Supplementary Election

A supplementary election in local government is held to fill a vacancy that occurs between regular election cycles. This can happen if a council member resigns, passes away, or is otherwise unable to continue in their role. These elections ensure that the council remains fully staffed and can continue to function effectively.

In South Australia, the Electoral Commissioner oversees these elections, ensuring they are conducted fairly and transparently.

The process involves:

• notifying the public of the vacancy
• opening the voters roll for the supplementary election
• accepting nominations
• conducting the vote (via postal ballot)

The voters roll for the 2025 City of Adelaide Central Ward Supplementary Election is open until 30 May 2025.

If you are a resident and correctly enrolled for state elections in South Australia, you are automatically included on the council voters roll and will receive ballot papers through the post when a supplementary election is held.

If you need to check or update your enrolment, you can choose one of the following options:

• Check my enrolment
• Enrol to vote or update your details

It's not just residents who can enrol for Local Government Elections. The broad categories for enrolment are:

• Individual (sole property owner/occupier)
• Landlord
• Body corporate (sole owner/occupier)
• Group (joint owners/occupiers of a property)

Eligible voters are those who are enrolled on the voters roll for that specific ward at the close of the roll for the supplementary election.

This includes:

1. Residents (Standard Enrolment)

• People enrolled on the State (Electoral Commission) roll for that address.
• You must live in the ward and be properly enrolled with your current address.

2. Residents (not entitled to be on the State Electoral Roll)

• Residents who are not entitled to be on the State electoral roll (for example non-Australian citizens), may apply directly to Council to be enrolled if they meet the residency criteria by completing this form: Form 1 – Application for Enrolment on the Voters Roll.

3. Residential or Commercial Property Owners, or Commercial Occupiers/Tenants (Council Roll)

• You don’t have to live in the ward, but if you own, occupy, or lease a property in the ward (as an individual or business), you can register to ensure you are included on the council supplementary voters roll.
• This means business owners, landlords, and even companies can vote - but you must be registered before the roll closes.

Use the Voters Roll Checker tool to determine whether the City of Adelaide has your details as an owner of a commercial property, or occupier/tenant of a commercial property on our Council Voters Roll. If not, fill in the City of Adelaide’s Voters Roll - Registration Form to register your details by 30 May 2025.
