This facility is one of the most useful financial tools available to an Australian small business. It is also one of the most frequently misused.
Used correctly, it smooths out the timing gap between costs and revenue, reduces the stress of irregular cash flow, and allows the business to act quickly on opportunities without a new application cycle each time. Used poorly, it becomes permanent debt that masks a structural problem the business needs to address differently.
The difference between these two outcomes comes down to understanding what the product is actually designed for.
How a Business Line of Credit Works in Australia
This product establishes an approved credit limit the business can draw against as needed. Unlike a term loan, there is no requirement to draw the full amount at the start. Unlike a credit card, limits are typically much larger and the product is assessed and structured for commercial use.
Here is how the mechanics work in practice.
A business is approved for a $150,000 line of credit. In month one, a large client invoice is delayed by three weeks and the business needs $40,000 to cover payroll. It draws $40,000. Interest accrues on the $40,000 outstanding, at the agreed rate, for the period it is drawn. When the client invoice is paid, the business repays the $40,000 plus accrued interest. The limit resets to $150,000.
In month three, the business wins a new contract and needs to purchase $85,000 of materials before the first progress payment arrives. It draws $85,000. Interest accrues on that balance. As progress payments arrive, the business repays the facility in portions, reducing the interest cost as each repayment is made.
Interest accrues only on the outstanding drawn balance at any given time. A business that never draws on the facility pays no interest. A business that draws $50,000 for 20 days pays interest on $50,000 for 20 days only.
Business Line of Credit vs Business Overdraft
Both products serve similar purposes, but they differ in structure and how they sit in the business's banking arrangement.
A business overdraft is typically attached to the business's transaction account. The account can operate in a negative balance up to the approved limit. Interest applies to the overdrawn balance. Overdrafts are the simplest working capital product banks offer and are most suited to smaller, regularly fluctuating cash needs.
A standalone credit line is a separate facility separate from the transaction account. Funds are drawn into the transaction account as needed. This separation makes the facility more flexible: it can be accessed at any time, from any bank account, without the business needing to operate its main account below zero.
Bank overdrafts carry the lowest rates, require established banking relationships, and are typically capped at lower amounts. A non-bank revolving facility lender may carry a higher rate but is accessible earlier, available without an existing banking relationship, and offered at larger limits.
For most small businesses, the two products are functionally similar for amounts under $50,000. For amounts above $50,000, or where the business needs to separate its working capital facility from its operating account, a standalone line of credit is the cleaner structure.
Who a Business Line of Credit Suits
A revolving credit facility is the right choice for specific business profiles and situations.
Businesses with irregular but predictable cash flow cycles. A seasonal business that receives the majority of its annual revenue in four months needs to fund operations in the other eight. A line of credit drawn in the lean months and repaid in the peak months manages this cycle efficiently.
Service businesses operating on extended payment terms. A business that invoices at project completion and waits 45 to 90 days for payment has a consistent timing gap between when work is done and when cash arrives. A line of credit bridges that gap without requiring a new application each time a large project is completed.
Businesses that want flexibility for opportunistic purchases. A supplier offers a bulk discount available for 48 hours. A competitor's client base becomes available due to that competitor closing. A piece of equipment comes up at auction for 60% of market value. A line of credit lets the business act on time-sensitive opportunities that a standard loan application cycle would miss.
Businesses managing multiple project timelines simultaneously. Construction, professional services, and consulting businesses often have several concurrent projects at different payment stages. A line of credit smooths the aggregate cash position across all projects rather than requiring separate facilities for each.
This product is less suited to funding capital investment. Equipment purchases, property acquisition, and business acquisitions all involve long-life assets whose cost should be matched against their revenue contribution over time through a term loan structure. Drawing on a revolving credit facility for a capital investment creates a balance that should not cycle down, which undermines the product's fundamental logic.
What Lenders Assess for a Business Line of Credit Application
This facility is assessed against the same framework as other commercial lending, with particular focus on how the business generates and manages cash flow.
Cash flow serviceability. The lender calculates whether the business generates enough surplus cash, after all existing obligations, to service the worst-case scenario of the facility fully drawn for an extended period. Most lenders stress-test the facility at full utilisation even though day-to-day usage will be partial and revolving.
Conduct on existing credit. A business with clean conduct on existing facilities, no dishonours, and consistent ATO lodgements is a stronger line of credit candidate than one with a history of running close to credit limits or carrying irregular account conduct.
Revenue pattern. Lenders want to understand the revenue cycle the line of credit is designed to serve. An annotated bank statement showing when revenue arrives, when costs fall due, and what the timing gap between them looks like gives the lender a clear picture of why the facility is needed and how it will cycle.
Trading history. Most bank lenders require a minimum of 12 to 24 months of trading before establishing a line of credit. Non-bank lenders work from six months for smaller facilities. The limit approved typically reflects a multiple of average monthly revenue rather than a fixed amount.
The Most Important Practical Advice: Apply Before You Need It
This point applies to all working capital finance and particularly to lines of credit.
A business that applies for a line of credit from a position of operational stability, adequate revenue, and no immediate crisis is assessed very differently from one that applies because the bank account is at zero and payroll is due in four days.
Lenders read the urgency in a distressed application. A business that has been operating for two years, is profitable, and wants to establish a line of credit as a prudent financial management tool is a straightforward application. A business applying because it is in crisis is a risk-elevated application, regardless of the underlying financial position.
The line of credit is most valuable as a facility established when it is not urgently needed, available and ready when the business does need it. Setting it up six months before a seasonal trough or a growth phase, not during one, is how the product provides its maximum benefit.

Frequently Asked Questions
How does a business line of credit differ from a term loan?
A line of credit is revolving: draw what you need, repay as cash arrives, draw again as needed. Interest applies only to the outstanding balance. A term loan provides a fixed lump sum that is repaid in set instalments over a defined period. Once repaid, the term loan is closed. A line of credit is designed for recurring, variable cash flow needs. A term loan is designed for specific, bounded capital needs. Using a term loan for ongoing working capital creates unnecessary fixed obligations. Using a line of credit for a capital investment creates a balance that should not cycle down.
What is the maximum credit limit available for a business in Australia?
Maximum limits vary by lender and business profile. Bank business overdrafts typically cap at $250,000 to $500,000 for established businesses. Non-bank lines of credit range from $10,000 to $2,000,000 depending on revenue, serviceability, and security. For most small businesses, the approved limit is calculated as a multiple of average monthly revenue, typically one to three months. Businesses with stronger credit profiles and property security can access higher limits.
Does this type of facility require security in Australia?
Bank business overdrafts frequently require security, often in the form of a registered mortgage or a fixed and floating charge over business assets. Non-bank lines of credit are commonly available unsecured up to $150,000 to $250,000. Larger unsecured facilities require stronger financial positions to compensate for the absence of collateral. Most facilities, secured or not, require a director personal guarantee.
What happens if I draw the full limit of my line of credit and cannot repay quickly?
A line of credit at its maximum limit for an extended period suggests the facility is covering a structural cash flow problem. Our article on business cash flow finance helps distinguish between timing gaps and structural issues. rather than a timing gap. If this happens, the most useful first step is to assess whether the underlying business generates sufficient revenue to eventually repay the balance, or whether the facility is masking a more fundamental issue. Speak to your broker or accountant. A facility that cannot be reduced over time requires a business response, not another financial product.
Can I increase my line of credit limit?
Yes. Most lenders review facilities periodically and can approve limit increases where the business's financial position supports a higher amount. A request to increase a limit is assessed similarly to a new application: current financial statements, bank statements, and evidence of how the existing facility has been used. A business that has drawn and repaid a line of credit cleanly over 12 months is a strong candidate for a limit increase.
