It's one of the best things you can add to a residential property, especially if you've got kids or love a casual game on weekends.
But before you start measuring out your yard and picking out a hoop, there are a few things you need to think through. Skip these steps and you could end up with a court that cracks after a wet winter, drains poorly, or doesn't meet your local council's requirements.
Here's what to sort out before anything goes into the ground.
Get Your Measurements Right Before Anything Else
This Decision Affects Everything, Performance, Cost, and Longevity
Poor Drainage Is the Number One Cause of Premature Surface Failure
Don't Skip This Step, It Can Derail the Whole Project
The Court Itself Is Only Part of the Cost
All Surfaces Need Some Upkeep, Know What You're Committing To
The Right Contractor Makes a Significant Difference
A full NBA court is 28 by 15 metres, that's not happening in most backyards. But you don't need a full court to have something genuinely useful.
A half-court setup can work well in a space as small as 9 by 7.5 metres. A third-court is even smaller and still gives you room to shoot, dribble, and practise properly.
The key is being realistic about what fits. Measure your available space properly, not just the open grass area, but accounting for fencing setbacks, garden beds, and any overhead obstructions like power lines or large trees. Trying to squeeze a court into a space that's too tight usually creates problems later.
This is probably the most important call you'll make. The surface you choose determines how the court plays, how long it lasts, and what kind of maintenance it needs.
Asphalt is one of the most popular choices for residential basketball courts in Australia, and for good reason. It's durable, handles Australian weather well, and gives you a consistent playing surface that doesn't deteriorate quickly. A properly laid asphalt court can last 20 or more years with reasonable maintenance. It's also more affordable than some alternatives, which matters when you're talking about a decent-sized slab.
Concrete is another solid option. It's extremely hard-wearing, but it can be tough on joints, especially if you're playing regularly. Concrete also tends to cost more upfront.
Modular sports tiles are popular for their cushioning and colour options, but they sit on top of a base surface, so you still need a properly prepared sub-base.
Whatever material you go with, the quality of the sub-base preparation matters just as much as the top layer. A poorly prepared base will cause problems no matter what you put on top.
Water is the enemy of any outdoor hardscape. If your court doesn't drain properly, you'll end up with pooling water, surface erosion, and eventually, cracking.
Before installation, you need to understand how water currently moves across your yard. A good installer will assess the natural slope of your land and factor in drainage requirements as part of the design. Courts are typically built with a slight gradient, usually around 1%, so water runs off the playing surface rather than sitting on it.
If your yard has existing drainage issues, those need to be addressed before the court goes in, not after.
In most parts of Australia, installing a hardscape like a basketball court requires some form of council approval. The specifics vary by state and local council, but you'll typically need to consider:
It's worth calling your local council early in the planning process, even if just to confirm what approvals are needed. Finding out mid-construction that you need a permit you don't have is not a situation you want to be in.
A lot of people budget for the surface and forget everything else. Here's what can add up:
Get a full scope of works from your installer before signing anything, so you're not hit with surprises halfway through.
No outdoor surface is completely maintenance-free, and a backyard basketball court is no different.
Asphalt courts should be inspected periodically for cracking, especially after harsh summers or cold snaps. Small cracks caught early are easy to repair; left too long, they grow and let water in, which speeds up deterioration. A light clean to remove leaf litter and debris also helps preserve the surface.
Line markings do fade over time and will eventually need repainting, typically every five to eight years, depending on use and UV exposure.
Factoring in maintenance from the start means you won't be caught off guard when minor repairs come up down the track.

This one matters more than people expect. A court that looks good on day one but develops problems within a few years usually comes down to poor installation, specifically, inadequate base preparation, incorrect gradients, or the wrong materials for the site conditions.
When choosing a contractor, look for someone who has experience specifically with sports surfaces and outdoor hardscapes, not just general concreting or paving. Ask to see examples of past work. Ask about the base preparation process. If a quote seems unusually low, it's worth asking what's been left out.
A well-installed asphalt basketball court is a long-term investment. Getting the installation right the first time saves money over the life of the court.
