Big Builds, Bigger Checks: NSW Navigates a Landscape of Mega-Projects and Regulation

NSW construction continues to see the expansion of major development activity, while pressure builds around utilities, approvals, and workforce settings.

NSW construction activity continues to be supported by a strong pipeline of government-backed infrastructure, with major projects such as Parramatta Light Rail Stage 2 [2, 6] and the Western Harbour Tunnel [11] progressing and sustaining demand across the sector. At the same time, recent reporting on Snowy 2.0 has brought renewed attention to delivery risk on large-scale projects, following further cost escalations and schedule extensions [9].

Alongside project delivery, regulatory oversight is increasing across multiple fronts. A new parliamentary inquiry into data centres has commenced [1], renewable energy projects are facing more complex federal environmental assessment processes [4], and a major labour hire network is under investigation by the ATO in relation to tax compliance [7].

In development, recent planning reforms are translating into renewed activity along long-stalled urban corridors, including Parramatta Road, where a $2.7 billion pipeline of projects is now emerging [12]. Government investment is also supporting construction activity in regional centres, adding to the overall volume of work across the state [10].

Infrastructure Pipeline Presents Opportunity Alongside Delivery Risk

Government-backed infrastructure projects continue to underpin construction activity across NSW, with several major programs moving into delivery. Main construction approval for Parramatta Light Rail Stage 2, supported by $3 billion in funding, is expected to generate more than 2,000 jobs and open a significant pipeline of works connecting Parramatta to Sydney Olympic Park [2, 6]. In Sydney’s inner west, works on the $7.4 billion Western Harbour Tunnel are progressing, including the underground assembly of two tunnel boring machines for the project’s next tunnelling phase [11].

Beyond metropolitan Sydney, longer-term infrastructure planning is also shaping the forward pipeline. The NSW Government’s strategic plan for the Sydney–Central West corridor outlines ongoing road and rail upgrades focused on safety, freight movement, and regional connectivity [3]. In the Hunter, local councils are seeking state and federal funding support for major projects, including a proposed $50 million freight terminal at Newcastle Airport [5].

At the same time, recent reporting on Snowy 2.0 has highlighted the delivery challenges associated with large-scale infrastructure. The project is now approximately 70 per cent complete, with costs increasing from an initial estimate of $2 billion to more than $12 billion and completion delayed to late 2028 [9]. Issues cited include difficult geological conditions, the acquisition of an additional $75 million tunnel boring machine, and a series of workplace safety incidents [9].

Together, these projects illustrate both the scale of opportunity and the delivery complexity present in the current infrastructure pipeline, particularly where technical, safety, and cost risks intersect on major works [9].

Regulatory Scrutiny Intensifies Across Planning, Environment and Supply Chains

Regulatory oversight across NSW construction is increasing, with new inquiries and enforcement activity emerging across planning, environmental assessment, and financial compliance.

A newly announced NSW parliamentary inquiry will examine the rapid expansion of data centres, focusing on energy and water consumption, land use impacts, and the use of fast-tracked planning approvals [1]. The inquiry places particular attention on cumulative infrastructure demand and whether existing planning frameworks adequately address environmental and community impacts associated with large, clustered facilities [1].

Environmental assessment requirements are also tightening for major energy infrastructure. The New England Renewable Energy Zone has been referred for assessment under the Environment Protection and Biodiversity Conservation Act, introducing a federal approval layer alongside state planning processes [4]. The referral reflects concerns about potential impacts on biodiversity and heritage areas and may affect project sequencing and approval timelines [4]. In the Riverina, the Dinawan Energy Hub is progressing through public hearings before the Independent Planning Commission, highlighting the continued role of detailed scrutiny and public consultation in major energy developments [8].

Compliance focus is extending beyond planning and environment into financial conduct within construction supply chains. A significant tax investigation into a labour hire network, alleged to owe $104 million in unpaid taxes, has involved asset freezing orders and multiple related entities [7]. The matter has drawn attention to the exposure faced by contractors engaging labour providers and subcontractors that do not meet tax and regulatory obligations [7].

Together, these developments indicate a broader regulatory focus across multiple aspects of project delivery, from approvals and environmental assessment through to labour and financial compliance [1, 4, 7].

Planning Reforms Open Urban Renewal and Regional Project Pipelines

Recent NSW Government planning reforms are enabling movement on projects that have remained stalled for extended periods, particularly in established urban corridors and selected regional centres.

Along Parramatta Road, state-led rezoning has increased permissible heights and densities, supporting a residential pipeline valued at approximately $2.76 billion and comprising 6,006 proposed dwellings [12]. Developers are now progressing site amalgamations for towers of up to 35 storeys, following years of limited development activity along the corridor [12]. The uplift is closely linked to supporting infrastructure, including the delivery of new Metro stations at Five Dock and Burwood North, which are intended to support higher-density development outcomes [12]. Parramatta Light Rail Stage 2 also forms part of this approach, with the alignment designed to support future housing precincts across Western Sydney [6].

Comparable patterns are emerging in regional NSW, where government-funded infrastructure programs are driving construction activity. In the Port Macquarie-Hastings region, the current pipeline includes a $265 million upgrade to the Port Macquarie Base Hospital, a $24 million road revitalisation project, and delivery of 94 social and affordable housing dwellings [10]. These projects form part of a broader investment program across health, transport and housing, supported by state and federal funding allocations [10].

Across both metropolitan and regional markets, planning reforms and infrastructure investment are directly influencing where development is proceeding and the scale at which projects are now being proposed [6, 10, 12].

Final Thoughts

NSW construction activity in 2026 reflects a mix of scale, intervention, and increasing complexity. Major transport and urban renewal projects are moving through delivery, supported by sustained government investment and planning reform [2, 12]. At the same time, recent experience on large projects such as Snowy 2.0 highlights the cost, scheduling, and safety risks that can accompany complex infrastructure delivery [9].

Regulatory scrutiny is also increasing across multiple fronts. Parliamentary inquiries, expanded environmental assessment requirements, and financial investigations are adding layers of oversight to planning, approvals, and supply chain management [1, 4, 7]. Together, these factors are shaping how projects progress, the conditions attached to delivery, and the compliance environment faced by developers, contractors, and consultants across the state.

The current pipeline remains active across transport, housing, energy, and regional infrastructure, but outcomes are increasingly influenced by regulatory settings, risk allocation, and delivery capacity rather than demand alone.
