Composite decking is the better fit for most Pakenham family decks, but not every block
Composite costs more upfront, usually $380-$580 per m2 installed, but it avoids regular oiling and suits busy households. Timber is still the right call when budget is tight, the deck is shaded, barefoot heat matters, or a hills home needs a natural BAL-aware specification.
Side-by-side comparison for local homes
| Decision point | Timber decking | Composite decking |
|---|---|---|
| Upfront cost | Treated pine $220-$320 per m2. Merbau or common hardwood $280-$420 per m2. Premium hardwood can sit higher. | Usually $380-$580 per m2, depending on board range, fixings, edge boards and ventilation detail. |
| Lifespan | 12-15 years for treated pine, 20-30 years for maintained hardwood on a good frame. | Often 20-25 year product warranty, but still depends on frame, drainage and correct installation. |
| Maintenance | Wash and oil every 12-24 months. Budget $12-$25 per m2 for oiling or $35-$65 per m2 for sanding when neglected. | Wash as needed. No oiling, but scratches, heat marks and poor ventilation can still cause issues. |
| Local conditions | Handles heat well under bare feet. Needs care in damp shade, leaf litter and around garden beds. | Strong choice for exposed Pakenham and Officer alfresco areas. Dark colours can get hot in afternoon sun. |
| Bushfire and hills blocks | Some hardwoods suit BAL-aware design, subject to assessment and detailing. | Some systems may suit BAL requirements, but product certification and installation details matter. |
| Resale | Natural look can suit established Beaconsfield and hills homes if maintained. | Low-maintenance selling point for modern family homes, rentals and busy households. |
Our recommendation: choose composite for most new Pakenham and Officer family decks if the budget can handle the premium, especially where you want a clean outdoor area without annual oiling. Choose timber if you want the lowest upfront price, prefer a natural finish, have a shaded hills setting, or need a specific BAL-rated hardwood detail after assessment.
The real cost difference over 10 years
Upfront price is only the first line. Take a 30 m2 deck behind a Pakenham brick veneer home. A merbau deck at $350 per m2 might be $10,500 before extras. A composite deck at $480 per m2 might be $14,400. The first quote is $3,900 cheaper, which matters if you are building to a tight budget.
Now add maintenance. If timber oiling costs $18 per m2 every 18 months, that is about $540 each time. Over 10 years, five or six oiling cycles can add $2,700-$3,240, and one sand at $45 per m2 adds another $1,350 if the deck is neglected. That does not make timber bad. It means the cheaper deck needs an owner who will maintain it.
Composite does not eliminate every cost. It still needs washing, correct ventilation and careful detailing. It can mark if a barbecue is dragged across it, and poor installation can void the product warranty. But for a busy family that wants to spend weekends using the deck rather than oiling it, composite is usually the lower-hassle choice.

Pakenham and Officer growth-area homes often have open rear yards, concrete alfresco slabs, newer brickwork and afternoon sun. Composite performs well in that setting because the owner usually wants a neat outdoor extension with low maintenance. Add a pergola or shade sail and darker composite becomes more comfortable.
Beaconsfield, Beaconsfield Upper, Pakenham Upper, Cockatoo, Emerald and Gembrook have more slope, vegetation and shade. Timber feels more natural in those settings and is often easier to blend with older homes, acreage gardens and rural-style verandas. The catch is maintenance. Leaf litter and damp shade punish neglected timber, so the design needs airflow and a realistic oiling plan.
Heat is the issue homeowners notice too late. Composite, especially dark composite, can be uncomfortable in full summer sun. If the deck is a barefoot path to a pool or kids play space, ask to see physical samples in sunlight, not just a brochure. Timber is not cool, but it often feels kinder underfoot than dark composite.
For bushfire areas, do not choose from instinct. Read the permit and BAL guide and get the address checked. BAL compliance is a system, not a single board. Subfloor enclosure, ember gaps, adjacent walls and vegetation all affect the answer.
When timber is the better call
Pick timber when the budget is under about $12,000 for a modest deck, when the owner is willing to oil it, or when the home would look wrong with a manufactured board. A small merbau landing, a rural veranda, a shaded cottage deck in Emerald or a natural hardwood entertainment area can all be excellent timber jobs.
Timber is also easier to repair invisibly. One damaged board can be replaced, sanded and blended. On an old composite deck, colour matching can be harder because boards fade over time and product ranges change. For owners who like doing maintenance and want a warm natural finish, timber is not second best. It is the right material.
The honest constraint is maintenance. If you know you will not oil the deck, do not buy timber because the quote is cheaper. The saving disappears when the boards go grey, cup and splinter. At that point you are reading the spongy deck board guide and pricing repairs.
When composite is the better call
Pick composite when low maintenance is the main brief, when the deck is part of a modern alfresco, when resale presentation matters, or when the owner does not want annual oiling. Composite works particularly well beside alfresco outdoor kitchens, where oiling around appliances, cabinets and furniture is inconvenient.
Composite also suits rental properties and busy households. It does not need the same seasonal care routine, and it can keep a consistent appearance with washing. The frame still needs to be right: straight joists, correct spacing, ventilation, drainage and manufacturer-compatible fixings. The cheapest composite install is not the best composite install.
