What cot safety standard applies in Australia?

New household cots sold in Australia must meet the mandatory standard AS/NZS 2172, which covers bar spacing, base strength and the absence of footholds. Check for a compliance label and avoid older drop-side cots.

How firm should a cot mattress be?

Firm and flat. A baby should not sink into it, and it should spring back quickly. It must fit the cot snugly with no more than about a 20mm to 30mm gap around the edges to prevent wedging.

What bedding does a newborn cot need?

Keep it minimal: a correctly fitted sheet and a safe infant sleeping bag. Red Nose guidance is no pillows, bumpers, soft toys or loose bedding in the first year.

What temperature should a nursery be?

Aim for roughly 18 to 22 degrees. Use a room thermometer and adjust the sleeping bag tog rather than adding loose blankets.

Setting up a nursery in a new home is equal parts exciting and overwhelming. The good news is that the essentials are few, and most of the spend that actually matters is about safe sleep, not decor. This checklist covers the decisions that affect a baby's safety and sleep in an Australian nursery: choosing a cot and a firm, correctly fitting mattress, meeting the relevant safety standards, controlling light and temperature, and keeping the room clean. Costs below are 2025 and 2026 Australian pricing.

Things to consider before you choose

Plain practical advice for Australian builds. No fluff.

Cot that meets AS/NZS 2172

In Australia a new cot must comply with the mandatory standard AS/NZS 2172. Check the bar spacing (50mm to 95mm), that there are no footholds, and that the mattress base is sturdy and adjustable in height. Avoid second-hand cots that predate the current standard or have drop-sides.

Firm, correctly fitting mattress

A nursery mattress must be firm and flat, and fit the cot with no more than a 20mm to 30mm gap around the edges so a baby cannot wedge into a space. Firmness matters for safe sleep. A snug, firm cot mattress with a waterproof, breathable protector is the single most important buy in the room.

Safe sleep setup

Follow Red Nose safe sleep guidance: baby on the back, feet to the foot of the cot, no pillows, bumpers, soft toys or loose bedding in the first year. A fitted sheet and a safe infant sleeping bag are all the bedding you need, which also keeps the shopping list short.

Light and temperature control

Blockout blinds or lined curtains help day sleeps and early mornings. Keep the room between about 18 and 22 degrees. In a new, un-shaded estate home a ceiling fan on low helps air movement, and a simple room thermometer takes the guesswork out of layering the sleeping bag.

Storage and the change zone

A low chest with a change mat on top saves buying a separate change table and gives years of use afterwards. Keep nappies, wipes and spare clothes within one arm's reach of the change zone so a baby is never left unattended while you fetch something.

A clean room before baby arrives

New builds shed fine construction dust for weeks, which is worth clearing before a newborn moves in. Give carpets, skirtings and robe tracks a thorough vacuum, and a scheduled robot vacuum keeps the floor clean day to day without you having to drag a vacuum out during nap times.

How much does it cost in Australia?

A safe, functional nursery comes together for roughly $900 to $2,500. The core safe-sleep items are modest: a compliant cot ($250 to $900), a firm fitted cot mattress ($90 to $250) and a waterproof protector ($40 to $90). The rest is storage and comfort: a chest with a change mat ($250 to $700), blockout blinds ($120 to $350 per window), a feeding chair ($200 to $800) and sundries. Spend where safety lives, the cot and mattress, and keep decor cheap and swappable. Buying the mattress and protector direct from a maker with clear firmness specs is usually better value than a bundled nursery package.

Common mistakes to avoid

Using a second-hand cot that predates AS/NZS 2172 or has drop-sides
A cot mattress that leaves a wide gap at the edges
Adding pillows, bumpers or soft toys to the cot in the first year
Leaving the window bare so early light cuts day sleeps short
Setting up before clearing weeks of fine construction dust
