Buying a house is a major investment and a complex process in Australia. Here are some basic steps you should follow when buying a house in Australia:

1. Determine your budget: The first step is to determine your budget. Consider your current income, expenses, and debts to determine what you can afford. You may also need to consider additional costs like stamp duty, legal fees, and building and pest inspections.
2. Find a property: Once you have determined your budget, start looking for properties that meet your needs and budget. You can search online, attend open houses, or work with a real estate agent.
3. Conduct inspections: Once you find a property you like, conduct a building and pest inspection to identify any structural issues or pests that may require costly repairs. If necessary, you may also need to conduct additional inspections, such as strata reports or land surveys.
4. Make an offer: If you are satisfied with the property and the inspections, make an offer to the seller. Negotiate the price and other terms of the sale, such as the settlement date.
5. Obtain finance: If your offer is accepted, obtain finance from a lender. You will need to provide documentation like pay slips, bank statements, and tax returns to support your loan application.
6. Sign a contract: Once your finance is approved, sign a contract with the seller. The contract should include details like the purchase price, settlement date, and any conditions of the sale.
7. Settlement: On the settlement date, the property ownership will transfer to you, and you will need to pay the balance of the purchase price. The settlement process can take several weeks, and you may need to work with a conveyancer or solicitor to complete the process.

Remember, buying a house is a significant investment, and it is essential to do your due diligence and seek professional advice to ensure the process goes smoothly.
