Best Thermometers for Home Use in Australia (2026)
At a Glance
Ear thermometers offer the best balance of speed and accuracy for families with children. A basic digital stick thermometer is perfectly reliable for adults and costs under $20.
Braun ThermoScan 7 Ear Thermometer
Omron MC-246 Digital Thermometer
A reliable thermometer is one of the most important items in any home first aid kit. Whether you are monitoring a sick child overnight or checking your own temperature before calling in to work, an accurate reading helps you decide what to do next — rest at home, take paracetamol, or seek medical attention.
The awkward bit is choosing one before you urgently need it. There is a big jump in price between a basic digital thermometer and a premium ear or infrared model, and the marketing does not always make it obvious what you are paying for. We compared the common home options by accuracy, speed, ease of use, and everyday practicality.
The Bottom Line
For most families, a quality ear thermometer like the Braun ThermoScan 7 offers the best combination of speed, accuracy, and ease of use — particularly with young children. If you are on a budget, a simple digital stick thermometer does the job reliably for adults and older children.

Types of Thermometers Available in Australia
Mercury thermometers have been phased out for safety reasons. Modern home thermometers fall into four main categories, each with different strengths and trade-offs.
Digital Oral/Underarm Thermometers
The classic stick-style thermometer with a metal tip and digital display. Place it under your tongue (oral) or in the armpit (axillary) and wait for the beep — usually 30 to 60 seconds. These are the most affordable option and provide reliable readings when used correctly. They are best suited to adults and children old enough to hold the thermometer still under their tongue.
Ear Thermometers (Tympanic)
Ear thermometers use an infrared sensor to measure heat emitted by the eardrum (tympanic membrane), which closely reflects core body temperature. They deliver a reading in 1 to 3 seconds, making them excellent for children who will not sit still. Most models require disposable probe covers, which add a small ongoing cost. Not recommended for babies under 6 months, as their ear canals are too narrow for accurate readings.
Forehead Thermometers (Temporal Artery)
These infrared devices scan across the forehead or temple area. Some require skin contact; others work from a few centimetres away. They are fast (1 to 2 seconds) and non-invasive, which makes them convenient for sleeping babies. However, external factors like sweating, ambient temperature, and technique can affect accuracy more than with ear or oral methods.
Non-Contact Infrared Thermometers
Popularised during COVID-19 for screening purposes, these devices measure forehead temperature from several centimetres away. They are the most hygienic option as nothing touches the skin, and many can also measure surface temperatures of objects like baby bottles. The trade-off is that they tend to be the least accurate of the four types for clinical-grade body temperature measurement.
Thermometer Types Compared
| Type | Accuracy | Speed | Price Range | Best For |
|---|---|---|---|---|
| Digital oral/underarm | High (oral); moderate (underarm) | 30–60 seconds | $10–$30 | Adults, older children, budget buyers |
| Ear (tympanic) | High | 1–3 seconds | $40–$120 | Families with children over 6 months |
| Forehead (temporal) | Moderate to high | 1–2 seconds | $30–$80 | Sleeping babies, quick checks |
| Non-contact infrared | Moderate | Under 1 second | $40–$100 | Screening, hygiene-sensitive settings |

How to Take Temperature Correctly
Even the best thermometer will give unreliable results if you use it incorrectly. Here is how to get the most accurate reading from each method.
Oral (Under the Tongue)
- •Wait at least 15 minutes after eating, drinking, or exercising.
- •Place the tip under the tongue, towards the back, and close your mouth.
- •Breathe through your nose and keep still until the thermometer beeps.
- •Normal oral temperature is around 36.8 degrees Celsius, but anywhere from 36.2 to 37.2 degrees is considered normal.
Ear (Tympanic)
- •Use a clean probe cover for each reading.
- •For adults and children over 1 year: gently pull the ear up and back to straighten the ear canal.
- •For children under 1 year: gently pull the ear straight back.
- •Insert the probe snugly into the ear canal and press the button.
- •Wait for the beep. Do not move the thermometer during measurement.
- •Avoid using immediately after the person has been lying on that ear — wait 5 minutes.
Forehead / Non-Contact
- •Ensure the forehead is dry — wipe away sweat before measuring.
- •Hold the thermometer at the distance specified in the instructions (usually 3 to 5cm).
- •Keep the person out of direct sunlight or away from heaters before measuring.
- •For contact forehead thermometers, swipe smoothly across the forehead from the centre to the temple.
- •Indoor temperature extremes can affect readings — let the person acclimatise for a few minutes if they have just come inside.
Underarm (Axillary)
- •Place the tip in the centre of the armpit, with the arm pressed firmly against the body.
- •Hold for the full measurement time (often 3 to 5 minutes for underarm).
- •Underarm readings tend to be 0.5 to 1.0 degrees lower than oral readings.
- •This method is the least accurate but can be useful for very young children or people who cannot use oral or ear methods.
Consistency Matters
Whatever method you choose, stick with it. Comparing an oral reading from this morning with a forehead reading tonight will not give you a reliable picture. Use the same thermometer, the same method, and ideally the same time of day when tracking a fever.
When Is a Fever? Temperature Ranges Explained
Normal body temperature varies between individuals and throughout the day — it is typically lowest in the early morning and highest in the late afternoon. The following ranges are general guides based on oral measurement. Ear readings are similar to oral; underarm readings tend to be about 0.5 degrees lower.
Adults
| Reading | What It Means |
|---|---|
| 36.2–37.2°C | Normal range |
| 37.3–38.0°C | Low-grade fever (elevated temperature) |
| 38.1–39.0°C | Moderate fever |
| 39.1°C and above | High fever — seek medical advice |
Children
| Reading | What It Means |
|---|---|
| 36.5–37.5°C | Normal range |
| 37.6–38.0°C | Mildly elevated — monitor and keep child comfortable |
| 38.1–38.5°C | Moderate fever — consider paracetamol or ibuprofen if child is uncomfortable |
| 38.5°C and above | High fever — see your GP or call healthdirect on 1800 022 222 |
Babies Under 3 Months
Any temperature of 38.0 degrees Celsius or above in a baby under 3 months is a medical emergency. Take your baby to the nearest emergency department immediately, even if they appear otherwise well.
When to See a Doctor with a Fever
Most fevers in otherwise healthy adults and older children resolve on their own within a few days. However, you should seek medical attention in the following situations:
- •Any fever in a baby under 3 months old — go to the emergency department immediately.
- •Fever above 38.0 degrees Celsius in a baby aged 3 to 6 months — see a doctor the same day.
- •Fever above 39.0 degrees Celsius in adults that does not respond to paracetamol or ibuprofen.
- •Fever lasting more than 3 days in adults or more than 24 hours in children under 2 years.
- •Fever accompanied by a stiff neck, severe headache, rash, difficulty breathing, persistent vomiting, or confusion.
- •Fever in anyone with a weakened immune system, chronic illness, or who is undergoing cancer treatment.
- •Febrile seizures (fits associated with fever) in children — call 000 if the seizure lasts more than 5 minutes.

What to Look For When Buying a Thermometer
- •Match the type to the user: Ear and forehead thermometers are best for young children. Digital stick thermometers are fine for adults.
- •Age Precision or fever indicators: Colour-coded displays (green/yellow/red) save you from Googling fever ranges at 3am. Worth the premium if you have young children.
- •Backlit display: Essential if you are checking a child's temperature in a dark bedroom overnight.
- •Memory function: Useful for tracking whether a fever is rising or falling over several hours.
- •Ongoing costs: Ear thermometers require disposable probe covers ($8 to $12 per 40). Digital and forehead thermometers generally have no ongoing costs beyond battery replacement.
- •Speed: If you are measuring a squirming toddler, a 1-second ear reading beats a 60-second oral reading every time.
- •Brand reputation: Stick to established medical device brands like Braun, Omron, and Vicks. Avoid unbranded imports with no TGA listing or Australian warranty.
Frequently Asked Questions
Which type of thermometer is most accurate for home use?
For home use, digital oral thermometers and ear (tympanic) thermometers are generally the most accurate. Oral thermometers are considered the gold standard for adults when used correctly. Ear thermometers are extremely accurate when positioned properly and are more practical for children. Forehead and non-contact thermometers trade a small amount of accuracy for convenience.
Are non-contact thermometers accurate enough?
Non-contact infrared thermometers are useful for quick screening and checking sleeping children, but they can be affected by ambient temperature, sweating, and distance. They are accurate enough to detect a significant fever but may not give precise readings for borderline temperatures. If a non-contact reading seems elevated, confirm with an oral or ear thermometer.
Can I use an ear thermometer on a baby?
Ear thermometers are not recommended for babies under 6 months because their ear canals are too narrow to get an accurate reading. For babies under 6 months, a digital underarm (axillary) measurement or a forehead thermometer is more appropriate. For any fever in a baby under 3 months, seek immediate medical attention regardless of the method used.
Why do I get different readings from different thermometers?
Different measurement sites have different normal ranges. Oral and ear readings are generally similar. Underarm readings tend to be 0.5 to 1.0 degrees Celsius lower, while forehead readings can vary depending on technique and environmental factors. This is normal — the key is to use the same method consistently and know the normal range for that method.
How often should I replace my thermometer?
Most digital thermometers last 3 to 5 years with normal use. Replace your thermometer if the display fades, if it gives clearly inaccurate readings (for example, if your known-well temperature reads significantly outside normal range), or if the battery compartment corrodes. Store it in a clean, dry place between uses.
Do I need to calibrate my home thermometer?
Consumer-grade thermometers do not typically require calibration. However, you can check accuracy by taking three readings in a row — they should be within 0.2 degrees of each other. If results vary wildly, the thermometer may be faulty. Some pharmacies offer accuracy checks if you bring your thermometer in.
