A CFO's guide to how surety bond facilities work in Australia — structure, issuance, cost, annual review, and how a facility differs from a bank guarantee line.
A surety bond facility is a pre-approved aggregate bonding limit that allows a company to issue individual bonds within 24–48 hours, without submitting a separate application each time. Think of it as a revolving credit facility — but instead of borrowing cash, the company draws down guarantee capacity. An APRA-regulated surety underwriter carries the risk and issues each bond; a broker arranges and manages the facility. BCS Broking acts in that broker role — it does not carry the risk or issue the bonds.
This guide sits within BCS Broking's broader surety bonds for Australian construction and mining coverage. It explains what a facility is, how it is structured, how bonds are issued against it, what it costs, and how it differs from a bank guarantee line. For the step-by-step process of establishing one, see the companion guide on setting up a surety bond facility.
What a facility is — and why it matters
Without a facility, every bond a company needs is a fresh credit assessment: a new submission, a new approval, new security. For an operator tendering regularly, that is a recurring drag on time and bank capacity. A facility removes it. Once the line is in place, each bond is drawn against pre-approved capacity in a day or two, with no separate credit approval and no impact on bank facilities.
The structural difference from a bank guarantee is the key. A bank guarantee consumes the company's bank facility limits and often requires cash collateral. A surety facility sits entirely separate from banking lines and, for qualifying operators, requires no cash collateral — freeing both bank headroom and working capital. For the full comparison, see surety bonds vs bank guarantees.
How a facility is established
The process typically takes six to eight weeks from first engagement. The broker prepares a detailed financial submission to surety underwriters, including:
- Three years of audited financial statements
- Details of the management team and track record
- Current work-in-hand and project pipeline
- Existing guarantee and bonding obligations
- Growth strategy and target contract sizes
Surety underwriters assess performance capability — can this company deliver on the contracts it is bonding? — rather than requiring collateral. That assessment, not a cash deposit, is what supports the line. It is the fundamental difference from a bank guarantee facility. For the full setup walk-through, see setting up a surety bond facility.
Facility structure
A typical facility specifies four things:
| Element | What it means |
|---|---|
| Aggregate limit | Total value of bonds outstanding at any one time |
| Single bond limit | Maximum size of any individual bond |
| Approved bond types | Performance, maintenance, retention, advance payment, bid — and mining rehabilitation for resource operators |
| Premium rate | Charged on the face value of bonds actually issued |
Facilities start from around $1–2M at the entry level and scale into the hundreds of millions for larger operators. As financial performance improves and the track record strengthens, limits can increase at annual review.
Issuing individual bonds
Once the facility is established, issuing a bond against a new contract is straightforward:
- Notify the broker of the bond requirement.
- Provide the contract details and required bond wording.
- The bond is issued by the underwriter — typically within 24–48 hours.
No separate credit approval. No additional security. No impact on bank facilities. The bond wording matters: it must meet the principal's contract requirements (commonly an unconditional, on-demand undertaking under AS2124, AS4000 or AS4300). For the wording detail on the most common bond type, see performance bonds: AS2124, AS4000 & AS4300 compatibility.
Ongoing management
Facilities require an annual review with updated financial statements. Unlike bank facilities, there are no line charges or non-utilisation fees — the company pays premiums only on bonds actually issued.
The broker should also be actively managing bond releases as projects reach practical completion. Releasing a completed bond frees aggregate capacity for new work, so prompt release management directly affects how much tendering headroom the facility supports. This ongoing administration — issuance, release tracking, wording negotiation and renewal — is the broker's role; the underwriter provides the capacity and carries the risk.
What it costs
Annual premiums typically range from around 1–3% of bond face value, and higher for larger or higher-risk bonds, depending on financial strength, sector and facility size. There are no establishment fees and no non-utilisation fees — the cost is the premium on issued bonds.
Set against the effective cost of equivalent bank guarantees — which consume bank facility capacity and often tie up cash collateral earning little — the total cost of a surety facility is frequently lower once the opportunity cost of locked capital is counted. A representative scenario: a civil contractor with $80m revenue and a $15m aggregate bond book freed approximately $11m of cash collateral and equivalent bank headroom by moving renewing exposures to a surety facility. This is a representative composite, not a specific client outcome — actual results depend on the operator's credit profile, underwriter pricing and contract acceptance.
FAQ
What is a surety bond facility?
A pre-approved aggregate bonding limit under which a company issues individual bonds — performance, bid, retention, advance payment and others — as projects are won. It works like a revolving line, but draws down guarantee capacity rather than cash. An APRA-regulated underwriter issues the bonds; a broker arranges and manages the facility.
How quickly can a bond be issued against a facility?
Typically within 24–48 hours once the facility is in place. The company notifies the broker of the requirement and provides the contract details and bond wording; no separate credit approval is needed.
How long does it take to set up a facility?
Generally six to eight weeks from first engagement to a documented facility, depending on the underwriter's cycle and how quickly financials can be assembled. See setting up a surety bond facility for the step-by-step process.
Does a surety facility require cash collateral?
For qualifying operators with consistent profitability, generally no — the underwriter assesses performance capability rather than requiring a cash deposit. Weaker credit profiles may attract partial collateral.
Who issues the bonds — the broker or the underwriter?
The underwriter. An APRA-regulated surety underwriter issues each bond and carries the risk. The broker arranges the facility, prepares the submission and manages issuance and renewal. BCS Broking acts in the broker role. Confirm any underwriter on the APRA register.
What does a facility cost?
Premiums typically range from around 1–3% of bond face value (higher for larger or higher-risk bonds), charged only on bonds actually issued, with no line or non-utilisation fees. The rate depends on financial strength, sector and facility size.
How is the aggregate limit reviewed?
Annually, against updated financial statements and the forward pipeline. A growing, profitable operator typically sees the limit increase and pricing hold or improve at review.
Which bond types can a facility cover?
Performance, maintenance, retention, advance payment and bid bonds, plus mining rehabilitation bonds for resource operators — all drawn against one aggregate limit. See the performance bonds guide and bid and tender bonds guide.
