The size of the deck greatly affects the cost. A small deck, about 10 square metres, can cost between $3,000 and $5,500. On the other hand, a big deck of 50 square metres or more might cost from $5,900 to $11,500 or more.

In Australia, councils have rules for deck size. You usually need approval for decks over 10 square metres. Also, decks can't be more than 600mm tall before needing more approval. The bigger and more complex the deck, the more it will cost for materials and work.

• Smaller 10 square metre decks can cost $3,000-$5,500
• Larger 50 square metre+ decks can range from $5,900-$11,500+
• Councils typically require approval for decks larger than 10 square metres
• Deck heights are often limited to 600mm before further approval is needed
• Larger and more complex deck designs lead to higher material and labour costs

The size of the deck is key to the project's cost. Homeowners should think about their space, council rules, and budget when planning their deck's size and design.
