Treated pine ($160–$315/sqm in Hobart) is cheapest but needs regular oiling. Merbau ($270–$495/sqm) and spotted gum are premium hardwoods. Composite ($250–$495/sqm) is low-maintenance.
Deck size
A small 15 sqm deck in Hobart costs $4,500–$9,000. Medium 25 sqm is $7,200–$14,400. Large 40 sqm decks run $11,700–$23,400. Larger decks get slightly better per-sqm rates.
Height & subframe
Ground-level decks in Hobart are simplest. Elevated decks (over 1m) need substantial substructure, posts, and often engineering — increasing costs significantly.
Steps & balustrades
Steps cost $135–$360 per step in Hobart. Balustrades/railings add $120–$350/lm. These are required by code for any deck over 1m above ground.
Site access & slope
A flat, accessible Hobart backyard is cheapest. Sloping sites, difficult access, or existing structures to build around all increase labour time and cost.
Maintenance requirements
Hardwood decks need oiling 1–2 times per year (DIY $50–$100, professional $22–$54/sqm in Hobart). Composite decking needs almost no maintenance — a hose-down is usually sufficient.
How to Save Money on Decking in Hobart
1
Get quotes from licensed Hobart deck builders — make sure each quote includes the same timber species and subframe specifications
2
Consider composite decking if low maintenance is a priority — it costs similar to hardwood upfront but saves on annual oiling
3
Check your Hobart council for permit requirements — decks over a certain height or size may need a building permit
4
Ask about the subframe — a quality subframe (often the biggest cost component) determines how long the deck lasts
5
Factor in ongoing maintenance costs — a hardwood deck in Hobart costs $200–$500/year to maintain; composite costs almost nothing
6
Ask about drainage under the deck and how the structure connects to your house — waterproofing the connection point is critical
Frequently Asked Questions
How much does decking cost per sqm in Hobart?

How much does a 20 sqm deck cost in Hobart?

Is composite decking worth the extra cost?

How long does a timber deck last?
Treated pine decks last 15–20 years with regular maintenance. Hardwood (merbau, spotted gum) lasts 25–40+ years. Composite decking lasts 25–30 years with minimal maintenance.
How long does it take to build a deck in Hobart?
A standard deck (15–25 sqm) in Hobart takes 3–7 days to build. Larger or more complex decks with pergolas, steps, and balustrades can take 2–3 weeks.
