A major residential development in Adelaide's northern suburbs has entered a new phase after developer AVID Property Group decided to end its involvement in the Eyre community.

The Eyre development, located near Penfield between Edinburgh and Andrews Farm, was planned to eventually include about 1,900 homes across a 120-hectare site. Around 750 homes have already been completed, along with community infrastructure including sporting fields and a shopping centre.

Renewal SA, the South Australian Government agency responsible for the project, said AVID had decided to conclude its activities in the South Australian market. Responsibility for the future direction of the Eyre development will now return to the state government.

The change has raised questions about the remaining stages of the major housing project, particularly as Adelaide continues to experience demand for additional residential development. However, Renewal SA has said the project remains on track and that existing purchasers will not be affected by the transition.

South Australia's Acting Housing Minister Michael Brown said several hundred outstanding contracts would be honoured. Buyers who have already entered contracts for homes or land have been told they will continue to have their existing arrangements recognised.

AVID has also said it will continue to work on current commitments during the transition. According to information provided by the company, existing contracts remain in place, while work already underway will continue as responsibility gradually moves back to Renewal SA.

The developer's decision means the South Australian Government will now need to identify another commercial partner to continue delivering the remaining parts of the Eyre community.

The government has indicated that it intends to find a new development partner capable of taking the project forward. Renewal SA said the transition would not affect existing purchasers and that AVID would continue completing outstanding work associated with current stages.

That work includes landscaping, the delivery of a reserve and other infrastructure commitments. Some work is expected to continue through to the middle of 2027.

The Eyre project was originally announced in 2010 and was designed as a large-scale residential community in Adelaide's north. Its planned 1,900 homes make it a significant housing development for the region, while the completed sections have already established residential and commercial facilities for existing residents.

The decision comes at a time when housing supply remains an important issue across South Australia. Large residential projects such as Eyre can take many years to complete because they involve staged construction, roads, public spaces, community facilities and supporting infrastructure.

Master Builders Association South Australia chief executive Will Frogley described the developer's departure as disappointing and said stability in the construction market remained important.

The South Australian Government has said it expects to attract another major development partner. Renewal SA also indicated that other developers have previously shown interest in the Eyre project.

The transition therefore does not represent the cancellation of the planned 1,900-home community. Instead, the project is moving from one development arrangement to another, with Renewal SA taking responsibility for its future direction.

For existing residents and purchasers, the immediate focus is on ensuring current contracts and construction commitments continue without disruption. For the state government, the next major step will be finding a new commercial partner to oversee the remaining stages of the development.

The Eyre project is expected to remain an important part of Adelaide's northern growth, with hundreds of homes still planned beyond the approximately 750 already completed.
