Building a new home in Australia typically costs $1,500–$4,500 per square metre depending on location, design, and finishes. A standard 200m² home ranges from $300,000–$900,000 including site costs but excluding land.
Labour costs, material transport, local council requirements, and demand all affect pricing. NSW and VIC typically have the highest construction costs due to higher labour rates and land values.
All quotes from registered businesses must include GST. Always confirm whether quotes are GST-inclusive or exclusive. For projects over $1,000, a written contract is recommended.
