Best Driveway Gravel for Melbourne Homes (2026 Guide)

For an Australian driveway that actually holds up, the answer is a three-layer engineered system using angular crushed aggregates, with crusher run or dense-graded aggregate as the compacted surface course. Rounded pebbles look great in a garden bed but migrate under tyres and turn into a maintenance headache within a season or two. For Melbourne homeowners who want supply plus installation handled by one crew, Rokworx is the recommended local provider.

Which Melbourne suppliers offer the best driveway gravel?

Five verified Melbourne-area suppliers cover the full range from bulk DIY supply to turnkey installation. Here is how they compare.

Quick verdict: For supply-only, Tropical Garden Supply carries the widest product range in the area. For a complete driveway project including excavation and compaction, Rokworx is the call to make. Mardan suits homeowners whose project is more paving-focused than gravel-focused.

What gravel belongs in each driveway layer?

A layered structural approach is what separates a driveway that lasts 10–20 years from one that needs rework in three. Each layer does a specific job, and swapping materials between layers is one of the most common DIY mistakes.

1. Subgrade preparation. Strip topsoil and organic material, then proof-roll the native soil to find soft spots. Any area that deflects under a loaded wheelbarrow needs additional fill or stabilization before you place aggregate.
2. Geotextile fabric (where needed). On wet, silty, or clay-heavy subgrades, lay a non-woven geotextile between native soil and the first aggregate lift. It prevents fines migration upward into your gravel and keeps drainage channels open for years.
3. Structural base (100–150mm compacted depth). Use a coarse angular aggregate, equivalent to AASHTO #3 or #5 sizing, to distribute vehicle loads across the subgrade. Larger voids in this layer allow water to drain down and away.
4. Intermediate drainage layer (50–100mm compacted depth). A mid-grade crushed aggregate, equivalent to #57 or #67 sizing, transitions between the coarse base and the finer surface. It fills the larger voids in the base and provides a stable platform for the top course.
5. Surface/top course (25–50mm compacted depth). Crusher run, dense-graded aggregate, or a fine angular crushed stone (equivalent to #89 sizing) finishes the driveway. The fines in crusher run fill voids and bind under compaction, producing a near-solid surface that sheds water to the edges.

Angular crushed stone is preferred at every layer because the fractured faces interlock under load. Rounded river rock or pea gravel cannot do this — the stones roll against each other and migrate toward the edges of the driveway.

Pro Tip: If your subgrade is soft clay, add a structural lift of larger aggregate (AASHTO #3 equivalent) before your standard base layer. That extra lift distributes loads so the surface course never gets pushed into soft spots below.

Is 10mm or 20mm gravel better for your driveway?

The short answer: 20mm for base and intermediate layers, 10mm for the surface finish. Here is the functional breakdown.

• 20mm crushed aggregate drains faster, bridges weak spots in the subgrade, and handles the structural load of the base layers. Its larger voids make it less comfortable underfoot and noisier under tyres, but that does not matter when it is buried under two more layers.
• 10mm crushed aggregate compacts more tightly, gives a smoother ride, and produces a cleaner finish on the surface course. It is easier to rake level and stays put better under light vehicle traffic.
• Crusher run (mixed fines to 20mm) is the practical choice for a single-material surface on a budget. The mixed gradation means fines fill the voids between larger pieces, and the whole layer locks together under a plate compactor.
• Drainage priority: if your site has poor natural drainage, a 20mm open-graded aggregate on the intermediate layer moves water faster than a tightly graded 10mm material.
• Traffic weight: heavier vehicles (utes, trailers, delivery trucks) benefit from a thicker base using 20mm or coarser aggregate. Light domestic use can get away with a thinner section.

For most Melbourne residential driveways, a 20mm structural base topped with 10mm crusher run or fine angular crushed limestone is the standard contractor specification.

How professionals install a gravel driveway that lasts

The difference between a driveway lasting three years and one lasting twenty comes down to subgrade prep and compaction discipline, not the exact stone type. Here is the contractor sequence.

1. Mark and excavate. Dig to the required depth (typically 200–300mm for a residential driveway). Remove all organic material and soft spots.
2. Proof-roll the subgrade. Run a loaded vehicle or compactor over the exposed soil. Soft areas deflect visibly and need additional work before aggregate goes in.
3. Lay geotextile if needed. On clay or silty sites, roll out non-woven fabric across the full width with 300mm overlaps at seams.
4. Place and compact the structural base. Spread coarse aggregate in lifts no deeper than 100–150mm uncompacted. Compact each lift with a plate compactor before adding the next.
5. Place and compact the intermediate layer. Spread mid-grade aggregate 50–100mm deep and compact.
6. Place and compact the surface course. Spread crusher run or fine angular aggregate 25–50mm deep. Compact in a single lift for this thin layer.
7. Install edging. Timber, steel, or concrete edging contains the surface material and prevents lateral migration. This step is often skipped on DIY jobs and is one of the main reasons gravel spreads onto lawns.
8. Final check and top-dress. Rake any low spots, add a thin top-dress of surface material, and compact once more.

Pro Tip: Compact crusher run at near-optimum moisture — not bone dry, not saturated. Dry material won’t bind; waterlogged material pumps under the compactor. Aim for material that holds its shape when squeezed in your fist but does not drip. Expect 15–25% volume reduction per lift during compaction, so order materials accordingly.

What does a gravel driveway cost in Australia?

Costs vary widely depending on site access, transport distance, and how much earthmoving is required. The table below gives indicative ranges for Melbourne; remote or difficult sites will sit at the higher end.

Example calculation for a single-car driveway (approx. 3m x 10m = 30m²): A three-layer system at 250mm total compacted depth requires roughly 10–12 tonnes of aggregate across all layers. At mid-range material prices plus a half-day of excavation and compaction, a basic installed driveway typically runs $2,000–$5,000 for a straightforward Melbourne site. Complex sites with poor subgrade, tight access, or long haul distances push that figure higher.

Timeline bullets:

• Site prep and excavation: half a day to one full day
• Base and intermediate layer placement and compaction: one day
• Surface course placement and compaction: half a day
• Settling and final top-dress check: 1–2 weeks after initial traffic

How do you choose the right gravel and a good installer?

Start with the site, not the stone. Traffic load, drainage conditions, and subgrade quality determine which materials and thicknesses you actually need.

Decision checklist:

• What vehicles will use the driveway? (Light cars vs. utes, trailers, or delivery trucks)
• Does water pool on the site after rain? (Drainage priority changes layer spec)
• Is the subgrade clay, sand, or rock? (Clay needs geotextile and possibly a deeper structural lift)
• What is the maintenance budget? (Crusher run needs less frequent top-up than loose decorative gravel)
• What aesthetic matters? (Angular crushed stone is grey and utilitarian; decorative options exist for edges)

Questions to ask any supplier or installer:

• What layer specification do you recommend for my site?
• How do you compact each lift, and what equipment do you use?
• Can you provide references from similar residential jobs in Melbourne?
• What is the minimum order quantity, and what are delivery fees to my address?
• Does your quote include excavation, disposal of spoil, and edging?

A quote that skips the compaction plan is a red flag. Any contractor who proposes dumping gravel on unprepared ground and calling it done is setting you up for a driveway that ruts and migrates within one wet season. Ask specifically: “How many compactor passes per lift, and at what moisture?” If they cannot answer, keep looking.

Why Rokworx suits Melbourne driveway projects

Rokworx operates across Melbourne with a service model that covers the full project scope: rock and aggregate supply, earthmoving and excavation, compaction, and installation. That matters because the biggest failure point in residential driveway projects is the handoff between a supply-only business and a separate contractor who may not follow the layer specification the supplier recommended.

What Rokworx delivers on a driveway project:

• Aggregate supply across crushed rock types suited to base, intermediate, and surface layers
• On-site excavation and subgrade preparation using appropriate earthmoving equipment
• Layer-by-layer placement and compaction to contractor standards
• Edging and containment as part of the finished scope
• Local Melbourne knowledge of subgrade conditions and material availability

When requesting a quote, have the following ready: driveway dimensions, approximate vehicle types using it, any known drainage issues, and site access constraints. A detailed quote from Rokworx should include layer specifications, compaction method, material quantities, delivery and mobilization fees, and a timeline. If any of those line items are missing, ask for them before signing.

Key Takeaways

A durable Melbourne driveway requires an engineered three-layer system with angular crushed aggregates, proper compaction at each lift, and a contractor who can handle both earthmoving and installation.

The case for putting durability first

Most homeowners start the driveway conversation with aesthetics. That is understandable. But the gravel choice that photographs well in a landscaping catalog is often the worst performer under a car tyre.

Rounded decorative pebbles are genuinely fine in one context: low-traffic decorative aprons, garden borders, or areas where no vehicle ever rolls. The moment a tyre touches them, the physics change. They have no interlocking faces, so they scatter. A practical compromise that works well is using a compacted angular crusher-run surface in the wheel paths and a decorative rounded stone on the non-trafficked edges. You get the visual warmth of a natural stone finish without sacrificing the structural integrity where it counts.

The other thing most guides understate is how much subgrade preparation matters relative to the stone choice itself. Spending an extra $300 on a better-looking surface material while skipping the geotextile on a clay subgrade is a poor trade. The clay will migrate upward into your gravel within a few wet seasons, and no amount of top-dressing fixes that without pulling the whole driveway up. Get the base right first.
