Residential Bonds Online SA

What Residential Bonds Online Does

Residential Bonds Online (RBO) is the online service Consumer and Business Services (CBS) operates for lodging, managing, and disposing of residential tenancy bonds in South Australia. Every bond collected from a tenant must be lodged with CBS for the Commissioner for Consumer Affairs; RBO is the online option, and holding the bond in your own account is not a substitute for lodgement.

The system handles the full lifecycle: initial lodgement, address changes, partial refunds, full refunds at the end of a tenancy, and disputed dispositions that need to go to the South Australian Civil and Administrative Tribunal (SACAT).

Lodgement Deadlines and Penalties

Under the Residential Tenancies Act 1995, a landlord or proprietor must lodge the bond with CBS within two weeks of receiving any part of it. A registered land agent has four weeks. The maximum bond is four weeks' rent when weekly rent is $800 or less, and six weeks when weekly rent is more than $800. A tenant must also receive a bond receipt within 48 hours.

Failure to lodge a bond with the Commissioner carries a maximum penalty of $35,000. That figure increased under the 2023 amendments and is among the highest single-offence fines in the Act. CBS doesn't need the tenant to complain — an audit or a SACAT proceeding can surface an unlodged bond.

How to Lodge a Bond Step by Step

1. Collect the bond from the tenant (cash, direct transfer, or electronic payment) and give a receipt within 48 hours.
2. Lodge it with CBS within the applicable two- or four-week deadline. Residential Bonds Online is the online lodgement option; CBS also accepts manual lodgement.
3. Enter the tenancy details: property address, tenancy start date, tenant names, and the bond amount.
4. Submit the payment to the Commissioner's trust account using the reference number RBO generates.
5. Both landlord and tenant receive a confirmation notice with the bond reference number.

Keep the bond reference number in your tenancy file. You'll need it for every future action — condition-related claims, partial refunds, or full disposition.

Bond Disposition at the End of a Tenancy

When the tenancy ends, both parties need to agree on how the bond is split. If there's no dispute, the landlord or tenant submits a claim through RBO and the other party confirms. CBS can process an undisputed refund within five working days; an electronic funds transfer is estimated to take 24–48 hours.

If the landlord claims part of the bond for cleaning, damage, or unpaid rent, they need to substantiate it. This is where the property inspection sheet from the start of the tenancy becomes critical. The Residential Tenancies Regulations 2025 require a signed condition report at commencement. Without one, proving the tenant caused damage rather than inheriting it is nearly impossible at SACAT.

When Disposition Is Disputed

If the tenant and landlord can't agree, either party can apply to SACAT for a determination. The standard filing fee is $93 as of July 2026. SACAT will look at:

• The signed inspection sheet from the start of the tenancy
• Photographs or video taken at commencement and vacating
• Repair invoices and applicable trade Certificates of Compliance for any work done
• The tenant's compliance with their obligation under Section 69 to keep the property reasonably clean

Landlords who maintain a dated evidence trail — inspection photos, repair logs, and trade certificate records — consistently do better in bond disputes than those who rely on memory.

Common Mistakes Self-Managing Landlords Make

Lodging late. Some self-managing landlords collect the bond and forget to lodge it for weeks. Each day beyond the applicable lodgement deadline is a day of non-compliance.

Not completing the inspection sheet. The condition report is your baseline. Without it, the bond disposition is a he-said-she-said exercise.

Claiming for fair wear and tear. Section 68 requires the landlord to maintain the property in a reasonable state of repair, and normal wear is the landlord's cost. Faded paint, worn carpet in traffic areas, and minor scuffs are not tenant damage. Overclaiming erodes credibility at SACAT and can result in the entire claim being dismissed.

Mixing bond and rent accounts. The bond is trust money. Never use it to cover unpaid rent unless the tenancy has ended and both parties have agreed or SACAT has ordered it.

Linking Bond Lodgement to Your Compliance File

Bond lodgement is one piece of a broader pre-tenancy compliance sequence under SA law. Before the tenant moves in, you also need to ensure the property meets the minimum housing standards under the Housing Improvement Regulations 2017, issue the mandatory Form A1 rental application, provide the CBS Tenant Information Guide, and complete the property inspection sheet.

The SA Rental Minimum Standards guide consolidates these steps into a single pre-let workflow, including the audit logs and record-keeping templates that protect your position in a bond dispute.
