Supply Chain Dashboard

The Supply Chain Dashboard has been developed by DTF and provides users with an interactive tool for assessing supply, demand and cost for critical extractive materials and steel products.

The Dashboard is intended to enable government and industry to identify construction material requirements and potential risks to project delivery. By doing so, it assists industry parties in taking early action to mitigate these risks.

All data within the Dashboard is publicly available, apart from IA data on demand for materials required on infrastructure projects.

Victorian major public infrastructure information provided to IA for the purposes of modelling is based on Budget Paper 4.

Demand data within the Dashboard includes modelled data on the State of Victoria’s current (as at Budget 2026-27) and recently completed major project infrastructure pipeline based on data developed by Infrastructure Australia (IA).
Projects are only included if Total Estimated Investment (TEI), start date and end date are available. 'Major’ projects are considered projects with a TEI of $100 million or above. Historic projects are included up to approximately a decade prior, with the cost defined at completion, subject to change.

Estimates are subject to variation and will change based on updated reference project costs and new projects being added into the pipeline.

Demand volumes are calculated based on top-down splits of total cost into standardised resource classes, based on project type and a range of assumptions. This methodology is designed to provide a market aggregate perspective of demand, rather than a project-by-project view.

Data should be considered indicative only and is intended to help inform decisions on planning and budgeting.

Supply chain information is based on public infrastructure projects unless explicitly referencing both private and public sectors.

The Dashboard comprises six main sections:

1. Summary – this section provides a summary of key data from throughout the Dashboard. It also includes contextual data such as Victorian construction activity and the Global Supply Chain Pressure Index.
2. Materials – this section provides a detailed illustration of demand for each material covered in the Dashboard, and a rating based on a five-year historical average of demand from the Victorian major projects pipeline. It also includes information on material costs and supply, where available.
3. Public projects – this section provides an illustration of the Victorian Public Infrastructure projects that generate demand for key materials, and the combined material demand over time. There is also a breakdown of the proportion of materials required to deliver different project types.
4. All sectors – this section includes data on private sector construction demand. It allows users to explore broader industry demand and the sectors expected to drive it.
5. Notes – this section provides further information about the Dashboard methodology and data sources. It also includes an explanation of the rating symbology applied throughout the Dashboard.
6. Glossary – this section provides key definitions, including a description of the material categories used throughout the Dashboard.

Victorian major public infrastructure information provided to IA for the purposes of modelling is based on Budget Paper No. 4 of the Victorian State Budget.

Producer Price Indices are calculated on the index reference period 2011-12 = 100.0.

The Dashboard will be updated by DTF twice a year with any updated data that has become available.

The supply chain dashboard is informed by a wide range of information and sources. These are outlined in detail below:

Material definitions

Construction Aggregate (or ‘aggregate’): refers to coarse to medium grade particulate material used in construction, including gravel, crushed stone, slag or recycled concrete. For this Dashboard it primarily refers to the aggregate used for concrete, road base, roads and drainage.

Bitumen Binders (or ‘bitumen’): refers to the crude oil by-product used predominately for an aggregate binder for road construction but is also used in waterproofing in other forms of construction.

Cement: refers to the inorganic binder, often lime or calcium silicates. Primarily mixed with sand and aggregates to form concrete.

Rail Track: refers to the manufactured steel components of the railway line, rails and fasteners. For this Dashboard the sleepers are not considered in these figures.

Hard Rock: refers primarily to the larger bluestone aggregates used in rail ballast, foundations and drainage.

Sand: refers to the smallest of the aggregates and is primarily used in concrete production and foundation bases.

Reinforcing Bar Steel (or ‘rebar’): refers to the fabricated steel rods and mesh used to reinforce concrete.

Structural Steel: refers to non-rebar steel used in construction.

Timber: refers to the timber used in construction. Due to the winding down of hardwood production in the Victorian timber industry, this Dashboard focuses on plantation pine, usually MGP10, which forms the majority of Victorian Timber harvesting.

Other definitions

Plant: ‘Plant’ in construction covers mostly mobile capital equipment including cranes, scissor lifts, site offices, excavators, bulldozers, compactors and tunnel borers.

GSCPI: Global Supply Chain Pressure Index. A measure of worldwide supply chain demand pressure. Based on delivery time, backlogs and purchased stock. Measured as standard deviations from average.

DEECA: Department of Energy, Environment and Climate Action.

YoY: Year on Year, the change in figures from the same time period 12 months earlier.

QoQ: Quarter on Quarter, the change in figures from the time period 3 months earlier.

PPI: Producer Price Index, the measure of change in prices that domestic producers receive for goods and services.
The indexes are calculated on the index reference period 2011-12 = 100.0.

CQ: Current Quarter

PQ: Previous Quarter

Q1: Calendar Quarter one. January 1 to March 31, inclusive.

Q2: Calendar Quarter two. April 1 to June 30, inclusive.

Q3: Calendar Quarter three. July 1 to September 30, inclusive.

Q4: Calendar Quarter four. October 1 to December 31, inclusive.

FY: Financial Year. Where a single year is provided (e.g. FY2026), this refers to the 2026/27 financial year, from July 1, 2026, to June 30, 2027, inclusive.
