The compliance rules behind a deck balustrade
A balustrade on a raised deck is a safety barrier, and the National Construction Code sets hard numbers. If the deck surface is more than 1 metre above the ground, the balustrade must be at least 1 metre high. The openings in it must not allow a 125 millimetre sphere to pass through - so vertical balusters, wire spacing or panel gaps all have to stay under 125 millimetres.
On a deck that forms part of a pool fence, the rules tighten further: the non-climbable zone applies, meaning no horizontal rail or feature can act as a foothold for a small child climbing the barrier. A balustrade chosen on looks alone, without these numbers in mind, fails inspection.
Timber, wire and glass - and why fixing matters
Timber balustrades suit heritage and traditional homes and are the most economical. Stainless wire balustrades are popular in Adelaide for preserving a view - but wire has to be tensioned correctly and spaced so it cannot be spread past 125 millimetres, which is a genuine compliance and workmanship detail. Glass balustrades give the cleanest look and the clearest view, cost the most, and have their own fixing and panel-strength requirements.
Whatever the style, the balustrade is only as good as its fixing. The posts carry the load of someone leaning or falling against the rail, and posts that are under-fixed or fixed into a weak part of the frame work loose over time. A licensed builder fixes balustrade posts properly into the structure - it is the difference between a rail that holds and a rail that wobbles.

Handrails & Balustrading - frequently asked questions
If the deck surface is more than 1 metre above the ground, the National Construction Code requires the balustrade to be at least 1 metre high. The openings must not allow a 125 millimetre sphere to pass through, so balusters, wire or panel gaps all stay under 125 millimetres. A deck that forms part of a pool fence has additional non-climbable-zone rules.
It depends on the home and the priority. Timber suits heritage and traditional homes and is the most economical. Stainless wire preserves a view and is popular in Adelaide, but must be tensioned and spaced correctly to stay compliant. Glass gives the clearest view and the cleanest look at the highest cost. All three are compliant when built right.
Because the posts were under-fixed or fixed into a weak part of the frame. A balustrade post carries the load of someone leaning or falling against the rail, so it has to be fixed properly into solid structure. A post fixed with too few bolts, or into a thin or rotting member, works loose over time. Correct fixing is what keeps a rail solid.
Timber balustrading runs $220 to $340 per linear metre, stainless wire $280 to $420, and glass $350 to $480, in metro Adelaide for 2026. Deck height, post material and any pool-zone requirements move the figure. It is best quoted as an itemised line within the overall deck quote.
Avoid the cash-only cowboy
The biggest decking risk in South Australia is an unlicensed, cash-only builder. With no BWC licence there is no building indemnity insurance, no recourse through CBS or SACAT if the work fails, and your house insurance can decline rot or structural claims tied to unlicensed work. Here is how to tell the two apart.
Walk away if
- Cash only, no written contract, no GST invoice
- Cannot give a BWC licence number to check
- Wants a deposit well above the 5% legal cap
- Quotes a single lump sum with no itemised breakdown
A real builder has
- Current BWC licence, verifiable on the CBS register
- Written contract and building indemnity insurance over $20,000
- Deposit at or under the 5% legal cap
- Itemised quote - frame, boards, fixings, finish, balustrades
