Choosing between treated pine and hardwood is one of the most common questions we hear at our West Gosford workshop. The short answer: hardwood costs more upfront and typically lasts 20 to 30 years outdoors, while treated pine is cheaper to buy but needs replacing every 5 to 8 years in Australian conditions. This article breaks down exactly why that difference matters for your budget, your garden, and your peace of mind.
If you are looking at picnic tables in Australia, you have likely already noticed the price gap between treated pine and hardwood. It is tempting to go with the lower sticker price. But outdoor furniture in Australia faces some of the harshest conditions on earth: UV radiation, summer heat, coastal salt spray, and heavy rain followed by drought cycles. The material you choose determines whether your table lasts a season or a generation.
At Auscraft Furniture, we handcraft Australian hardwood picnic tables from our workshop in West Gosford, NSW. We have been doing this for over 25 years, and we have seen a lot of treated pine tables come and go. This comparison is not a sales pitch. It is the honest guide we wish every buyer had before making the decision.
Cost Comparison: Upfront Price vs Long-Term Value
Treated pine picnic tables typically cost less at purchase, which makes them appealing for tight budgets. A treated pine 6-seater might run $400 to $700 at a hardware chain. A comparable hardwood table from a quality Australian maker sits in the $900 to $1,800 range depending on species and size.
However, the purchase price is only part of the story. Treated pine in Australian outdoor conditions requires re-oiling or re-sealing every 12 to 18 months, and structural degradation (cracking, checking, joint failure) typically begins at the 4 to 6 year mark, with most tables needing full replacement by year 8. Hardwood tables, maintained with a basic oil every 2 to 3 years, remain structurally sound for 20 to 30 years or more.
The table below shows a total cost of ownership comparison for a single outdoor picnic table position over 5, 10, and 20 years.
| Timeframe | Treated Pine (est.) | Australian Hardwood (est.) | Hardwood Saving |
|---|---|---|---|
| 5 years | $600 table + $120/yr maintenance = ~$1,200 | $1,200 table + $60/yr maintenance = ~$1,500 | Pine cheaper short term |
| 10 years | 2 tables + maintenance = ~$2,200 | Same table + maintenance = ~$1,800 | Hardwood saves ~$400 |
| 20 years | 3 to 4 tables + maintenance = ~$4,000+ | Same table + maintenance = ~$2,400 | Hardwood saves ~$1,600+ |
Note: figures are indicative averages. Actual costs vary by product, maintenance regime, and local conditions. Commercial settings (schools, parks, cafes) see even steeper lifecycle differences because of heavier daily use. Request a quote for your specific requirements.
Durability and Weather Resistance
The durability gap between pine and hardwood comes down to wood science. Treated pine is a softwood: it has a lower cell density, larger open pores, and a lower Janka hardness rating. The chemical preservative treatment (typically CCA or ACQ) protects against insects and decay, but it does not change the underlying structural weakness of the wood itself.
Australian hardwoods are a fundamentally different category of material. Species like Spotted Gum and Ironbark are among the densest timbers on the planet. Their tight cell structure naturally resists moisture ingress, checking, and insect attack without any chemical treatment at all.
Janka Hardness: Pine vs Australian Hardwoods
Treated Pine sits at approximately 3.1 kN. Merbau at 8.6 kN. Spotted Gum at 11.0 kN. Ironbark at 14.0 kN. Ironbark is more than four times harder than treated pine by this measure.
Practically, this means a hardwood table will not dent from dropped tools, will not split along the grain when dried by the summer sun, and will not delaminate at joints after rain. In coastal environments, the salt-laden air that rapidly corrodes pine fasteners has minimal effect on a well-built hardwood table with stainless steel hardware.

Appearance Over Time
Both materials change with age, but the way they change is very different.
Treated pine, especially in full sun, bleaches to a pale, washed-out grey within 12 to 18 months. It then begins to develop surface checking (small surface cracks along the grain) and can warp or cup if not kept consistently sealed. By year three or four, a pine table that has not been meticulously maintained looks noticeably tired.
Australian hardwoods age with far more dignity. Left untreated, they silver to a natural weathered grey that many owners find attractive, and they retain their structural integrity while doing so. If you prefer to maintain the original colour, a light application of a quality teak oil or hardwood oil every two to three years is all it takes to keep the table looking rich and warm. Many of our customers report their Spotted Gum or Ironbark tables looking better at ten years old than the day they were delivered, simply because the timber has settled and the colour has deepened.
Best Use Cases: When to Choose Each
Treated pine may suit you if you have a genuinely temporary need (under 5 years), your budget is critically constrained and long-term cost is not a factor, the table will be kept undercover or stored seasonally, or it is for a rental property where low upfront cost matters above all else.
Australian hardwood is the right choice for permanent residential outdoor settings, commercial venues such as cafes, pubs, resorts, and holiday parks, schools, councils, and public parks, coastal properties and high-humidity environments, and anyone who wants to buy once and not again.
For schools and commercial buyers in particular, hardwood is almost always the economically rational choice. A school picnic table that costs $1,400 and lasts 25 years costs $56 per year. A pine table at $650 that needs replacing every 6 years costs $108 per year, plus staff time coordinating replacement and disposal. The numbers are not close.
Auscraft Hardwood Options: Spotted Gum, Ironbark, Merbau and QLD Red Gum
All Auscraft picnic tables are built from premium Australian hardwoods, sourced from responsibly managed forestry operations. Each species has its own character and strengths:
Spotted Gum (Janka 11.0 kN) is one of our most popular species. It has a beautiful wavy grain with golden-brown tones and outstanding dimensional stability, meaning it holds its shape across seasonal temperature and humidity swings. Ideal for high-use residential and commercial settings.
Ironbark (Janka 14.0 kN) is one of Australia's hardest timbers and the species we recommend most often for coastal environments and commercial venues with heavy foot traffic. Its deep red-brown colour is striking, and it has a near-unmatched resistance to weathering.
Merbau has a naturally oily surface that repels moisture without the need for frequent oiling. Its rich dark-brown colour suits contemporary outdoor designs, and it is a consistently popular choice for residential patios and entertainer areas.
QLD Red Gum brings warm reddish tones and strong character grain that makes each table genuinely unique. A quintessentially Australian timber with proven outdoor performance across decades.
All tables are available in standard sizes or can be built to custom dimensions at our West Gosford workshop. Delivery is available across NSW, VIC, and QLD. Request a quote to discuss species availability and lead times for your order, or shop all picnic tables to see what is available now.
What Auscraft Recommends
After more than 25 years building outdoor furniture in Australia, our recommendation is consistent: if your table will be outdoors in Australian weather for more than three years, choose hardwood. The upfront cost difference pays for itself well before the 10-year mark, and you will never deal with the frustration of a failing table at an inconvenient time.
We are not dismissive of treated pine. There are situations where it is the right call, and we have been honest about those above. But we do not build in pine, because our customers come to us for furniture they will not need to think about for decades. That is the commitment we make at every table we build from our West Gosford workshop.
If you are comparing options and want an honest conversation about which species and size suits your specific setting, whether it is a backyard, a school, or a commercial venue, our team is happy to help. There is no obligation, and we will tell you plainly if another option would actually serve your needs better.

Frequently Asked Questions
Is hardwood really worth the extra cost for a picnic table?
Yes, in almost all outdoor Australian settings. Hardwood picnic tables cost more upfront but last 20 to 30 years compared to 5 to 8 years for treated pine. When you factor in the cost of replacement tables and ongoing maintenance, hardwood is significantly cheaper over a 10 to 20 year period. For commercial buyers and permanent residential settings, the return on investment is clear. The only scenario where pine makes financial sense is when the table is genuinely temporary (under 3 years) or will be kept undercover.
How long does treated pine last outdoors in Australia?
In typical Australian outdoor conditions (direct sun, seasonal rain, humidity variation), a treated pine picnic table lasts approximately 5 to 8 years before structural issues such as cracking, joint failure, or significant warping require replacement. Tables that are re-oiled or re-sealed every 12 to 18 months and kept in partial shade may extend toward the upper end of that range. Tables in coastal environments or areas with high UV exposure often degrade faster, sometimes needing replacement at 4 to 5 years.
Which is better for a school: pine or hardwood picnic tables?
Hardwood is the better choice for schools by a significant margin. School picnic tables receive heavy daily use from children and need to withstand knocks, climbing, and constant exposure to weather. Treated pine under commercial use conditions typically requires replacement every 4 to 6 years, and the cost of organising removal and replacement adds to the total. A quality Australian hardwood table from a builder like Auscraft will serve a school for 20 to 25 years with minimal maintenance. Many councils and education authorities now specify hardwood for outdoor furniture for this reason.
Can I get a treated pine picnic table from Auscraft?
Auscraft builds exclusively in Australian hardwoods. We do not offer treated pine tables, as our focus is on furniture built to last for generations. If your budget is currently limited, we are happy to discuss sizing and species options to find an Australian hardwood table that fits. Our entry-level models are priced competitively for the quality of material and craftsmanship, and the long-term value is considerably better than pine alternatives. Contact us to discuss your requirements.
How much more expensive is a hardwood picnic table compared to pine?
At point of purchase, a quality Australian hardwood picnic table typically costs 60 to 120 percent more than a comparable treated pine table. For example, a pine 6-seater might cost $500 to $700, while an Auscraft hardwood equivalent sits in the $1,100 to $1,800 range depending on species and custom requirements. However, over a 10-year period, the hardwood option is typically cheaper in total cost when you account for pine replacement and higher maintenance frequency.
