The 1.4GW Bungaban Wind Farm will be located 40km north-east of Wandoan and will generate enough energy to power 700,000 homes.

Powerlink has been engaged by renewable energy company Windlab to investigate transmission line connection options for the wind farm.

Connection works will include:

  • building a new substation at the wind farm site
  • constructing a double circuit 275kV transmission line between the wind farm and Powerlink’s existing Wandoan South Substation.

Final corridor

Powerlink released a high-level study area for the project in July 2024. Feedback and insights gathered at that time, combined with desktop analysis, helped identify two 1km-wide corridor options which were released for public comment in November 2024.

Feedback collected during November and December 2024 highlighted an area within corridor option 1 (south) for further investigation.

In April 2025, we released a 1km-wide recommended corridor and engaged with landholders, Traditional Owners, community and other stakeholders to help inform the final corridor.

Based on the feedback received, five realignments were made to the recommended corridor, resulting in the final corridor now being released:

  • Knudsens Road refinement

Shifting the corridor further north of Knudsens Road allows more flexibility in designing the transmission line.

  • Old Chinchilla Road/Roche Creek Road deviation

Realignment of the corridor to the east to enable co-existence through a proposed renewable energy project and current land uses. This section of the final corridor has been reduced to 300m, to accommodate broader constraints in the area.

  • Hansens Road and Peak Road refinement

Shifting the corridor further east to more closely align with property boundaries and reduce potential impacts on activities such as aerial mustering and potential conflicts with other proposed infrastructure.

  • Giligulgul Road/Hansens Road refinement

A minor straightening of the corridor was applied to more precisely follow property boundaries and to accommodate other proposed infrastructure.

  • Columboola Transmission Line co-location refinement

The Columboola easement widening now allows 100m of space both north and south of the Columboola easement, replacing the previous 200m exclusively to the north. This change enhances design flexibility and accommodates existing and planned infrastructure developments.

The final corridor has achieved the following:

    • traverses fewer land parcels and is located further away from residential properties
    • traverses a smaller area of strategic cropping land
    • intersects smaller areas of endangered and ‘of concern’ vegetation

Importantly, landholder preferences, ongoing property operations, and future development plans were carefully considered alongside the interests of gas and renewable energy proponents to support the shared use of land for agriculture, infrastructure, and other development within the area.


Social Impact Assessment

Powerlink has engaged an independent specialist to undertake a social impact assessment (SIA) for the Bungaban Wind Farm Connection Project. This is an opportunity for you to have a say about how the project may affect the community and what benefits could exist.

Who is undertaking the SIA?

All things Social Impact (ATSI) alongside Ochre Social Performance is undertaking the SIA. Their job is to listen, gather, and analyse feedback fairly, then report their findings.The SIA findings will help us with project planning, impact management, and community benefit initiatives.

How can I get involved?

There are two ways you can contribute:

  • Community Survey- complete the survey online via or via paper copies available at the Wandoan Post Office.
  • Chat & Connect sessions- come and chat with the team in Pocket Park/Cafe on Wednesday and Thursday 20 and 21 May between 8am - 1pm.

Questions about the SIA

For more information on the Social Impact Assessment:

Survey closes 12 June 2026.


What’s next?

Powerlink will continue engaging with impacted landholders to negotiate up to a 100m-wide easement alignment within the final corridor.

On-site studies will continue, including ecology, hydrology, land practices, terrain, flora and fauna, cultural heritage and visual amenity. These studies will be used to inform the detailed design of the transmission line and support necessary planning and environmental approvals.

Commonwealth Government approval

We submitted our project referral under the Environmental Protection and Biodiversity Conservation Act 1999 (EPBC) in December 2025. It was open for public comment until 19 January 2026. On 3 February 2026, the Federal Department of Climate Change, Energy, the Environment and Water (DCCEEW) determined that our project is a controlled action, meaning it requires further assessment and approval under the EPBC before it can proceed. You can view the decision notice on the EPBC Portal.

DCCEEW specified the project will be assessed by preliminary documentation (PD), which examines the project’s potential impacts on protected matters (plants, animals, habitats and places) and proposed management measures. Our team is preparing this report and will notify you when it is open for public feedback.

State Government Planning approval

The project will also need to go through State planning approvals processes, and we’ll keep you updated as both approval pathways progress.

Our project team will continue to communicate and engage with landholders and the broader community throughout all stages of the project.


Frequently asked questions

The final corridor is predominantly 1km-wide and will continue to be narrowed further up to a 100m-wide easement alignment following further investigation and engagement with landholders.


Between November and December 2024, we sought input from landholders, Traditional Owner groups, community members and other stakeholders on the corridor options identified through the study area engagement.

Over that period, key engagement activity included:

  • four community information drop-in sessions at Wandoan Cultural Centre (15 attendees)
  • landholder letters (26)
  • feedback forms (10 responses)
  • dedicated project website (675 visits)
  • Social Pinpoint interactive mapping tool (2 individual comments posted)
  • community information webinar (15 registrations and 39 views of recording)
  • targeted stakeholder meetings and council briefings
  • emailed project newsletter to subscribers (64 recipients)
  • emails and phone calls with the local Traditional Owner group (Iman People)
  • distribution of 320 reminder flyers promoting feedback channels and information sessions
  • social media advertisements promoting the project website and information sessions.

Prior to this, between July and September 2024 we sought input on the proposed study area through the following activities:

  • six community information drop-in sessions at Chinchilla, Miles, Wandoan and Taroom (49 attendees)
  • landholder letters (56) and telephone calls (26)
  • feedback forms (27 responses)
  • dedicated project website (1,102 visits)
  • Social Pinpoint interactive mapping tool (30 individual comments posted)
  • stakeholder meetings and council briefings
  • meetings with the local Traditional Owner group (Iman People)
  • distribution of 500 project newsletters and cards promoting feedback channels and information sessions
  • podcast episode detailing the project, timings and feedback avenues (38 downloads)
  • print, radio and social media advertisements promoting the project website and information sessions.


Key themes raised during corridor options engagement were:

  • property impacts throughout construction
  • future development opportunities including co-existence with other renewable energy projects
  • impact on farming operations including aerial activities
  • loss of productive and developed agricultural land
  • visual impacts
  • proximity to homes
  • biosecurity
  • community benefits
  • compensation.


Yes – Powerlink’s Indigenous Partnerships Team has engaged with the Iman Board and Elders on multiple occasions to seek their insights and feedback on the corridor options. Their feedback has been greatly appreciated to help our Project Team build awareness of culturally significant areas.


The recommended corridor offers the least overall impact on balance across social, environmental and economic objectives. The methodology used to guide the corridor selection process has involved looking at all the data compiled through mapping and other desktop analysis, as well as feedback received from landholders, Traditional Owner groups, the community and other stakeholders.

Corridor option 1 (south) was identified as the preferred option over corridor option 2 (north) due to the following reasons, as it:

  • impacts fewer land parcels and properties, and there are fewer houses within 1km of the corridor, slightly reducing its social and visual impact.
  • is a shorter and more direct route between the wind farm and the existing substation
  • intersects less strategic cropping land
  • intersects less remnant and regrowth vegetation.

Feedback collected on the corridor options highlighted an area within this corridor for further investigation. Our consultation on this took place in March 2025, which aimed to understand future land use and coexistence opportunities. Feedback received during this period, and ongoing technical analysis, has resulted in further realignments to:

  • intersect less remnant vegetation
  • follow property boundaries where practicable
  • maximise potential co-existence with future farming and development opportunities (such as renewable energy developments)
  • consider the preferences of landholders, where possible.

It’s important to keep in mind the corridor is not yet finalised, and further refinements may be made before the final corridor is released. We will then work closely with directly impacted landholders to conduct on-site land studies to determine an easement alignment for the transmission line up to 100m wide.


With every transmission connection project, we need to take a strategic, whole-of-system view and ensure our infrastructure will safely, reliably and economically meet current and forecast demand. A key priority is minimising impacts on landholders, Traditional Owner groups and the surrounding community.

The easement for this transmission line will be up to 100m wide to accommodate the proposed line and potentially an additional line if required at a later stage to meet future demand whilst minimising ongoing disturbance.


At this stage, your property is not being considered as part of our investigations.

However, as the corridor is being finalised, there is potential that new information from engagement feedback or on-ground assessments may result in minor adjustments to corridor positioning. If this occurs, we will promptly contact impacted landholders to discuss these adjustments.


We are currently at Step 4, 5 and 6 of Powerlink’s Transmission Easement Engagement Process (TEEP) - Final corridor, On-site land studies and Easement alignment and negotiations.

We continue to engage with landholders to refine the easement alignment for the transmission line within the final corridor. This includes onground studies and assessments which feed into the Commonwealth and State Government environment and planning approvals process.

We are moving into step 7 of the TEEP which involves Commonwealth and State Government approvals.
