Blood Pressure Guidelines in Australia

The national reference is the National Heart Foundation of Australia's Guideline for the diagnosis and management of hypertension in adults, published in 2016 and still current today. It classifies clinic readings into six grades:

When the two numbers fall into different categories, the higher category applies. The guideline also names a separate pattern, isolated systolic hypertension — a systolic above 140 with a diastolic still below 90 — which is common in older adults. Australia's consumer health service, healthdirect, states the same bottom line in one sentence: blood pressure is considered high if readings are consistently more than 140/90 mmHg.

The scale of the problem is why the categories matter: in the data behind the national guideline, about 1 in 3 Australian adults — 6 million people — were hypertensive, and more than two-thirds of them had uncontrolled or untreated blood pressure.

One thing to watch: a new joint Australian guideline is on its way. The Heart Foundation, the Stroke Foundation and Hypertension Australia are finalizing the 2026 Australian Guideline for the Diagnosis and Management of Hypertension in Adults, expected in late 2026 — so expect updated advice, and possibly updated numbers, when it lands.

Australia treats home monitoring as a first-class diagnostic tool, not a hobby. The 2016 guideline says that if a clinic reading is at or above 140/90 mmHg, or hypertension is suspected, ambulatory and/or home monitoring should be offered to confirm it — and it sets a lower bar for home readings: hypertension is diagnosed from a home average of 135/85 mmHg, because relaxed home readings run lower than clinic ones.

The Australian expert consensus protocol for that home average is specific:

• Two readings in the morning and two in the evening, every day for 7 days.
• Discard the first day — it reflects you getting used to the routine — and average the rest.

Two equipment rules come with it. The guideline recommends against finger and wrist devices — use a validated upper-arm cuff (more on validation below). And it expects proper technique: our step-by-step measurement guide covers the setup, and a structured blood pressure log turns the week into something your GP can act on. The Heart Foundation also publishes a printable 7-day measuring guide and diary among its downloadable resources if you prefer paper.

The single most important spec on an Australian shopping list is validation — independent testing showing the monitor's readings are accurate. It is not a given: an Australian study of nearly 1,000 blood pressure monitor models sold online in Australia found only about 6% were validated, and none of the wristband-style devices were.

Australian researchers direct buyers to STRIDE BP, an international registry of validated monitors co-sponsored by the European and International Societies of Hypertension — check a model there before you pay for it. Hypertension Australia likewise maintains consumer guidance on finding an accurate monitor, for the same reason: most of what's on the market has never been formally tested.

Combine that with the guideline's device rule — upper-arm cuff, not finger or wrist — and the buying decision gets simple: a validated upper-arm monitor, sized to your arm. Our guide to monitor types compares the options in detail.

Australia is unusual in having a dedicated Medicare item for prevention. A Heart Health Check is a GP appointment of at least 20 minutes covering your blood pressure, cholesterol and other risk factors, your estimated risk of a heart attack or stroke in the next five years, and a plan to lower it. The MBS item is claimable once every 12 months from age 30, and the check is free at practices that bulk bill it — ask about the cost when you book.

The Heart Foundation's recommendation on who should book one: everyone from 45, from 35 if you live with diabetes, and from 30 for Aboriginal and Torres Strait Islander peoples, provided you don't already have heart disease.

Outside the GP's office, the Stroke Foundation runs "Australia's Biggest Blood Pressure Check" every May, encouraging Australians to get their blood pressure checked at a doctor or pharmacy — timed around World Hypertension Day. If it has been more than a year since a professional measured your blood pressure, either route gets you a current number to anchor your home readings against.

Australia diagnoses hypertension from 140/90 mmHg. The US moved its own boundary in 2017: the ACC/AHA guideline defines hypertension from 130/80 mmHg, and Australia has not adopted that change — a reading of 134/84 is "stage 1 hypertension" to an American cardiologist and "high-normal" to an Australian GP. Neither is a mistake; they are different judgement calls about where treatment and diagnosis should begin, and Australian practice follows the Australian numbers.

That matters when you use an app. Blood Pressure Journal ships with the US ACC/AHA bands as its defaults — below 120/80 normal, 130/80 and above hypertension — so out of the box it will flag some readings an Australian doctor would call high-normal. Its classification ranges are customizable, so if your GP works to the Heart Foundation's thresholds you can set the app to match: hypertension from 140/90, matching the table above.

Whichever bands you display, the number that matters for an Australian diagnosis is your home average against 135/85 — if a week of properly taken readings averages at or above that, it's a conversation to have with your GP.

The Australian guideline treats severe elevations — readings above 180/110 mmHg — as urgent. A single high number on its own is not a reason to panic: sit quietly for a few minutes and measure again, because stress, rushing, or a badly placed cuff can produce one alarming reading.

It becomes an emergency when a very high reading comes with symptoms. healthdirect's list: chest pain, shortness of breath, severe headaches, vomiting, vision problems, confusion, or seizures. With any of these, call triple zero (000) or go to your nearest emergency department.

If you're unsure what to do about a high reading without emergency symptoms, the healthdirect helpline on 1800 022 222 (known as NURSE-ON-CALL in Victoria) puts you through to a registered nurse 24 hours a day, 7 days a week.
