Quick answer
An acceleration clause is a term in a loan agreement that lets the lender demand the whole outstanding balance at once if the borrower defaults, instead of waiting for the remaining scheduled repayments. In Australian business loans it is usually triggered by missed payments, insolvency events or breached conditions. Banks bound by the Banking Code of Practice must generally give small business customers notice and time to fix the default first.
Key points
- Turns a loan repaid over years into a debt due immediately
- Usually sits in the events of default section of the loan agreement
- Banks under the Banking Code generally give small businesses at least 30 days' notice first
- Acting early, before the deadline in the notice, keeps the most options open
Most business loans are repaid a slice at a time. An acceleration clause is the lender’s power to stop the slicing: if the borrower defaults, the remaining balance becomes payable immediately. You will rarely see the word “acceleration” in an Australian contract. Look for wording such as “the balance owing becomes immediately due and payable” in the events of default section.
What usually triggers it
The clause doesn’t act on its own. It relies on a list of defaults elsewhere in the loan agreement. Common ones in business lending:
- a missed or dishonoured repayment
- insolvency, liquidation, administration or bankruptcy
- breaching a loan covenant, such as a minimum interest cover ratio
- selling or encumbering the security without consent
- a change of control or ownership the lender didn’t approve
- a default on another debt (a cross-default)
- information in the application turning out to be false
Some triggers are payment defaults, and the rest are non-monetary. The difference matters, as the next section shows.
Limits on how banks use it
Banks that subscribe to the Banking Code of Practice have accepted extra limits for small business loans. Under the 2025 version, a bank generally won’t act on a non-monetary default unless it falls into a listed category, such as insolvency or another creditor taking enforcement action, and the default is material. Standard form small business loans can’t include a vague “material adverse change” trigger. Before acting, the bank must usually give notice of the default and at least 30 days to remedy it where it can be remedied. Shorter notice is allowed in serious cases.
Separately, Corporations Act provisions in force since 1 July 2018 restrict a lender from enforcing rights only because a company has entered voluntary administration, certain schemes of arrangement or receivership. And in a standard form small business contract, a clause that lets a lender call up the loan for a minor breach could be an unfair term.
Non-bank and private lenders aren’t bound by the bank code, so their notice periods depend on the contract. Read them before you sign.
Worked example
A transport operator borrowed $360k over five years. After three years, $160k is still owing. A large customer collapses, and two repayments are missed. The loan is now in arrears.
Without the clause, the lender could pursue only the missed instalments. With it, after the required notice, the lender can demand the whole $160k, plus default interest and enforcement costs, and then move against the truck and any guarantees.
What changes the outcome is acting in the notice window. The operator could ask for a hardship arrangement, catch up the arrears, or refinance the $160k with another lender that can see the customer loss was a one-off. Once the notice deadline passes, many of those choices shrink.

Frequently asked questions
Is an acceleration clause the same as a default?
No. A default is the event, such as a missed payment. The acceleration clause is what the lender may do about it: call the full balance due. Many loans also charge default interest from the same point.
Can a lender accelerate my loan without warning?
It depends on the lender and the contract. Banks that subscribe to the Banking Code of Practice generally must give a small business notice and at least 30 days to fix a default that can be fixed, with exceptions for serious cases such as insolvency. Non-bank and private lenders follow their own contracts, so read the notice provisions carefully.
What is a cross-default clause?
It lets a lender treat a default on a different loan, sometimes with a different lender, as a default under its own loan. Combined with an acceleration clause, one missed payment elsewhere can put several facilities at risk.
Can an acceleration clause be unfair?
In a standard form small business contract, a term that lets a lender call up the loan for a trivial or unspecified reason could be challenged under the unfair contract terms laws. Since 9 November 2023, unfair terms in these contracts are prohibited and can attract penalties.
What should I do if I receive a notice?
Read what it says must be fixed and by when, then talk to the lender straight away. Ask about a hardship arrangement, and look at refinancing options while there's still time. Getting advice early is far better than waiting for the deadline.
