We're proud to share that development approval has been granted by The Hills Shire Council for a 9-lot rural cluster subdivision at 2914 Old Northern Road, Glenorie.
This project demonstrates the value of an integrated, multidisciplinary approach to complex rural development projects and highlights the strength of the GDS team across planning, engineering, environmental and project management disciplines.
Key project highlights included:

🌿 Ecology
Completion of 12 months of ecological survey fieldwork and reporting to support the subdivision design and assessment process.
🔥 Bushfire Planning
Successful justification that no perimeter road was required, with excellent support from Blackash Consultants.
📐 Engineering
A detailed design for the community road and drainage infrastructure.
📋 Town Planning
Achievement of an additional lot yield through a well-considered planning strategy.
Preparation of a robust Clause 4.6 Variation Request that was positively received by both Council officers and the Local Planning Panel.
🤝 Project Management
Coordination of multiple technical disciplines, stakeholders and evolving project requirements to achieve a successful outcome.

Projects like these reinforce the value of collaboration, technical excellence and persistence when navigating complex development approvals.

A fantastic result for our client and a great example of what can be achieved when planners, engineers, ecologists and specialist consultants work together towards a common outcome.

Work has started at 173 Samantha Riley Drive, North Kellyville. Demolition and tree removal are underway with ABAX Civil Contracting clearing the way for 7 residential lots and a new road.
Every project starts with groundwork, and this one is off to a solid start. More updates to come as the site takes shape.

The draft Illawarra Shoalhaven Plan is now on public exhibition. GDS Planning team has been reviewing the draft and its implications for the region's five LGAs.

Setting the strategic land use framework for the next 20 years, the NSW Government's plan forecasts 161,000 more people, 117,000 more homes and 101,850 more jobs across the Illawarra Shoalhaven region by 2046, covering Wollongong, Shellharbour, Kiama, Shoalhaven and Wingecarribee.

For developers and landowners, the Plan signals a defined urban growth area, a stronger push on housing diversity and choice, and growth concentrated around Transport Oriented Development at Corrimal, Dapto and North Wollongong, alongside Low and Mid-Rise housing opportunities across the region's centres.

It also flags major land use shifts to watch — the transformation of BlueScope's surplus industrial lands at Port Kembla, Australia's first Urban Renewable Energy Zone, and a strengthened strategic relationship between the region and south-west Sydney.

For clients holding land or considering subdivisions, rezonings and development projects across the Illawarra Shoalhaven, this draft is a real opportunity to shape the final plan through the exhibition process, as well as an early signal of where future rezoning and yield opportunities may emerge.

If you have landholdings or development interests in the region, now is the time to review how the draft Plan may affect your site and to consider a submission during exhibition.

📞 Contact the GDS team to discuss your site's position under the draft Illawarra Shoalhaven Plan.

The Sydney Plan is now in force. GDS Planning team attended the NSW PIA Briefing Session for The Sydney Plan and NSW Land Use Plan.

With Sydney's population forecast to exceed 6.6 million people by 2046, the NSW Government has introduced a new 20-year strategic land use framework that will shape housing, jobs, infrastructure and investment across Greater Sydney.

For developers and landowners, the Plan signals a stronger focus on housing delivery, feasible housing capacity, housing diversity and future rezoning opportunities. It also requires councils to plan for 30 years of feasible housing capacity and investigate opportunities for additional housing growth.

For clients involved in land subdivisions, rezonings and development projects, these reforms may create new opportunities to unlock development potential and increase yield in the right locations.

If you're considering a subdivision, planning proposal or strategic landholding opportunity, now is the time to understand how the Sydney Plan may impact your site's future potential.

📞 Contact the GDS team to discuss the subdivision and development opportunities arising from these planning reforms.

250-260 Bringelly Road, Austral — Project Update 📈
Site possession for this 85 lot residential subdivision with 2 x super lots in March 2026 - 1.5 years of civil works close to reaching practical completion at the end of July 2026.
The project has delivered new public roads, all utilities and stormwater infrastructure complete with rain gardens and a masterpiece drainage swale, bringing new life to the Austral growth precinct, setting the stage for the residential lots to come online.
Getting here wasn't without its hurdles — a lengthy DA, SWC and Sydney water approval process and a run of challenging weather conditions tested the program at every turn.
Credit to the collaborative efforts of the Planning, Engineering, PM team and Civil contractor – to bring this one to a strong finish.
With civil works now complete, focus turns to the next stage of delivery – Subdivision Certificate and Registration.
Keep them coming, ready for the next one!
