazard to contain. Wetlands function as ecological infrastructure: filtering water, recharging groundwater, moderating flow, and buffering against both drought and inundation. These are not philosophical positions. They have direct consequences for how catchment management plans are written and how urban water strategies set priorities.

Practical Planning Steps

When working on projects involving waterways or catchment-scale open space, engaging the relevant Land and Sea Council or Native Title body early improves ecological understanding of how the system functions as a whole. Many catchment management authorities in Victoria, NSW, and Queensland now have frameworks for incorporating First Nations values into water planning. These frameworks exist because they produce better outcomes making their use a technical decision as much as a cultural one.

Urban Heat and Biodiversity: Why Structure Matters More Than Coverage

The Limits of Standard Greening

Australian cities are losing ground on urban heat and biodiversity simultaneously. Street trees, green roofs, and bioswales are expanding. However, quantity alone is not solving the problem. Most urban greening programs treat vegetation as an aesthetic layer and biodiversity as a checklist requirement. Consequently, the result is landscapes that appear greener but do not function ecologically.

What Mosaic Landscapes Deliver

Cultural burning offers a different model. Mosaic burning creating diverse, multi-aged, structurally layered vegetation rather than homogenous plantings produces landscapes with far greater canopy complexity, understorey diversity, and ecological resilience. A mosaic that includes established canopy, regenerating understorey, and open grassy areas supports more species, provides more effective shade, and moderates temperature more successfully than a uniform street tree grid or a maintained lawn.

The Australian State of the Environment Report confirms this: Indigenous cultural burning supports native species regeneration, reduces invasive species, and maintains habitat connectivity through mosaic management (DCCEEW, 2021). These are the exact functions urban biodiversity strategies now seek to restore often at considerable cost, after ecological baselines have already degraded.

Integrating This Into Design Practice

Incorporating First Nations knowledge in Australian urban planning at the open space design stage in species selection, vegetation structure, edge management, and disturbance phasing addresses these functions as inherent design intent rather than retrofitted mitigation. This is not about replacing existing methods. Rather, it is about asking better questions during site analysis and brief development, and building the relationships that make better answers accessible.

Co-Design with Country: Putting First Nations Knowledge at the Centre of Australian Urban Planning

Consultation Is Not Co-Design

The language of co-design and Designing with Country has become familiar in professional circles. However, the substance has been slower to follow. Consultation happens after a project has set its direction and seeks input on details. Co-design happens before any design directions are defined when knowledge holders shape the questions being asked, not just the answers considered.

What the Evidence Shows About Current Practice

AHURI’s 2024 Final Report, Voicing First Nations Country, Culture and Community in Urban Policy (Davidson et al., 2024), found that current engagement approaches place an unreasonable burden on Traditional Custodians. They are under-resourced, overstretched, and experiencing consultation fatigue. Furthermore, the research conducted with the University of Sydney, RMIT, and UNSW grounds its findings in First Nations sovereignty and governance as the starting point, not as one consideration among several.

Davidson et al. (2024) are specific about what genuine co-design requires: relationships built before a project requires engagement; sustained across time, not contingent on a single deliverable; properly resourced by professional bodies, local governments, and development agencies; and supported by planning curricula that treat First Nations land management as substantive professional knowledge.

The Professional Opportunity

For landscape architects, the opportunity is direct. The discipline operates at precisely the intersection where this knowledge is most applicable managing living ecological systems, designing places where people and nature interact, and stewarding public land across time. Engaging seriously with cultural burning, seasonal ecology, and waterway stewardship makes the analysis more accurate and the outcomes more durable.

Make It the Starting Point

The case for First Nations knowledge in Australian urban planning is now well established. Research in Nature Geoscience confirmed that culturally managed fire regimes maintained Australia’s tropical savannahs for at least 11,000 years. Research in Frontiers in Ecology and the Environment provided the first quantitative evidence that stopping cultural burning drove the fuel accumulation behind the Black Summer fires. Moreover, field research at Wattleridge demonstrated that cultural burning preserves ecological structure in ways wildfire and standard hazard reduction burning do not.

None of this makes implementation simple. Cultural burning is place-specific and requires deep local knowledge. Seasonal calendars must be co-developed with knowledge holders, not borrowed from a template. Waterway stewardship involves governance frameworks that sit outside standard planning instruments. These are real complexities. They are not resolved by a single consultation session or a project-level engagement budget.

What they require is what the profession has generally been reluctant to commit to: relationships with Traditional Custodians built before a project requires them, sustained across time, and properly funded. Engage knowledge holders at the brief stage. Advocate within institutions for planning frameworks that place First Nations governance at the centre of decisions about Country.

Australia’s landscape was not a blank surface waiting for European design systems to organise it. That assumption has caused measurable ecological harm in fire regimes, in waterway function, in biodiversity, and in urban heat. The profession has the capacity to work from a different foundation. The knowledge is there. The starting point is building the relationships that make it accessible.
