Will I have to pay more because I am a casual employee?

Not necessarily, but in practise, probably. As a casual worker you will most likely be deemed as riskier and so have less access to the lowest-cost products. However, if you have a long, clean record of borrowing and repaying money, an existing relationship with a bank and a decent income from casual work, you very well could be approved for a no fee, low rate loan.

What if I work for multiple employers casually?

Having multiple jobs is not necessarily a bad thing in terms of getting a car loan. In one way, it makes you a less risky customer as you have a more diversified income. You will need to prove your total income and all your places of employment. Having a long history of regular hours and income will help.

What will happen if I stop working?

You are required to pay back your loan, regardless of your employment status. Make sure you have a little bit of extra money to make the minimum repayments should you lose your job. Most lenders have some kind of financial hardship provision, so you should talk with your lender straight away if you think you will not be able to make a repayment.
