The Australian hyperscale wave
Australian data centre capex is in an extended growth phase. Combined hyperscale operator capex 2026-2030 is forecast above AUD 30 billion across NextDC, Equinix, AirTrunk, Global Switch, Microsoft Azure, Amazon AWS, Google Cloud and emerging hyperscale players. HVAC ductwork represents approximately 1-2% of total project capex, meaning the addressable Australian data centre HVAC duct market is approximately AUD 300-600 million over the period.
For HVAC duct fabricators in Australia, the opportunity is to position as a preferred supplier on hyperscale framework agreements. This guide is a framework for Australian fabricators positioning for hyperscale work.
Standards and codes — Australian hyperscale data centre HVAC
- AS/NZS 4254.2 (high pressure) — binding for hyperscale data centre HVAC duct above 500 Pa. The dominant fabrication specification.
- AS/NZS 4254.1 (low pressure) — applies to lower-pressure system sections.
- NCC (National Construction Code) — mandates compliance with AS/NZS 4254 and AS 1668 for ventilation.
- AS 1668.1 — ventilation, fire and smoke control.
- AS 1668.2 — mechanical ventilation in buildings.
- AS 1530.4 — fire-rated duct construction for compartmentation walls and floors.
- NABERS Energy for Data Centres — 5-star+ ratings drive tight duct leakage requirements.
- SMACNA (sometimes) — US-led hyperscale operators (Microsoft, Amazon, Google) may overlay SMACNA on top of AS/NZS 4254. Fabricate to the tighter of the two.

Capex for an Australian hyperscale-ready fab shop
For an Australian fabricator targeting hyperscale framework agreements:
- Equipment ex-works Taokron: quoted to specification — Taokron withholds published pricing, so request an itemised quotation
- CIF Sydney/Melbourne port + duty + customs broker + inland trucking: AUD 150,000–250,000
- Building lease and fit-out (typical 1,500–2,500 m² shed in Western Sydney or Tullamarine): AUD 100,000–250,000 first year
- Total turnkey capex: machinery (quoted to specification) plus the landed logistics and building fit-out above — request an itemised worksheet
This shop can sustain rectangular plus spiral round duct production, sufficient for one hyperscale project at any given time on multi-shift. Dual-line shops (2 SBAL-V cells) capable of multiple concurrent hyperscale projects carry a correspondingly higher turnkey capex — request an itemised quotation.
Australian labour cost reality
Australian sheet metal fabrication labour is among the highest in the world. Approximate fully-loaded annual cost (2026, AUD):
- Senior fabrication supervisor: AUD 110,000-150,000/year
- HVAC fitter / sheet metal worker (qualified): AUD 80,000-110,000/year
- SBAL-V auto duct line operator: AUD 75,000-105,000/year
- Sheet metal welder (AS qualified): AUD 90,000-125,000/year
- QA/QC engineer: AUD 100,000-140,000/year
- Project / contract manager: AUD 130,000-180,000/year
The high labour cost is the strongest case for automation — an SBAL-V running at 18 m/min with one operator can replace several manual fabricators. Payback depends on your volume and labour cost, so model it on your own numbers. See our 5-year TCO model.
NABERS Energy implications for duct construction
NABERS Energy for Data Centres rates the operating energy efficiency of the facility. Higher star ratings (5+) require very low fan energy, which translates to:
- Tight duct leakage class — AS/NZS Class C at minimum, often Class D for 5+ star projects
- Efficient air distribution — duct sized for low velocity, low pressure drop
- Tight zone control — variable air volume (VAV) terminals integrated with the BMS
- Continuous insulation on supply duct to minimise heat gain in plant rooms and risers
Tight leakage class makes FAT-tested duct fabrication non-negotiable. Ask your supplier how leakage-class testing of sample duct is handled in the factory acceptance test.

FAQ
Which standard applies to Australian data centre HVAC duct?
AS/NZS 4254.2 (high pressure above 500 Pa). AS/NZS 4254.1 for low pressure. NCC mandates both. SMACNA may overlay on US-led projects.
Where are Australian data centres concentrated?
Sydney (Macquarie Park, Mascot, Erskine Park, Western Sydney) is largest. Melbourne (Tullamarine, Port Melbourne, Derrimut) is second. Brisbane, Perth, Canberra smaller. Geelong and Wollongong emerging.
What hyperscale operators are active in Australia in 2026?
NextDC (S5 Sydney, M3 Melbourne, B2 Brisbane), Equinix (multiple SY and ME sites), AirTrunk (SYD1, SYD2, MEL1, MEL2), Global Switch, Microsoft Azure (multiple), Amazon AWS (multiple), Google Cloud (multiple), and growing global hyperscale interest. Combined Australian hyperscale capex 2026-2030 is forecast above AUD 30 billion, with HVAC ductwork representing approximately 1-2% of total project capex.
How does NABERS Energy affect duct construction?
NABERS Energy for Data Centres rates the operating efficiency of the facility's energy use; it does not directly mandate duct construction details. However, achieving 5+ NABERS star rating typically requires very low duct leakage (AS/NZS Class C or tighter at acceptance test), efficient air distribution to minimise fan energy, and tight HVAC zone control. Tighter leakage class increases the importance of FAT-tested duct fabrication and SMACNA Class A or AS/NZS Class C sealing.
What is the typical Australian data centre HVAC duct contract size?
For a typical Australian hyperscale 30-50 MW data centre, HVAC ductwork supply is approximately AUD 5-15 million across the project, distributed over 12-18 months. The fabricator needs to deliver 6,000-12,000 m² of finished duct per project — sustainable on a single SBAL-V auto duct line running multi-shift. Mid-tier 5-15 MW colocation projects are AUD 1-3 million. Frameworks with hyperscale operators are typically multi-project, 3-5 year arrangements.
