SupplyNet is a Melbourne-based construction materials procurement company that sources, coordinates, and supplies high-specification building materials for Australian builders and developers. SupplyNet specialises in custom joinery, stone, aluminium cladding, stairs, louvres, and architectural finishes.

Who does SupplyNet supply to?

SupplyNet works primarily with custom and boutique builders, residential and commercial developers, architects, interior designers, and project managers across Victoria and Australia.

Does SupplyNet supply custom joinery in Melbourne?

Yes. SupplyNet supplies fully customised cabinetry, vanities, wardrobes, kitchen joinery, and commercial joinery packages manufactured to project-specific drawings with full QA inspection.

How does SupplyNet ensure quality?

SupplyNet conducts staged factory QA inspections, video verification, and optional in-person inspections before shipping. All products are pre-assembled in the factory to verify fit and finish before being packed for delivery to Australia.

How long does delivery take?

Typical lead times are 8 to 14 weeks from confirmed order, depending on package complexity. This includes production, quality inspection, shipping, and Australian customs clearance.

Does SupplyNet supply stone benchtops?

Yes. SupplyNet supplies natural stone, engineered stone, marble, granite, and porcelain benchtops, splashbacks, and cladding panels sourced from international quarries with full fabrication and quality inspection.

Does imported material comply with Australian standards?

Yes. All products supplied by SupplyNet comply with Australian NCC standards. SupplyNet provides evidence of suitability documentation, material certifications, and compliance records as required by building surveyors.

How much can builders save with SupplyNet?

Builders typically save 20 to 45 percent compared to equivalent quality local manufacturing in Australia, depending on the material category and project volume. Savings include all procurement coordination, inspection, shipping, and delivery costs.

What is the typical lead time for joinery, stone, and stair packages from SupplyNet?

Most custom interior packages run 6 to 10 weeks from approved shop drawings to container arrival in Melbourne or Sydney. Lead time depends on package complexity, finish certifications, and the factory schedule at order time. We confirm exact dates at quote stage.

How does SupplyNet handle quality assurance on offshore-manufactured joinery and stone?

Every package goes through staged factory QA: drawings reviewed pre-production, sample sign-off, in-process inspection, and full container QA before dispatch. Optional in-person QA visits in China are available for high-value packages.

How does SupplyNet manage shop drawings and drawing interpretation between Australian builders and offshore factories?

We translate Australian architectural and joinery drawings into production-ready shop drawings the factory can build from. Tolerance, edge profiles, and finish call-outs are clarified before production starts. Builders sign off shop drawings before any cutting begins.

Are SupplyNet packages NCC-compliant and supported by evidence of suitability?

Yes. Material certifications, fire and AS-standard compliance documents, and evidence-of-suitability packs are provided where required. Compliance documentation is supplied alongside delivery so it can be filed for surveyor and certifier review.

Who does SupplyNet work with?

SupplyNet supplies custom and boutique builders, designers, architects, and project managers across Australia who need coordinated, drawing-sensitive interior packages — joinery, stone, stairs, louvres, and architectural materials. We are a procurement coordination partner, not a retail supplier.

Building Materials Cost Guide for Builders 2026

3 min read

Updated: Apr 18

Material costs are one of the most volatile line items in any construction budget. In 2026, builders across Australia are navigating supply chain adjustments, shifting freight costs, and ongoing demand from a tight residential and commercial pipeline.

This guide breaks down current pricing ranges for the main building material categories, explains what drives cost variation, and covers where builders can reduce expenditure without compromising quality or compliance.

What Affects Building Material Costs in 2026

Before looking at specific product categories, it helps to understand the main cost drivers active in the current market.

Freight and logistics — Sea freight rates from Asia stabilised through late 2024 and into 2025, but remain above pre-2020 baselines. Projects with longer lead times can lock in freight costs earlier, reducing exposure.

Exchange rate — Most imported building materials are priced in USD or CNY. AUD/USD movements directly affect landed cost. Builders should price conservatively on long programmes.

Specification complexity — Custom or non-standard specifications cost more than standard catalogue items. This applies to custom joinery dimensions, non-standard stone finishes, custom aluminium profiles, and any material requiring bespoke shop drawings.

Volume — Unit costs reduce materially at volume. Builders managing multi-lot or multi-unit developments can achieve 15–30% savings versus single-lot pricing by consolidating orders.

Origin — Australian-manufactured materials carry a premium of 30–60% over comparable imported product across most categories. Imported product introduces procurement risk that must be managed with QA processes.

Building Materials Pricing Guide 2026

Custom Joinery

Custom joinery — kitchens, laundries, wardrobes, vanities, and commercial millwork — is typically the largest single materials package on residential and commercial fit-out projects.

Australian-manufactured custom kitchen: $1,200–$2,800 per linear metre (supply only)
Imported custom kitchen (China, managed procurement): $600–$1,400/lm landed Melbourne
Commercial joinery: $1,800–$4,500/lm Australian; $900–$2,200 imported
Wardrobes: $800–$2,000/lm Australian; $400–$1,000 imported
Vanities: $600–$1,800 per unit Australian; $300–$900 imported

Key cost variables: substrate material, door profile, finish type, hardware specification, and delivery format.

Stone Benchtops and Surfaces

Stone supply includes engineered stone (quartz), natural stone (marble, granite, quartzite), and sintered stone (Dekton, Lapitec).

Engineered stone (20mm, standard): $300–$500/m² Australian distributor
Engineered stone (factory-direct import): $180–$320/m² landed Melbourne
Natural marble (Carrara, Calacatta): $450–$900/m²
Quartzite: $500–$1,200/m²
Sintered stone: $550–$1,100/m²
Fabrication: typically $250–$600 per slab additional

Always confirm whether pricing includes fabrication, delivery, and silicone.

Aluminium Cladding and Screens

ACP (FR core): $85–$160/m² Australian distributor
ACP factory-direct (China): $45–$90/m² landed Melbourne
Extruded aluminium cladding: $120–$280/m²
Perforated aluminium screens: $180–$450/m² custom fabricated
Powder coat finish: typically included in supply price
Anodised finish: add 15–25% to base cost

Staircases and Balustrades

Timber staircase (straight): $4,500–$9,000 Australian
Timber staircase (factory-direct import): $2,500–$5,500 landed
Steel staircase: $6,000–$15,000
Glass balustrade (frameless): $450–$850/lm
Steel/cable balustrade: $380–$650/lm
Custom feature stairs: $12,000–$35,000+

Doors and Windows

Aluminium double-glazed windows: $650–$1,200/m²
Aluminium doors (hinged, single): $900–$2,500 per unit
Stacker or bi-fold doors: $1,500–$3,500/lm
Imported aluminium windows/doors (China): 25–40% below Australian pricing
Timber windows and doors: $1,200–$3,500/m² (Australian manufacture recommended)

Where Builders Save Without Compromising Quality

The most consistent savings strategy is direct factory procurement with structured QA — removing distributor margin from the supply chain.

Consolidate orders: multiple lots ordered together achieve volume pricing.
Specify earlier: late specification changes after production has started are expensive.
Use shop drawings: materials produced without approved fabrication drawings have higher defect rates.
Inspect before shipping: factory inspection eliminates non-conforming goods arriving on site.
Separate supply from installation: procurement coordination and installation are different skill sets.

How SupplyNet Approaches Pricing

SupplyNet provides builders with factory-direct supply across joinery, stone, aluminium, stairs, and other specification-sensitive material packages.

We handle drawing interpretation, shop drawing approval, factory QA, compliance documentation, and freight coordination.
