If you’re struggling to get approved for a personal loan, car loan, or small business finance, one option that may help is having a guarantor or co-signer. This can make lenders more willing to approve your application—even if your credit score is limited or your income is low.
But guarantor loans also come with serious responsibilities, both for the borrower and the person backing the loan.
In this article, we explain how guarantor and co-signer loans work in Australia, their pros and cons, and what you and your family or friends should consider before entering into one.
What Is a Guarantor Loan?
A guarantor loan involves a third party—usually a parent, spouse, or close friend—agreeing to guarantee your loan. This means they promise to repay the loan if you can’t.
These types of loans are often used for:
- Personal loans
- Car loans
- Small business loans
- First home purchases
By reducing the lender’s risk, a guarantor can improve your chances of approval and potentially secure better loan terms.
Guarantor vs. Co-Signer: What’s the Difference?
While the terms are sometimes used interchangeably, there are important differences in Australia:
| Role | Guarantor | Co-Signer |
| Responsibility | Pays only if the borrower defaults | Shares equal responsibility for all payments |
| Control | Not involved in managing the loan | Typically a joint applicant on the loan |
| Risk | Secondary liability | Primary and equal liability |
Most lenders in Australia use the guarantor model, especially for personal and car loans.
Pros of Using a Guarantor for a Loan
✅ Easier Loan Approval
If your credit score is low or you lack a credit history, a guarantor can significantly boost your approval odds.
✅ Access to Better Loan Terms
With a guarantor, lenders may offer lower interest rates, higher borrowing limits, or longer repayment terms.
✅ No Need for a Deposit (in some cases)
For car or business loans, you may not need to provide upfront capital if a guarantor secures the loan.
Cons and Risks of Guarantor Loans
While helpful, guarantor loans carry real consequences.
❌ Risk to Relationships
If the borrower misses payments, the guarantor becomes legally responsible—placing personal relationships under strain.
❌ Impact on Guarantor’s Credit
If repayments fall behind, it can negatively affect the guarantor’s credit file—even if they weren’t managing the loan directly.
❌ Financial Liability
Guarantors may be required to cover the full remaining loan amount, which could involve legal action or asset repossession.
Who Can Be a Guarantor?
In Australia, most lenders will accept a guarantor who is:
- Over 18 years of age
- An Australian citizen or permanent resident
- Financially stable (with income, savings, or assets)
- Not bankrupt or in hardship
Usually, parents, siblings, partners, or close friends act as guarantors—but it’s important they understand the legal and financial implications.
What Should Borrowers and Guarantors Consider?
For Borrowers:
- Will you be able to afford the loan repayments without missing any?
- Is your income stable enough for the full loan term?
- Have you considered alternative options (e.g., lower loan amount or saving a deposit)?
For Guarantors:
- Can you afford to repay the loan if the borrower can’t?
- Are you prepared for the impact on your credit and borrowing capacity?
- Have you sought independent legal advice?
🔎 Tip: Always get loan terms in writing and understand the full conditions before agreeing.
Alternatives to Guarantor Loans
If you’re hesitant about involving family or friends, consider:
- Secured personal loans (using a car or asset as collateral)
- Credit builder loans to strengthen your credit score over time
- Low-doc or alt-doc loans for self-employed applicants
- Working with a finance broker to find flexible lenders
