Most monkey bar assembly guides stop at "follow the instructions". This one goes further - because placement, anchoring, and timber care are the three things that determine whether your setup feels rock-solid for years or starts causing headaches after the first wet season.
This guide covers the full installation process for your monkey bars - where to position them, how to choose the right anchor for your soil type, how to protect the timber from the ground up, and what to check each season to keep everything safe. Australian backyards vary enormously, and the decisions you make during installation make a bigger difference than most people realise.
PLACEMENT
Where to Position Monkey Bars in Your Backyard
Before you dig a single hole or drive a single stake, walk your yard and check these clearances. Getting placement wrong means moving everything later - and that's no fun with a fully assembled frame.
Safety Clearances
You need a minimum of 2 metres of clear space in all directions from the monkey bars frame. That's front, back, and both sides. This is the fall zone - if a child slips, you want them landing on soft ground, not garden edging or the corner of a raised bed.
Overhead clearance matters too. A minimum 6 metres from ground level to any overhead obstacle - that includes power lines, tree branches, clotheslines, or the eaves of a shed. Kids don't just swing from monkey bars, they climb on top of them. Plan for that.
Ground Conditions
Level ground isn't optional. Even a slight slope puts uneven load on the frame and makes one side work harder than the other. Over time, that contributes to movement and loosening of anchor points. If your yard slopes, you'll need to either level the site or build up the low side with compacted soil or pavers before anchoring.
Avoid placing monkey bars directly under large trees. Yes, shade sounds appealing - but you'll be dealing with sap drips, leaf litter, and branches that drop in storms. Tree roots also create uneven ground underneath, making it harder to achieve a stable base. A few metres away from the canopy is fine. Directly underneath is asking for maintenance headaches.
Sun Exposure
Timber stays cooler than metal monkey bars in the Australian sun, but direct afternoon sun in summer still matters. If your monkey bars will cop full western sun from 2pm onwards, consider whether that's where your kids actually want to play in January. Morning sun and dappled afternoon shade is the sweet spot for year-round use.
Before You Dig: Call 1100 (Dial Before You Dig) before any ground penetration. This free service locates underground power, gas, water, and telecommunications lines on your property. It's a legal requirement in Australia - and it could save you from a very expensive accident.
UNDERSTANDING THE SWAY
Why Monkey Bars Move - And How to Fix It
Let's address this directly because it's the most common question we get about monkey bars: why do they sway, and is that normal?
Some flex in outdoor play equipment is expected - timber and joints move slightly under dynamic load. That's different from noticeable swaying or rocking when a child swings from rung to rung. The latter almost always traces back to anchoring.
What Causes Movement
The anchor plates included with monkey bars work well in firm, compacted soil. But Australian backyards vary enormously. Sandy coastal soil, high-clay soil that expands and contracts with moisture, and soft or waterlogged ground all reduce the holding power of basic ground stakes.
If you've followed the assembly instructions and the frame still moves more than feels right, the issue isn't the equipment - it's that the anchoring method doesn't suit your specific ground conditions.
This isn't about doing anything wrong. It's about matching the anchor type to what's actually happening below the surface of your yard.
ANCHORING METHODS
The Supplied Anchors - and When You Need More
Your monkey bars come with metal anchor plates (part D in the assembly instructions - six sets in total, two plates per post base). These bolt directly to the bottom of each post and drive into the ground to hold the frame in place. For firm, compacted soil they do a reasonable job.
But Australian backyards are not all firm, compacted soil.
Sandy coastal ground, high-clay soil that swells and shrinks with moisture, and soft or waterlogged yards all reduce the holding power of flat ground stakes significantly. If your soil doesn't grip the plates firmly, the frame will move - and no amount of re-tightening will fix that. You need an anchor type that suits what's actually in the ground beneath your yard.
Screw-In Ground Anchors
These spiral into the ground like a large corkscrew and provide much better hold than flat plates in most soil types. They're removable if you move house and work well in compact clay, loamy soil, and most suburban backyards with established lawns. Available at Bunnings in various lengths.
Best for: Most suburban backyards with firm to medium soil.
Surface Plate Anchors
Rather than penetrating the ground, these bolt through a timber base frame or concrete pad. You can build a simple base from treated pine sleepers, bolt the monkey bars frame down, and let the weight and surface area do the work. Good option if you can't dig deep or your soil is unreliable.
Best for: Soft or sandy soil, high water tables, or where digging isn't practical.
Concrete Footings
The most permanent option - and the right choice for very sandy coastal soil or yards that stay wet. Dig a hole at each post location, set a post stirrup into the wet concrete at the correct height, and allow it to cure fully before attaching the frame. The timber posts then sit in the stirrups above ground level - never in the concrete itself. This is important: concreting timber posts directly into footings traps moisture against the end grain and causes exactly the kind of rot you're trying to prevent. The concrete anchors the stirrup. The stirrup holds the post. The post stays dry.
Best for: Coastal properties, unstable or waterlogged ground, permanent installations.
Not sure which anchor suits your soil? The Bunnings trade desk is a practical first stop. Take a photo of your backyard and explain the soil conditions - they can recommend an anchor type based on what actually works in your area. It's free advice and worth the trip before you start digging.
TIMBER CARE
Ground Contact: Why It Matters More Than You'd Expect
Our monkey bars use untreated timber. That's a deliberate choice - chemical timber treatments involve compounds that aren't appropriate for play equipment where kids are in direct contact with the wood. It's the right call for safety.
But it does mean ground contact needs more thought than it would with treated pine. Untreated timber left in direct contact with soil will absorb moisture, and once that starts it doesn't stop. Moisture wicks up into the end grain, the timber stays damp, and decay works from the inside out. You won't see the damage until it's already significant.
This isn't a reason for concern - it's a reason to install it correctly from the start.
Post Stirrups: The Simple Fix
Post stirrups - also called post anchors or post shoes - lift the base of each timber post clear of the ground. The air gap this creates allows circulation underneath and stops moisture from wicking into the end grain. For untreated timber, this isn't optional. It's the single most important thing you can do to protect your investment.
They're available at Bunnings in screw-in, drive-in, and concrete-set styles. Match the stirrup type to your anchoring method - screw-in stirrups work with ground anchors, and if you're pouring concrete footings, use stirrups specifically designed to be set into wet concrete. Either way, the principle is the same: the stirrup goes into or onto the ground, and the timber post sits in the stirrup - never touching soil or concrete directly.
Combined with the right anchoring method for your soil type, post stirrups keep untreated timber off the ground, off the moisture, and in good shape for years.
Ground creep to watch for: Even with stirrups installed, soil and mulch can build up around post bases over time - especially near garden beds. Check every few months and clear any buildup away from the post bases. It takes two minutes and keeps the air gap doing its job.
ASSEMBLY PROCESS
Tools, Prep, and How to Assemble Monkey Bars
Assembly itself is straightforward if you prepare properly. Rushing this stage is how bolts get cross-threaded and frames end up slightly out of square.
What You'll Need
- Spirit level - a long one, at least 1200mm
- Post hole digger or star picket driver (depending on anchor type)
- Socket set - check the assembly instructions for specific sizes
- Tape measure
- Second adult - monkey bars aren't a one-person job
- Tarp or drop sheet to lay components on
Before You Start
Lay all components out on a tarp or soft surface. Check everything against the parts list in the instructions. It's much easier to identify a missing bolt now than halfway through assembly.
Assemble the frame loosely at first. Finger-tighten all bolts but don't fully tighten anything until the entire frame is together and you've checked it's level and square. This makes alignment much easier and prevents you from having to loosen everything to correct a wonky corner.
Assembly Order
Follow the instructions included with your specific model. Generally, you'll build the two end frames first, stand them upright, then connect them with the crossbars and rungs.
Once the frame is fully assembled and sitting level, go around and tighten every bolt properly. Use a socket wrench, not a screwdriver. Check each connection twice.
Then anchor. Test the frame for movement before you let kids use it.

ONGOING CARE
Seasonal Maintenance Checklist for Outdoor Monkey Bars
Monkey bars aren't fit-and-forget. A quick seasonal check keeps everything safe and extends the life of the equipment significantly.
Spring Check (Before School Holidays)
September or early October is the ideal time for this - before the kids are home all day and using the equipment constantly.
- Walk around the frame and tighten every bolt and connection
- Check all timber components for cracks, splits, or splintering - sand down any rough spots
- Test each ground anchor is still firm - grab the frame and try to rock it
- Inspect any ropes, chains, or grip surfaces for wear
- Clear any soil, mulch, or leaf litter that's built up around the base of posts
Timber Treatment
Apply a timber treatment (oil, stain, or paint) every 2-3 years. If you're within 5km of the coast, do it annually - salt air accelerates wear.
This isn't cosmetic. Untreated timber particularly benefits from a protective surface coating, especially on horizontal surfaces where water can pool. Our full painting, installation and maintenance guide covers the exact products and process.
Ground Creep
Over time, soil and organic matter can build up around the base of timber posts - especially if you've got garden beds nearby or use mulch. This ground creep brings moisture back into contact with the timber, exactly what you're trying to avoid.
Every few months, pull back any buildup and keep a clear gap around each post base. Small effort, big difference.
FINAL THOUGHTS
Get the Anchoring Right, Everything Else Follows
If there's one thing to take from this guide, it's this: the anchoring method matters more than anything else for how stable your monkey bars feel.
The included anchor plates work well in the right conditions. But if your soil is sandy, soft, or prone to moisture, don't fight it - choose an anchor type that suits what you're working with. And regardless of which anchoring method you go with, post stirrups keep the timber posts clear of the ground. For untreated timber that's not a nice-to-have, it's essential.
The Bunnings trade desk can point you in the right direction based on your specific yard. Call 1100 before you dig. Do a spring check each year. Those three habits keep the equipment safe and the timber in good shape for the long run.

Frequently Asked Questions
Do monkey bars need to be concreted in?
Not directly. If you choose concrete footings, post stirrups should be set into the wet concrete at each post location - the timber posts then sit in the stirrups above ground level, never embedded in the concrete itself. Concreting timber posts directly into footings traps moisture against the end grain and causes rot. Most backyards don't need concrete footings at all - screw-in ground anchors or surface plate anchors work well in most Australian soil types.
How do I stop my monkey bars from swaying?
Swaying almost always comes down to anchoring. If the included anchor plates aren't holding firm in your soil type, upgrade to screw-in ground anchors for better grip, or switch to surface plate anchors or concrete footings with post stirrups. Also check that the ground is level - even a slight slope puts uneven load on the frame and contributes to movement over time.
What clearance do you need around monkey bars?
You need a minimum 2 metres of clear space in all directions from the frame - that's the fall zone. Overhead, maintain at least 6 metres clearance from ground level to any obstacle including power lines, tree branches, or structures. Always call 1100 (Dial Before You Dig) before any ground penetration to locate underground services.
Should timber monkey bars touch the ground?
No - and this is especially important for untreated timber. Our monkey bars use untreated timber for safety reasons, which means direct ground contact will cause moisture damage faster than treated pine would. Use post stirrups to lift each timber post clear of the ground and create an air gap. This applies regardless of your anchoring method - including concrete footings, where the stirrup sets into the concrete and the post sits in the stirrup above ground level.
How often should I check the bolts on outdoor monkey bars?
Check all bolts and connections at least once a year - spring before the school holidays is the ideal time. If your kids use the equipment heavily or you're in a coastal area where salt air affects hardware, check every six months. Walk around the frame with a socket wrench and tighten anything that's loosened - it takes 10 minutes and keeps everything safe.
Can you install monkey bars on a slope?
You need level ground for safe installation. If your yard slopes, either level the site before installing or build up the low side with compacted soil or pavers. Installing on a slope puts uneven load on the frame, makes one side work harder than the other, and contributes to loosening and movement over time. It's worth doing the prep work to get it level.
