Deposit a cheque in an alternative name into a personal bank account (Australia)
You actually don't have to open a business account with your bank, you can have a personal account with the bank and have your business funds go into it, whether it be from cheques or from Eftpos\Credit Card Facilities. You just have to get your customers to make the cheque out under your name (the same name used for your bank account). If you are trading as a sole trader and you trade under a name other than your own name, then officially you are supposed to register that name with Fair Trading in your state. However, if you are trading using another name and it is not registered, Fair Trading will only become aware of it if someone (usually one of your customers) makes a compliant about you, and they will then ask you to either stop using that name as your trading name or have it registered (if not already registered by someone else).
