The Hunter Transmission Project, the 500 kV line from Bayswater to Olney, was approved on 27 July 2026, according to the NSW Major Projects register. Part of its construction workforce will sleep in a camp at the Hebden Road construction support site, which EnergyCo’s exhibition fact sheet places at Muswellbrook, up to 300 workers. The council’s 17 April 2026 letter to the Department of Planning, Housing and Infrastructure says it has resolved to OBJECT to the camp, because it will provide poor living arrangements for workers and minimal positive legacy for Muswellbrook Shire (p. 1).

The approval kept the camp. Read against the council’s letter, its conditions give the council some of what it asked for, and not the legacy its policy puts first: accommodation that stays and becomes housing or visitor accommodation. EnergyCo’s answer, as the council’s letter reproduces it, is that the site is leased from AGL, so there would not be an opportunity to repurpose the site once construction is complete (p. 5).

What the council asked for, and what the approval says

Muswellbrook adopted a Temporary Workforce Accommodation Policy on 23 September 2025, the day before the project’s exhibition closed. It says the council prefers TWA to be within or near existing urban areas and villages, gives preference to proposals with a pathway for permanent conversion, supports dry mess facilities to improve safety and encourage use of local hospitality venues and wants food, laundry and labour bought locally (sections 4.1 and 4.3). The April letter applies that policy to the Hebden Road camp, item by item. The Instrument of Approval answers in conditions B66 to B73.

Six things Muswellbrook asked for, against the approved conditions

Council requests from its 17 April 2026 letter; conditions from the Instrument of Approval, 27 July 2026. The tags are our reading.

  • Where it goes
    Not changed
    Council askedNo out-of-town camps, its position since May 2024; it sent EnergyCo a site suitability assessment of alternatives (pp. 1 to 2, 4). Approval saysCamps described in the EIS and in Appendix 1 of this approval; the EIS camps include Hebden Road (B66, B67).
  • What it leaves
    Different
    Council askedIf it stays at Hebden Road, water and wastewater built to permanent standards for a legacy use (comment 4, p. 5). Approval saysAll camps decommissioned and rehabilitated within 12 months of commencing operations, infrastructure removed to 500 mm, unless the Planning Secretary agrees otherwise (B73, Table 1).
  • Who sleeps there
    As asked
    Council askedProject construction workers only: Any proposal to accommodate workers from other projects should be prohibited (comment 6, p. 6). Approval saysCamps must only be used to accommodate workers associated with construction or road upgrades for the development (B67).
  • Local spending
    Partly
    Council askedLocal procurement targets and a plan showing how they will be met (comment 7, p. 6). Approval saysMeasures to support local suppliers in servicing the camp where possible; no targets (B68(g)).
  • Design
    Later
    Council askedAn indicative design before approval (comment 8, p. 6). Approval saysA management plan with site layout, capacity and staging, prepared before construction in consultation with relevant Council/s (B68).
  • Housing pressure
    Partly
    Council askedA Workforce Accommodation Strategy, with six-month notice of demand and triggers (comment 11, pp. 7 to 8). Approval saysA social impact management plan covering housing availability and affordability, with quarterly public monitoring reports (B71).
Sources: Muswellbrook Shire Council, comments on the Submissions Report and Amendment Report, 17 April 2026; Hunter Transmission Project Instrument of Approval, SSI-70610456, conditions B66 to B73 (pp. 34 to 37). Quoted words are the documents’ own.

The Department’s assessment report summarises Muswellbrook’s position (Table 6, p. 27) as having Requested clarification on the proposed TWA including its location, scale, and potential impacts on tourism and local services. We found no reference in the report to the objection in the council’s April letter. The preceding page (p. 26) says the Department met Singleton and Cessnock councils during the assessment.

Why the camp stays where it is

The council’s letter quotes EnergyCo’s reply of 24 March 2026 (p. 4). EnergyCo did a desktop analysis of the 14 sites the council identified; two, both council-owned, rated medium suitability. Moving the camp, it said, would mean A modification to planning consent (at a minimum a 4-month delay to the project), Additional cost of approximately $5 million and Potential social licence issues with additional community consultation required. The council disagreed that a modification would be needed: it says a camp approved through the state’s construction workers accommodation pathway can serve several projects, and it is not clear why use of an alternative site would require a modification to the HTP planning consent.

On legacy, EnergyCo told the council it is exploring alternative opportunities to deliver legacy outcomes, which may include supporting enabling infrastructure (e.g. roads, electricity, water and sewer) at a Council-identified site, and that it is committed to working with Council (pp. 4 to 5). The council’s reply: it is yet to see these opportunities clearly defined or progressed. Nothing in the approved conditions refers to such an arrangement.

Hebden Road is one of three camps. The figures have moved since exhibition, and EnergyCo’s project page, as at 7 October 2026, still gives the exhibited version: three sites, space for around 780 workers.

Exhibited figures from EnergyCo’s construction support sites fact sheet (Hebden Road, Gouldsville Road and Freemans Drive, Cooranbong). Assessed: the assessment report (p. 2) gives Three TWAs for a combined total of up to 900 workers at Hebden Road, Freemans Drive and Wollombi Road and the new Wollombi Road camp at up to 300 (p. 100); Hebden Road’s 300 is EnergyCo’s figure in the council’s letter (p. 5), and Freemans Drive’s 300 is the fact sheet’s, which together sum to the 900. Singleton Council’s advice quotes EnergyCo: the camp has been removed from the Gouldsville Road construction support site.

EnergyCo also told the council the camp’s capacity will be further refined by the appointed construction contractors and will be bound by the lease agreement between AGL and EnergyCo (p. 5), and that its design will be subject to the preference of the design and construct contractor(s) yet to be appointed (p. 6).

How it got here, and what lands at the same time

The council says it raised the location early and was not heard. EnergyCo’s responses in the same letter describe meetings and ongoing discussions. The dates, as the documents give them:

The Hebden Road camp, from the council’s first objection to construction

  1. May 2024Council’s submission on the project’s assessment requirements says it does not support out-of-town camps.
  2. 27 Aug to 24 Sep 2025Environmental impact statement on exhibition, with the Hebden Road camp for up to 300.

Council events in shiraz, project events in blue, expected events greyed. Sources: Muswellbrook Shire Council letter, 17 April 2026, pp. 1, 2, 4 and 8; the council’s policy MSC082E; assessment report p. 2; NSW Major Projects register; the council’s 3 September 2026 release. The solar farm, battery and bypass dates are the council’s description of other proponents’ plans, not those proponents’ own statements.

The other projects at the bottom of that list are what the letter keeps returning to. It says that multiple projects (mining, infrastructure and renewable energy based) are proposing arrangements that place pressure on both short- and long-term accommodation within the Muswellbrook Shire, and that without a coordinated approach unacceptable pressure on local rental vacancy rates and affordability may arise (pp. 7 to 8).

The council’s own move

Just over five weeks after the approval, on 3 September, the council invited expressions of interest from developers, investors and operators in providing worker accommodation in the shire. The EOI document says the council has identified several strategically located properties and describes three models: a tourist park taking up to 50 beds, worker camps of 150 to 300-plus beds on a build, own, operate, deconstruct model, and 51 to 150 beds of longer-term accommodation for essential workers with Long-term legacy accommodation outcomes. It is a non-binding market sounding exercise and not a procurement, tender or request for proposal. It closed on 18 September.

Muswellbrook Shire Council supports TWA that leaves the Shire better off, not accommodation that isolates workers on the edge of town and packs up without a trace
Mayor Jeff Drayton, Muswellbrook Shire Council media release, 3 September 2026.

As at 7 October 2026, the council’s worker accommodation news tag listed only the 3 September release, with no published outcome of the expression of interest.

How we read the documents

The council’s letter and Singleton Council’s advice are under “Agency Advice” on the project’s Major Projects register page, and the assessment report and Instrument of Approval under “Determination”. Page numbers for the assessment report are its printed numbers, which run 11 behind the PDF page index. EnergyCo’s words in this story are as the council’s letter reproduces them from EnergyCo’s 24 March 2026 email; we have not seen the email itself. The letter also mentions a meeting with EnergyCo on 12 November 2026, a date after the letter itself; we have not used it. The assessment report’s amended-project table (p. 100) says the Gouldsville Road camp would remain, while its project description (p. 2) and Singleton Council’s advice put the three camps at Hebden Road, Freemans Drive and Wollombi Road; we follow p. 2. We searched the assessment report for every mention of Muswellbrook and of objections to find what it records of the council’s position. The council’s EOI document is an image PDF with no text layer; we read it page by page. Arithmetic: 300 + 180 + 300 = 780; 3 × 300 = 900. We did not contact the council, EnergyCo or the Department.

Our read

This section is opinion, based on the facts and documents above.

The approval treats the camp as construction equipment, and the council wants it treated as housing. Both are reasonable. A state approval for one line has to make that line clean up after itself, and EnergyCo does not own the land. But the cost of the gap falls on Muswellbrook, which on the council’s own list has a solar farm, a battery and a highway bypass starting or peaking in the same months. This approval asks the project’s social impact plan to consider cumulative impacts with other State significant projects (B71); it does not, and one project’s approval is a poor tool to, set up a shared accommodation plan for all of them.

The useful next step is a written one. EnergyCo has said it will work with the council on legacy outcomes at a council site. The council says it has not seen them defined. The camp’s management plan is due before construction and has to be prepared with the council; that is the natural place to put whatever is agreed on paper, where the shire can read it.

What to watch next

The accommodation camp management plan and the social impact management plan must be prepared before construction starts (B68, B71). B71 requires quarterly monitoring reports to be publicly available on the project website, which will be the first public measure of the project’s effect on housing. The other is whatever the council does with the responses to its expression of interest.
