Colorbond Driveway Gates: A Sydney Buyer's Guide
Updated: Sep 30
On most Sydney properties the driveway gate is the most expensive few metres of the fence, and it is also the part most likely to cause grief a few years later. A fence panel either stands up or it doesn't. A gate has to move, thousands of times, while carrying its own weight out to one side. Get the opening width, the way it opens and the posts right at the start, and the gate will still be closing sweetly long after the rest of the fence has weathered.
Start with the opening, not the gate
The most common mistake is ordering a gate to the width of the driveway. What matters is the clear opening between the finished faces of the two gate posts once they are in and clad. Post size, cladding and the hinge and latch gaps all eat into that measurement, so a gate ordered to the slab width will not fit, and one ordered without allowing for hardware will bind on the first hot day.
Measure at the height the gate will actually sit, not down at ground level. Brick piers, retaining walls and driveway kerbs are rarely as parallel as they look. If the opening narrows towards the top, the narrowest point is the one to work from.
Sliding or swinging: which suits your driveway
Swing gates
A swinging gate is simpler, cheaper to build and easier to automate later, but it needs clear space to swing through. Opening inwards means the arc has to be free of the parked car, the bins and the garden bed, and the ground has to be reasonably level across that arc. A gate that clears the surface when closed can drag halfway through its swing on a steep crossfall. Opening outwards over a footpath is generally not acceptable and can breach council controls, so don't plan around it without checking first.
Sliding gates
A slider solves the arc problem and suits short driveways and sloping sites, but it needs somewhere to go. A tracked gate needs a clear, straight run along the fence line roughly as long as the gate itself, plus a track that gets kept free of grit and leaves. A cantilever gate carries itself on rollers set back behind the opening, which avoids the track but needs even more run-back and a heavier post arrangement. Either way, walk the fence line before you decide and see what is actually in the way: the meter box, a garden tap, a tree, a step in the retaining wall.
Single leaf or double?
Wide openings are usually hung as a pair. Two leaves are lighter individually, load each post less, and are easier to handle — and one leaf can be opened on its own for a wheelie bin or the mower. The trade-off is a drop bolt in the middle, two hinge sets to keep adjusted, and two leaves that have to meet neatly on a surface that may not be flat. A single leaf across a wide opening is a lot of cantilevered weight on one post. It can be done, but the post and footing have to be sized for that load rather than matched to the fence.
Work out the width from the vehicle, not the gap
Before settling on a size, think about how the car actually arrives. Turning in from a narrow street, off a busy road, or across a footpath with cars parked either side needs more room than a straight run-in. Measure your widest vehicle across the mirrors and allow clearance both sides, then add more if you tow a trailer or a boat, or if the driveway bends immediately behind the gate. Widening the opening while the posts are still going in costs very little. Rebuilding a pier afterwards does not.
Posts and footings do the real work
A Colorbond gate frame is light, but everything it weighs hangs off one post. Gate posts are heavier in section than the fence posts either side of them, and they go deeper, in a larger concrete footing. On a double gate, both posts carry that load. Where the gate hangs off a brick pier instead of a steel post, the pier and its footing have to be sound and the fixings suited to the masonry — a pier built as a decorative end to a fence is not always built to hold a gate.

Footings given time to cure before the gate is hung and loaded
Hinges with enough adjustment left in them to take up the small amount of movement every gate sees
A latch and drop bolt that still line up after the first wet season
Plan for automation before the concrete goes down
Most people who automate a driveway gate do it after the gate is installed, and most of them wish they had run the conduit first. If there is any chance of a motor later, put spare conduit under the driveway and out to both posts while the ground is open, and leave a draw wire in it. Talk to a licensed electrician about the supply, and have the gate built with automation in mind — frames, hinges and posts for a motorised gate are specified differently from a hand-operated one. Automatic gates also carry real safety obligations around entrapment and crushing, so use an installer who works to the current Australian Standards and can explain how your installation meets them.
Where the fence meets the gate
A driveway gate reads as part of the fence, so the details either side matter as much as the gate itself. Matching the infill profile and colour is the obvious part — our overview of Colorbond fencing in Sydney covers the range. Less obvious is the ground line. Driveways are laid with a crossfall so water runs off, which means a closed gate sits over sloping ground. Raking the bottom of the leaf to follow that fall looks deliberate; leaving a wedge-shaped gap does not. On a genuinely steep site the same stepped-versus-raked decision applies to the gate as to the fence, and we go through it in detail in our guide to Colorbond fencing on a sloping block.
Council, height and visibility
Front fences and gates are more regulated than side and rear boundaries. Height limits, setbacks, how much of the frontage can be solid, and sight lines for vehicles crossing the footpath all vary between councils, and heritage or conservation-area controls can override the general rules entirely. Some work is exempt development and some needs approval. Check your own council's controls and the NSW Planning Portal before you commit to a height or a solid design, and see our guide to council approval for fences in Sydney for how to work out which applies to you.
Frequently asked questions
Is a sliding gate more expensive than a swinging gate?
Usually, yes — there is more hardware, more structure and more setting out involved, and a cantilever slider more again. But the comparison worth making isn't sticker price, it's whether a swing gate will work on your driveway at all. Money spent on a slider that suits the site beats money spent on a swing gate that fouls the car.
Can I put a Colorbond gate in an existing brick opening?
Often, yes. It comes down to whether the piers are sound, whether their footings can take the load, and whether the opening is square and consistent in width from bottom to top. That is a look-and-measure job rather than something anyone should quote off a photo.
How wide can a single Colorbond gate leaf be?
There is a practical limit set by weight and leverage rather than one universal number, and it shifts with the frame, the infill height and the post. Past a certain width, a pair of leaves or a slider is the sensible answer. A fencer can tell you where that line sits for your particular opening.
Do driveway gates need a motor to be worth having?
No. Plenty of hand-operated gates get used happily for years, especially on short driveways where you're out of the car anyway. Automation earns its keep on long driveways, busy roads, and anywhere you'd otherwise be getting out in the rain twice a day.
Will a new gate match my existing Colorbond fence?
Colour ranges are consistent, but an existing fence has weathered and older profiles are sometimes superseded. Bring the colour name if you have it. Otherwise a fencer can usually identify the colour and profile on site and tell you honestly how close the match will be.
Getting it measured properly
