Assurance of Support (AoS) — the 10-Year Guarantee Inside Parent Visa Sponsorship

When families budget for a parent visa, most only look at the ~AUD 49,900 fee for the 143 — and overlook another financial commitment that sits at the end of the process: the Assurance of Support (AoS). This is not a tick-box declaration; it is a legal obligation lasting 10 years, backed by a real cash bond, with real debt-recovery consequences.

The short answer: the AoS is a commitment to Services Australia (the social security agency — not Home Affairs) that the assurer will repay recoverable Centrelink payments received by the sponsored parents while the AoS is in force. For contributory parent visas: a bond of AUD 10,000 for the main applicant plus AUD 4,000 for the second adult, held for 10 years from the date of arrival in Australia (for onshore grants the start point has its own rules — check the current provisions).

What the AoS is — and why it sits outside Home Affairs

The most common point of confusion: the AoS is not a Home Affairs process. The parent visa application progresses to the near-grant stage, at which point Home Affairs requests the AoS — but assessing the assurer, collecting the bond and managing the obligation is done by Services Australia (Centrelink) under social security law.

The legal substance: during the AoS period, if the sponsored parent receives certain recoverable Centrelink payments, that money becomes a debt owed by the assurer to the Australian Government — deducted from the bond first, with any shortfall pursued beyond it.

Bond amounts and duration — contributory parent visas

Operational points:

• The bond is lodged through the Commonwealth Bank under the mechanism Services Australia specifies; whether the bond earns interest and how it is returned at the end of the AoS period — check the current terms with Services Australia before lodging.
• If the 10 years pass without any debt arising, the bond is returned to the assurer.
• Other visa types that require an AoS (e.g. some non-contributory streams) have different durations and amounts — check the current rules for your family’s exact stream.

Note the “from the date of arrival” start point: for parents applying onshore, such as the 864/884, the start date is worked out under separate rules — confirm with Services Australia.

Who can give an AoS

The assurer does not have to be the sponsoring child on the visa — they are two distinct legal roles:

• An individual — usually the child, but any eligible person can do it.
• Multiple people jointly — sharing the obligation when one person’s income is insufficient.
• An organisation — in some cases.

The assurer must pass a Centrelink income test — the threshold depends on the number of assurers, the number of people being assured and family circumstances; the exact figures change periodically — check directly with Services Australia or have an adviser model it beforehand. Income is usually evidenced through recent tax records.

The real risks for the assurer — read before signing

This is the section we most want you to read slowly:

• The obligation is real and runs for 10 years. During the AoS period, recoverable payments received by the parents will be pursued from the assurer. The bond is only the first buffer — debt exceeding the bond is recovered beyond it.
• There is no mid-term exit once the visa is granted and the AoS is in force — even if family relationships change, even if the assurer hits financial hardship.
• Asking a friend or acquaintance to act as assurer is a very big ask — you are asking them to take on a 10-year financial obligation for someone who is not their parent. Conversely, if you are asked to be an assurer for someone else: understand exactly what you are signing, and do not hesitate to decline if unsure.
• The AoS is not a formality to “just sign off”, whatever some marketing suggests — Centrelink genuinely assesses, genuinely collects the bond, and genuinely recovers debts.

The AoS within the total cost picture of parent visas

Adding up the layers for a 143/864 application (2026–27 levels, both parents): visa fees of ~AUD 49,900 per person, an AoS bond of AUD 14,000 (refundable if no debt arises), plus health examinations, police checks, translations, and insurance for the period before Medicare. The bond may be “refundable”, but it is money locked away for 10 years — put it in the cash-flow plan rather than treating it as a phantom number.

For families who find the total burden too heavy, the 870 visa — which does not require an AoS — deserves a place on the scales.

Summary

The Assurance of Support is a 10-year legal commitment to Services Australia, not paperwork theatre: a AUD 10,000 + 4,000 bond for contributory parent visas, a genuine income test, and a repayment obligation that can exceed the bond. Deciding who gives the AoS deserves the same seriousness as deciding to lodge the visa — especially before asking anyone outside the family.
