Restoration works at Trinity Park are scheduled to begin late April, early May 2026. These works will be delivered in stages throughout the financial year, and the plan in the document library highlights the areas where activities will take place in 2026.

What works are happening in 2026?

This year’s works focus on restoring and strengthening the park landscape and include:

• Increasing the depth of the protective surface layer using mulch.
• Distributing native seed to encourage natural regeneration.
• Planting local native tube stock - view plant selections in the document library.
• Ongoing maintenance, including replacing plants that do not establish.
• Targeted weed control before and after planting.

These works will help stabilise slopes, support healthy plant growth and improve the park’s long‑term environmental resilience.

What will Trinity Park look like in the future?

The long‑term vision for Trinity Park is to create a space that offers something for everyone, including:

• Open grassed areas near the playground for informal play, picnics and community use.
• Increased shade and canopy trees to improve comfort and reduce heat.
• A three‑metre‑wide limestone walking and maintenance path.
• Expanded native bushland areas to support wildlife, provide shade and enhance slope stability.

Improvements will occur gradually, allowing the landscape to establish and improve year by year. View the park visualisation in the document library.

Why these works are needed

During the playground upgrade in 2021, investigations identified material close to the surface that confirmed the site was historically used as landfill. This means additional protective layers (known as ‘capping’) are required to ensure the park is safe and stable. The investigation also confirmed that the existing groundwater reticulation system needs to be decommissioned due to groundwater contamination.

Because of this, park improvements need to be carefully managed and include:

• Adding mulch to increase the depth of the protective layer
• Using bushland‑style planting, particularly on slopes, to prevent erosion and improve stability

While this places some limits on the types of landscaping and infrastructure that can be installed, the City is committed to making Trinity Park as safe, attractive and enjoyable as possible for the community.

What to expect during the works

While works are underway, you may notice:

• Temporary access changes in some areas of the park
• Mulch stockpiles and active restoration works
• Newly planted areas that will take time to establish

These impacts will be short‑term and carefully managed. Clear signage and ongoing updates will be provided throughout the project.
