A NAB business overdraft typically requires financial statements, lodged BAS and a strong credit file, with property security common on larger limits - and approval runs on bank timelines. If NAB declines you, non-bank lenders assess the same business on 6 months of bank statements, with decisions from 1 hour and no property security under $150,000.
NAB runs two paths. QuickBiz, the faster digital product, requires 12+ months trading, GST registration and a minimum $75,000 annual turnover, with unsecured limits up to $150,000. The standard NAB overdraft requires full financial statements and often property security. Current criteria, rates and fees are published on NAB's business overdraft page.
Full-documentation bank overdrafts in Australia typically take 2 to 8 weeks from application to available funds - the process runs through financial statement review, credit assessment and, where security is involved, property valuation and documentation. NAB's digital products move faster where you fit their criteria exactly. By comparison, non-bank lenders through our panel return decisions from 1 hour, with funding same day in many cases and typically within 24 to 48 hours of approval.
Bank overdrafts price in two parts: an interest rate on the overdrawn balance, plus a facility or line fee on the approved limit. Secured bank overdrafts have generally priced in the 8% to 15% p.a. band, materially below unsecured non-bank facilities (14.55% to 25% p.a. through our panel) - the trade-off is the documentation, security and approval time described above. NAB publishes its current business overdraft rates and fees on - always check the live rate there, as bank pricing changes with the cash rate.
NAB's QuickBiz product is faster than their traditional overdraft, but it still has strict criteria: 12+ months trading, GST registration, minimum $75K annual turnover, and a clean credit history. Their standard overdraft requires full financials and often property security.
Common reasons NAB says no:
NAB's QuickBiz goes up to $150K unsecured. But if they decline you, non-bank lenders can offer the same amount with lower entry requirements - from 6 months trading and $6K/month revenue.
Through OverdraftMe, you access 50+ non-bank lenders who assess on bank statements alone. No tax returns, no BAS, no financial statements under $150K. Many of our clients come to us after a NAB decline and are funded within 24 hours.

Yes - NAB's QuickBiz product offers unsecured overdrafts up to $150,000 for businesses with 12+ months trading and $75,000+ annual turnover (check current criteria on NAB's page). If you fall short of those thresholds, non-bank lenders approve unsecured facilities from 6 months trading and $6,000 monthly revenue.
Full-documentation bank overdrafts typically take 2 to 8 weeks; NAB's digital products are faster where you fit the criteria exactly. Non-bank lenders through OverdraftMe return decisions from 1 hour, with funding typically within 24 to 48 hours of approval.
Expect to provide financial statements, up-to-date tax returns, lodged BAS and clear director credit files, with property security common at higher limits. Non-bank lenders need 6 months of business bank statements, an ABN and a driver's licence - no tax returns under $150,000.
Don't apply to another major bank - the criteria are similar and each application adds a credit enquiry. Through OverdraftMe, one application is matched against 50+ non-bank lenders who assess on bank statements, with decisions from 1 hour.
