Best Thermometers Australia (2026): Ear, Forehead & Digital

A reliable thermometer is one of the most important items in any home first aid kit. Choosing the best thermometer in Australia comes down to who you are measuring and how fast you need a reading. 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.

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

Accuracy by Method: What to Expect

Accuracy depends as much on the measurement method as on the brand. As a general guide based on the published specifications of consumer medical devices: a good digital probe thermometer is typically accurate to within about 0.1°C, ear (tympanic) thermometers are similarly close to core body temperature when positioned correctly, and forehead or non-contact infrared thermometers show more variance — readings can drift if the skin is sweaty, if the person has just come in from the cold or sun, or if the ambient room temperature is unusually warm or cool. This is why oral and ear methods are generally preferred when precision matters, and why a borderline forehead reading is worth confirming with one of those methods.

Our Top Picks: The Best Thermometer Australia Has to Offer

Best Overall: Braun ThermoScan 7 Ear Thermometer

The Braun ThermoScan 7 is the easiest premium thermometer to recommend for family use. It is quick, easier to interpret than a plain number-only display, and far less of a struggle with kids than a stick thermometer under the tongue or arm. The Age Precision feature is genuinely helpful, especially when you are half-awake and just want to know whether the reading is reassuring or not. Braun has since released an updated model, the ThermoScan 7+, which carries the same core infrared technology and Age Precision display — if you are buying new, it is worth checking whether the 7+ is available and similarly priced.

Best Budget Ear Thermometer: Braun ThermoScan 3

If you want the reliability of an ear thermometer at a lower price, the Braun ThermoScan 3 is a solid entry-level option. It delivers a 1-second reading and has an audio fever indicator that beeps differently depending on the temperature range. It lacks the colour-coded Age Precision display of the ThermoScan 7, but the core infrared measurement technology is the same.

Best Forehead Thermometer: Braun No Touch + Forehead

The Braun No Touch works in two modes: hold it up to 5cm from the forehead for a no-contact reading, or touch it gently to the forehead for a contact reading (which tends to be slightly more accurate). The guidance system uses lights to help you position it at the correct distance. It also features Age Precision and a colour-coded fever display, similar to the ThermoScan 7.

Best Non-Contact: Vicks Non-Contact Infrared Thermometer

The Vicks Non-Contact Infrared Thermometer is a straightforward, well-priced option for non-contact temperature checks. Its Fever InSight feature uses a colour-changing display (green, yellow, red) so you can instantly understand the reading. It works from about 3 to 5 centimetres from the forehead and also measures surface temperatures — handy for checking bath water or baby bottles.

Best Digital Stick: Braun Digital Thermometer

The Braun Digital Thermometer is a reliable, no-fuss option for oral or underarm use. It features a flexible tip for comfort, a fever beep alert, and a waterproof design that makes it easy to clean. Most readings are ready within 60 seconds. For adults and older children who can hold a thermometer still under their tongue, a quality digital stick like this is all you need.

Best Value: Omron MC-246 Digital Thermometer

The Omron MC-246 is a budget-friendly digital thermometer from a trusted medical device brand. It offers a flexible tip, fever alarm beep, and a clear digital display. It does what a basic thermometer needs to do — measure temperature accurately — without any bells and whistles. If you just need a reliable thermometer in the medicine cabinet, this is the one.

Also Worth Considering: Beurer FT65 (3-in-1)

If you want one device that covers multiple methods, the Beurer FT65 is a 3-in-1 thermometer that can take forehead, ear, and surface (object) temperatures. A multi-mode device can be convenient for households measuring people of different ages, though combination units involve some trade-offs in simplicity. As with any infrared thermometer, follow the instructions carefully for each mode to get a reliable reading.

Where to Buy a Thermometer in Australia

Thermometers are widely available across Australia. Pharmacies such as Chemist Warehouse, Priceline Pharmacy, Amcal, and Terry White Chemmart stock the full range — from basic digital sticks to premium Braun ear and forehead models — and pharmacy staff can help you match a device to your family's needs. Major supermarkets including Woolworths and Coles carry basic digital and some infrared thermometers, and online retailers offer the widest selection. Prices vary between retailers and over time, so it is worth comparing before you buy. Whichever retailer you choose, look for established medical device brands with an Australian warranty.

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)

• radio_button_uncheckedWait at least 15 minutes after eating, drinking, or exercising.
• radio_button_uncheckedPlace the tip under the tongue, towards the back, and close your mouth.
• radio_button_uncheckedBreathe through your nose and keep still until the thermometer beeps.
• radio_button_uncheckedNormal oral temperature is around 36.8 degrees Celsius, but anywhere from 36.2 to 37.2 degrees is considered normal.

Ear (Tympanic)

• radio_button_uncheckedUse a clean probe cover for each reading.
• radio_button_uncheckedFor adults and children over 1 year: gently pull the ear up and back to straighten the ear canal.
• radio_button_uncheckedFor children under 1 year: gently pull the ear straight back.
• radio_button_uncheckedInsert the probe snugly into the ear canal and press the button.
• radio_button_uncheckedWait for the beep. Do not move the thermometer during measurement.
• radio_button_uncheckedAvoid using immediately after the person has been lying on that ear — wait 5 minutes.

Forehead / Non-Contact

• radio_button_uncheckedEnsure the forehead is dry — wipe away sweat before measuring.
• radio_button_uncheckedHold the thermometer at the distance specified in the instructions (usually 3 to 5cm).
• radio_button_uncheckedKeep the person out of direct sunlight or away from heaters before measuring.
• radio_button_uncheckedFor contact forehead thermometers, swipe smoothly across the forehead from the centre to the temple.
• radio_button_uncheckedIndoor temperature extremes can affect readings — let the person acclimatise for a few minutes if they have just come inside.

Underarm (Axillary)

• radio_button_uncheckedPlace the tip in the centre of the armpit, with the arm pressed firmly against the body.
• radio_button_uncheckedHold for the full measurement time (often 3 to 5 minutes for underarm).
• radio_button_uncheckedUnderarm readings tend to be 0.5 to 1.0 degrees lower than oral readings.
• radio_button_uncheckedThis method is the least accurate but can be useful for very young children or people who cannot use oral or ear methods.

What Temperature Is a Fever? 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

Children

Newborns and Babies Under 3 Months

Temperature measurement in very young babies needs extra care. For newborns and babies under 3 months, a digital underarm (axillary) reading is the preferred home method — ear thermometers are not suitable because the ear canal is too narrow, and underarm measurement is gentle and avoids the variability of forehead readings. Most importantly, the threshold for action is much lower in this age group, so any reading at or above 38.0°C should be treated as urgent.

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:

• radio_button_uncheckedAny fever in a baby under 3 months old — go to the emergency department immediately.
• radio_button_uncheckedFever above 38.0 degrees Celsius in a baby aged 3 to 6 months — see a doctor the same day.
• radio_button_uncheckedFever above 39.0 degrees Celsius in adults that does not respond to paracetamol or ibuprofen.
• radio_button_uncheckedFever lasting more than 3 days in adults or more than 24 hours in children under 2 years.
• radio_button_uncheckedFever accompanied by a stiff neck, severe headache, rash, difficulty breathing, persistent vomiting, or confusion.
• radio_button_uncheckedFever in anyone with a weakened immune system, chronic illness, or who is undergoing cancer treatment.
• radio_button_uncheckedFebrile 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

• radio_button_uncheckedMatch the type to the user: Ear and forehead thermometers are best for young children. Digital stick thermometers are fine for adults.
• radio_button_uncheckedAge 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.
• radio_button_uncheckedBacklit display: Essential if you are checking a child's temperature in a dark bedroom overnight.
• radio_button_uncheckedMemory function: Useful for tracking whether a fever is rising or falling over several hours.
• radio_button_uncheckedOngoing costs: Ear thermometers require disposable probe covers ($8 to $12 per 40). Digital and forehead thermometers generally have no ongoing costs beyond battery replacement.
• radio_button_uncheckedSpeed: If you are measuring a squirming toddler, a 1-second ear reading beats a 60-second oral reading every time.
• radio_button_uncheckedBrand 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

What is the most accurate thermometer for adults in Australia?

For adults, a digital oral (under-the-tongue) thermometer used correctly is generally regarded as the most accurate option for home use, closely followed by a well-positioned ear (tympanic) thermometer. Both are widely available in Australia. The key is good technique: wait at least 15 minutes after eating, drinking, or exercising before an oral reading, and use a clean probe cover for ear readings.

What is the most accurate thermometer 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.

Which thermometer has the highest accuracy?

Digital probe (oral) and ear (tympanic) thermometers offer the highest accuracy among consumer devices, with good models typically accurate to within about 0.1°C. Forehead and non-contact infrared thermometers are convenient and fast, but their readings are more sensitive to sweat, ambient temperature, and technique, so they tend to be slightly less precise for borderline measurements.

What thermometer do doctors and hospitals use?

Healthcare settings commonly use professional-grade digital probe (oral) thermometers and tympanic (ear) thermometers, often with single-use probe covers for hygiene. These are the same measurement methods available in consumer devices — the clinical versions are simply built for high-volume, repeated use. For accurate measurement at home, a quality oral or ear thermometer uses the same underlying technology.

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 newborn?

No — ear thermometers are not recommended for newborns or babies under 6 months because their ear canals are too narrow to get an accurate reading. For babies in this age group, a digital underarm (axillary) measurement is the preferred home method. For any fever in a baby under 3 months, seek immediate medical attention regardless of the method used.

What temperature is a fever in children?

In Australia, a temperature of 38.0°C or above is generally considered a fever in children. A reading between about 37.6°C and 38.0°C is mildly elevated and usually only needs monitoring and keeping your child comfortable. If your child has a high fever, seems unwell, or is under 3 months old, contact your GP or call Healthdirect on 1800 022 222.

What is the best forehead thermometer in Australia?

A good forehead (temporal) thermometer balances convenience with reasonable accuracy. Dual-mode options that allow either a no-contact scan or a light forehead touch — such as the Braun No Touch + Forehead — tend to perform well, and models with positioning guidance and a colour-coded fever display are easier to use correctly. Remember that forehead readings are more affected by sweat and ambient temperature than ear or oral methods, so confirm a borderline reading with an oral or ear thermometer.

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.
