Back in late August, just as the winter winds were drying out the last of the moisture from the Gold Coast hinterland, we received a call from a property owner named Dave. He had 10 acres tucked away near Guanaba Creek Road, right on the flank of Tamborine Mountain. It was beautiful country, but Dave was losing sleep. His house sat right at the top of a steep ridge, and looking down, all he could see was a literal wall of fuel.
The property was a classic example of what happens when the South East Queensland climate meets a few years of neglect. The bottom half of the block was choked with Lantana so thick you couldn't even poke a stick through it. Higher up, as the ground turned into a 45-degree scramble, Privet and massive clumps of Wild Tobacco had taken hold.
Dave knew that if a fire started in the valley below, it would roar up that slope like it was in a chimney. He’d tried to get a few blokes with slashers out there, but they’d take one look at the incline and the density of the scrub and tell him it was a "no-go" zone. That is where we come in. At ADS Forestry, we don't just work on the flat paddocks; we specialise in the bits other operators won't touch.
The Challenge: A Canyon of Fuel and 60-Degree Grades
When I first walked the site with Dave, the scale of the task was clear. This wasn't just a bit of weed removal. It was a full-scale restoration project. The Other Scrub/Weeds had created a continuous layer of fuel from the ground right up into the canopy of the native gums.
The biggest hurdle was the terrain. Parts of the gully dropped away at nearly 60 degrees. Conventional tractors or skid steers would have ended up at the bottom of the creek in about ten seconds flat. To make matters worse, the property was littered with old volcanic rocks from the mountain, hidden under years of leaf litter and Long Grass.
Dave’s main goal was simple: protect the house. He needed a defensible space and a clear perimeter. In Queensland, the Rural Fire Service always talks about "Inner Protection Zones," and Dave didn't have one. He had a powder keg. He also wanted to be able to actually walk his land again, rather than just gazing at a wall of green from his veranda.
Our Approach: Precision Forestry Mulching on the Edge
We decided the best tool for this job was our specialised steep terrain clearing equipment. Unlike a bulldozer that pushes dirt and creates big piles of debris that you then have to burn or haul away, our forestry mulching gear shreds everything where it stands.
We started at the top near the house to establish the most critical fire breaks first. This gave Dave immediate peace of mind. Our machines are designed with a low centre of gravity and high-traction tracks that allow us to bite into those steep slopes.
Working in September is always a bit of a race. The humidity is low, the westerly winds start picking up, and the vegetation is at its driest. We had to be incredibly careful with sparks, but that is the beauty of a mulcher. It doesn't leave huge piles of dead, dry brush sitting around for months. It turns the invasive woody weeds into a damp, thick layer of mulch that sits flat on the ground. This mulch actually helps retain soil moisture and prevents the very erosion that often happens when people clear steep hillsides the wrong way.
Dealing with the Heavy Hitters: Camphor and Lantana
As we moved down the slope, we hit the heavy stuff. There were several large Camphor Laurel trees that had been allowed to sap the nutrients from the soil for decades. These things are a nightmare for local biodiversity, and they drop thousands of seeds that just keep the cycle going.
Our mulching head made short work of the smaller Camphors, turning them into chips in seconds. For the bigger ones, we strategically thinned the canopy to allow light back down to the forest floor. This is a big part of paddock reclamation and forest management. If you don't let the sun in, the native grasses can't grow back to compete with the weeds.
The Lantana was the next big boss. In South East Queensland, if you give Lantana an inch, it’ll take a kilometre. It had formed a massive thicket about three metres high. Dealing with this on a 50-degree slope requires a bit of finesse. You can't just barge in. You have to work the machine methodically, Mulching from the top down to ensure the root balls are disturbed enough that they won't just' bounce back after the next rain.
Why Steep Slopes Require a Different Strategy
A lot of property owners in areas like the Scenic Rim or the Gold Coast Hinterland try to do this work themselves with a brush cutter or a chainsaw. I reckon that is a recipe for a broken back or worse. When you are on a slope that steep, gravity is always trying to pull you down.
When we operate on these inclines, we are focused on two things: operator safety and soil stability. If you scrape the ground bare with a bucket or a blade, the first summer storm will wash half your property down into the neighbour's yard. We leave the mulch behind as a protective "blanket." It slows down water runoff and gives the native seeds a chance to germinate.
By the third day on Dave's property, we had cleared a twenty-metre wide buffer zone all the way around his southern and western boundaries. We had also punched through a new access track down to the creek. Before we arrived, the only way to get to the bottom of the block was a dangerous scramble on all fours. Now, he could get a small 4WD or a quad bike down there to maintain the area.
The Transformation: From Fire Hazard to Hinterland Haven
By the end of the week, the transformation was fair dinkum incredible. What was once a scary, impenetrable mess of weeds was now an open, manageable park-like setting.
Dave came out on the final afternoon, and I reckon he looked ten years younger. He could actually see the view of the valley again. More importantly, he had a clear zone between the bush and his family home. The mulch layer was thick and tidy, looking almost like a landscaped garden bed rather than a cleared construction site.
We’d successfully managed to:
- Remove several tonnes of fuel load that would have accelerated any bushfire.
- Eradicate a massive seed bank of invasive weeds that were threatening the neighbouring properties.
- Open up access to the lower half of the property for future maintenance.
- Stabilise the steep banks using the mulched material to prevent erosion during the upcoming October storm season.
Local councils across South East Queensland are getting tighter on vegetation management, and Dave was happy to know he was now well within his rights for fire mitigation clearing. He didn't have to worry about the "fuel ladder" anymore, where fire climbs from the grass into the bushes and then into the crowns of the trees.
Advice for Owners of Overgrown Slopes
If you are looking at your own block and wondering where to start, my advice is simple: don't wait until the smoke is on the horizon. Most people wait until December when the fire danger is "Extreme," and by then, the ground is often too dry and the risk of starting a fire while trying to prevent one is too high.
Late winter and early spring are the best times to get stuck in. The ground is firm enough to support the machines, but there is usually still enough moisture in the mulch to help it settle and begin breaking down.
If you have a property in the Scenic Rim, Logan, or anywhere around Tamborine Mountain that looks like Dave’s did, give us a shout. We aren't afraid of a bit of a climb. We’ve built our reputation on doing the hard yards on the hillsides where others won't go. Whether it is a couple of acres of Lantana or a 20-acre block that needs a full fire management plan, we have the gear and the experience to handle it safely.
No worries if you aren't sure where to start. We can walk the property with you and figure out a plan that fits your budget and your goals for the land. There is no better feeling than knowing your home is safe and your land is finally working for you, not against you.
