Let your garden tell a different story. One of place, kinship, wildness, and gentle repair.

Little Girl in the Garden – Bringing the Natives Back Home

A wild-ish backyard story from Bundjalung Country

I’d like to start by acknowledging the Traditional Custodians of this land, the Bundjalung people. This garden grows on their Country — always was, always will be. I pay respect to their Elders past and present, and to their deep knowledge of this landscape, its rhythms, plants, and seasons. That knowledge is still here, in the soil and the trees, and in how we care for this place.

Big, empty lawns come from British colonial ideals, where wealthy landowners in England used open grass to show control, status, and "civilised" order. When colonists arrived in places like Australia, they brought this aesthetic with them, clearing native vegetation to create neat lawns as a sign of ownership and respectability. The front lawn became a kind of stage — not for growing food or connecting with land, but to display tidiness and dominance.

But these lawns often displaced thriving ecosystems and required constant upkeep — water, mowing, chemicals — for little ecological return. Now, many are questioning that legacy, turning lawns into native gardens, food patches or wilder, more meaningful spaces that support life and connection instead of just appearance.

The tradition of front gardens as open, mown lawns comes from British colonial landscaping ideals. In 18th and 19th century England, aristocrats showcased wealth by surrounding their homes with expansive, manicured lawns. These lawns were deliberately open — not for food, not for shelter, but as a visual display of order, leisure, and dominance over wild nature.

When the British colonised places like Australia, they brought this idea with them. In settler towns and suburbs, the front lawn became a symbol of civility and control — a way to show you were respectable, modern, and had “tamed” your patch of land. Open space also served a practical colonial function: it allowed surveillance of the street and a clear visual boundary between public and private realms.

But the downside? These lawns usually replaced diverse native ecosystems and traditional land practices. They take water, fertilizer, and mowing — and they don’t do much for habitat, cooling, or community connection.

Why Do People Have Empty Lawns?

Large, mown grassy lawns became popular during English colonial times as a symbol of wealth, control, and European identity. In England, only the very wealthy could afford to keep large areas of grass trimmed short, as it required paid labour or grazing animals. Lawns became associated with power, civility, and dominance over nature.

When the British colonised lands like Australia, they brought this landscape ideal with them. Clearing native vegetation to create open lawns was a way to "tame" and "civilise" the land — a visual expression of ownership and dominance, ignoring the fact that these lands were already cared for and shaped by Indigenous peoples for thousands of years.

In settler suburbs and farms, lawns became a marker of "success," privacy, and conformity to Western aesthetics. But they often displaced native ecosystems and required high water use, chemicals, and ongoing maintenance — all to uphold a European ideal that was never ecologically suited to the land.

Three years ago, we made a simple but transformative decision — to fill our garden with native plants. What started as a few humble tube stocks from the local nursery has grown into a thriving, ever-evolving sanctuary that brings us joy every single day. We’ve lost a few special species during rough weather, like Cyclone Alfred, but nature has filled the gaps in its own way.

Inspired by the Ballina Urban Garden Guide, the incredible biodiversity of the Northern Rivers, and my own work as an environmental consultant, we committed to planting species native to this region. Our garden is now home to grevilleas, lomandras, tea trees, wattles, callistemons, and coastal rosemary. We’ve planted paperbarks and gums, Davidson plums, native palms, egg-and-bacon peas, ferns, paper daisies, and even a striking giant candle banksia. There are grass trees anchoring corners of the yard like ancient sculptures. all of these native are called a different name in Bandjalung. Everything was chosen for its ability to thrive in our coastal climate and support local wildlife. Slowly, with mulch, care, and time, the garden took shape — wild, purposeful, and full of soul.

It’s not just a garden — it’s a living, breathing ecosystem. Rainbow lorikeets chatter through the grevilleas every morning. Blue-tongue lizards soak up the warmth. Native bees buzz among the trea tree blossoms. Rosellas rest in the upper canopy, and frogs croak in the undergrowth on rainy nights. The neighbours often stop to comment on how lovely it’s become — it really does change the feeling of the whole street.

But the best part is what it’s brought to my children. It’s their playground, their classroom, their wonderland. They collect seed pods, grow herbs, build fairy houses beneath the ferns, and learn the names of the creatures who’ve moved in. They see firsthand how everything connects — the trees, the insects, the birds, the soil. There’s joy, simplicity, and a quiet kind of learning that only comes from being in nature.

And truly, anyone can do this. Whether you have a sunny balcony, a nature trip  a tiny patch of grass, or a full fromt our backyard — planting local native species can restore habitat, and reconnect you with this beautiful land we live on. The Ballina Urban Garden Guide is a wonderful place to start, full of plant ideas and design tips tailored to our region. Several of our friends have followed our lead, and even I’m surprised by the transformation in just two short years. It makes their homes feel more alive.

Every season brings new colour and energy — I still can’t get over how long the grevilleas flower. Every week we pick a bunch of fresh native blooms to bring inside. And there’s nothing better than seeing the garden grow, shift, and bloom alongside our family.

So if you’re thinking about planting or replanting, let your garden tell a local story. One that welcomes wildlife, sparks wonder, and gently returns something to this land we call home.

This is just on a small suburban block the options for hinterland living are multifold.



Protecting Our Waterways Starts at Home: What You Can Do to Keep Wastewater Clean

By Taisa Baars – Environmental Health Scientist, Byron Environmental Consulting

In the Northern Rivers and across regional Australia, many homes rely on on-site wastewater systems — septic tanks, aerated treatment systems (AWTS), and absorption trenches — to manage household sewage. When functioning well, these systems safely treat wastewater and return it to the environment. But when they fail, the consequences can be serious: pollution of creeks, groundwater, and even drinking water supplies.

Recent inspections have shown that many systems are aging, undersized, or simply not maintained. Stormwater runoff entering tanks, cracked lids, broken pipes, and overloaded trenches are just a few of the issues we’re seeing — and they all risk leaking untreated effluent into nearby soils and waterways.

The good news? Every household can take action to protect our shared environment.

5 Simple Ways to Protect Your Waterways:

1. Be septic-smart with what goes down the drain
Avoid flushing anything besides human waste and toilet paper. Wet wipes, sanitary products, and even "flushable" items can clog systems and shorten their lifespan.

2. Watch your water use
Excess water overloads systems and reduces treatment efficiency. Space out laundry loads, fix leaking taps, and consider installing low-flow fixtures.

3. Divert stormwater away
Keep gutters, roof runoff, and paved surface water well away from septic tanks and trenches. Stormwater entry dilutes treatment and can flush solids into trenches.

4. Service your system regularly
AWTS units require servicing every 3 months by law in NSW. Even septic tanks need pump-outs every 3–5 years. Ask for a record and inspection before buying rural properties.

5. Know the warning signs
Bad smells, lush grass over trenches, or soggy ground are all red flags. Surface effluent is not only illegal but a major public health risk.

The Bigger Picture

Our creeks, rivers, and coastal waters rely on every property doing its part. With more people living on acreages and off-grid blocks, wastewater system failures are becoming more common — but often go unnoticed until someone falls ill or council steps in.

If you’re unsure whether your system is working properly — or you’re buying a rural property — it’s worth getting a professional inspection. A well-designed, well-maintained system is essential for protecting your health, your land, and your local environment.

🚫 What NOT to Flush (and What to Do Instead)

Many common household items can have a significant negative impact on the environment when disposed of improperly. Wet wipes, for example, often block pipes and contribute microplastics to waterways, but reusable cloth wipes provide a sustainable alternative. Sanitary products, floss, and swabs don’t break down easily and can pollute water systems; choosing bamboo or organic cotton options helps reduce this impact. Harsh chemical cleaning products kill beneficial bacteria and contaminate water supplies, whereas natural alternatives like vinegar, castile soap, and plant-based scrubs are safer for both people and the planet. Medications flushed down drains can harm aquatic life and contribute to antibiotic resistance—returning unused medicines to local pharmacy take-back programs is a responsible choice. Cooking oils and grease can clog pipes and damage septic systems, but storing them for proper disposal or recycling prevents these issues. Lastly, microfibres from synthetic clothing pollute waterways, but using microfiber-catching devices like the Cora Ball or wash bags, and opting for natural fibre clothing, can significantly reduce this pollution. Adopting these eco-friendly alternatives helps protect our waterways and supports a healthier environment for everyone.

Understanding Nitrogen in On-Site Wastewater Management Systems (OSMS) in Northern Rivers, Australia

In on-site wastewater management systems (OSMS)—such as septic tanks, aerated wastewater treatment systems (AWTS), and reed bed systems—nitrogen is a key component of wastewater that must be managed properly to prevent environmental harm. Below, I’ll explain how nitrogen cycles through these systems and how it differs from agricultural nitrogen sources.

Nitrogen in On-Site Wastewater Management Systems

Household wastewater contains nitrogen from urine, feces, food waste, and detergents. When this wastewater is treated in an OSMS, nitrogen goes through several transformations:

  1. Ammonification (Organic Nitrogen → Ammonia/Ammonium)

    • Waste from toilets and kitchens contains organic nitrogen.

    • Microbes in septic tanks or treatment units break it down into ammonium (NH₄⁺).

  2. Nitrification (Ammonium → Nitrate)

    • In systems with aerobic treatment (like AWTS or sand filters), bacteria convert ammonium into nitrate (NO₃⁻), which is more mobile in soil.

  3. Denitrification (Nitrate → Nitrogen Gas)

    • In systems with anaerobic conditions (like wetlands or deep soil layers), bacteria convert nitrate into nitrogen gas (N₂), which escapes harmlessly into the atmosphere.

  4. Plant Uptake (in Land Application Areas)

    • If wastewater is dispersed via subsurface irrigation or an evapotranspiration area (ETA), plants and soil microbes can absorb and use some of the nitrogen before it reaches groundwater.

Nitrogen in Agricultural Systems

In contrast, nitrogen from farms comes from:

  • Animal waste (urine, manure, and decomposition of organic matter).

  • Fertilizers (synthetic or organic, such as urea and ammonium nitrate).

  • Crop residues breaking down into nitrogen.

Key Differences from OSMS:

The primary difference between OSMS and agricultural nitrogen management lies in scale and application. On-site wastewater systems manage nitrogen at the household level, processing human waste and food scraps in contained treatment units. These systems are designed to prevent direct pollution by using soil-based disposal and treatment methods, such as reed beds or subsurface irrigation. In contrast, agricultural nitrogen management occurs on a much larger scale, with farms applying manure and synthetic fertilizers directly to fields. This increases the risk of runoff into waterways and nitrogen leaching into groundwater.

Processing methods also differ significantly. Household OSMS rely on controlled treatment processes such as nitrification, denitrification, and plant uptake to reduce nitrogen impacts. Agricultural practices, however, involve direct land application of nitrogen-rich materials, often exceeding what crops can absorb, leading to nutrient loss and environmental pollution.

Additionally, OSMS are regulated per household, ensuring compliance with environmental standards, while agricultural nitrogen management is governed by broader land-use practices and fertilizer regulations. Due to the high nitrogen loads applied to farmland, the risk of pollution from agriculture is significantly greater than that of a properly managed OSMS.

How Farmers Can Work with the Nitrogen Cycle

Farmers can take several measures to manage nitrogen efficiently and reduce environmental impacts. Implementing cover cropping with legumes can naturally fix atmospheric nitrogen in the soil, reducing the need for synthetic fertilizers. Rotational grazing helps distribute manure evenly across fields, preventing excessive nitrogen buildup in one area. Using precision fertilization techniques, such as slow-release fertilizers and soil testing, ensures that crops receive the exact amount of nitrogen they need, minimizing excess runoff. Additionally, buffer strips and constructed wetlands can capture and process excess nitrogen before it reaches waterways, helping to protect local ecosystems. By aligning their practices with the natural nitrogen cycle, farmers can maintain productivity while reducing nitrogen pollution.

Why Nitrogen Management Matters for OSMS

If a septic system or land application area is poorly designed:

  • Excess nitrate can leach into groundwater, contaminating drinking water sources.

  • High nitrogen levels in soil and water can contribute to algal blooms in nearby rivers and lakes.

How to Reduce Nitrogen Pollution from OSMS:

  • Use advanced treatment (e.g., AWTS, reed beds, wetlands).

  • Design larger land application areas for better absorption.

  • Maintain the system properly to prevent septic failure and leaks.

While OSMS and farms both contribute nitrogen to the environment, the risk and scale of pollution from agriculture is much higher due to direct land application and runoff potential. Properly managed OSMS can significantly reduce nitrogen impacts at the household level, supporting healthier soils and waterways in Northern Rivers.

What is a wastewater management report?

A Wastewater Management Report is a technical document that outlines how sewage generated on a property will be managed, treated, and disposed of. It is an important aspect of On-site Sewage Management (OSSM) for locations that are not connected to centralised sewage services. The report is typically prepared by environmental health specialists and involves a careful consideration of various options and site features for managing on-site wastewater while ensuring the protection of public and environmental health.

Here are some key points about Wastewater Management Reports:

  1. Technical Nature: Wastewater Management Reports are technical documents that involve engineering and environmental health expertise. They provide details on the treatment and disposal methods for sewage on a specific site.

  2. On-site Sewage Management (OSSM): This term refers to the overall process of managing sewage generated on-site. The report is a key component of OSSM and helps in planning for the effective handling of wastewater.

  3. Development Consideration: For new construction projects, the need for a Wastewater Management Report may be indicated through communication from local authorities or may be identified during the development application (DA) process. It is an essential consideration for ensuring that proper sewage management is in place.

  4. Existing Residences and Commercial Premises: Existing properties may also require a Wastewater Management Report, especially if there are indications or issues with the current wastewater system. This need can arise after a local government inspection reveals faults or when the existing system is nearing the end of its design life.

  5. Government Regulations and Technological Advancements: Government regulations regarding wastewater management can become more stringent over time. Additionally, advancements in wastewater treatment technologies may make it more practical and cost-effective to upgrade or replace existing systems.

  6. Contacting Professionals: If there is uncertainty about whether a Wastewater Management Report is needed or if there are questions about development application requirements, individuals can contact experienced wastewater consultant, such as Byron Environmental Consulting, for guidance and assistance.

In summary, a Wastewater Management Report is a crucial document that addresses the effective handling of sewage on-site, considering both environmental and public health aspects. It is relevant for both new developments and existing properties, and seeking professional advice is recommended to ensure compliance with regulations, receive independent advice about the pros and cons of wastewater systems and the implementation of appropriate wastewater management solutions.
