Quick Guide to GP Asthma Care in Australia

Why Your GP Is Your Best Ally Against Asthma?

Nearly 2.8 million Australians live with asthma, which is about 1 in 9 people. For children under 15, the rate is even more concerning, with hospitalisation rates three times higher than for adults. But here’s the good news: with proper GP-led care, most asthma is highly manageable.

Your General Practitioner (GP) is the cornerstone of asthma care in Australia. From diagnosis to creating a personalised action plan, your GP guides every step of your journey. This quick guide will walk you through everything you need to know about asthma care in Australia, including major 2025 guideline changes that could affect how you use your puffer.

What Is GP Asthma Care? 

GP asthma care refers to the comprehensive, ongoing management of asthma provided by a general practitioner. This includes:

• Diagnosis using spirometry and clinical assessment
• Prescribing appropriate medications based on current guidelines
• Creating a written asthma action plan tailored to your symptoms
• Regular reviews to adjust treatment as needed
• Managing triggers like allergies, exercise, or thunderstorm asthma
• Coordinating care with specialists when necessary

Since the introduction of Australia’s first Asthma Handbook in 1990, asthma deaths have halved, from about 1,000 annually to just under 500. That’s the power of evidence-based GP care.

Major 2025-2026 Guideline Changes: What Every Australian Needs to Know?

The End of “Blue Puffer Only” Treatment

This is big news. The latest Australian Asthma Handbook has introduced a “major change of practice”. The old approach of using short-acting beta2 agonists (SABA), commonly known as “blue puffers”, alone is no longer recommended for people aged 12 and over.

Why the change? Research shows that relying only on blue puffers treats symptoms but not the underlying airway inflammation. This leaves patients at greater risk of severe flare-ups requiring oral corticosteroids or hospitalisation.

Professor Nick Zwar, Chair of the National Asthma Council’s guidelines committee, explains:

“The common approach was starting patients with mild asthma on SABA as-needed; however, this did not treat the underlying inflammation. Starting patients on the new recommendation for low-dose budesonide-formoterol as needed offers a more evidence-based approach.” 

What Should You Use Instead?

For adults and adolescents with asthma, the handbook now recommends either:

The key takeaway: All people aged 12 or over with asthma now need inhaled corticosteroid (ICS) therapy, no more SABA-only treatment.

What does this mean for you?

If you currently use only a blue reliever puffer:

1. Don’t panic, but do make an appointment with your GP
2. Your doctor may switch you to a combination inhaler (ICS + fast-acting bronchodilator)
3. The new approach significantly lowers your risk of severe asthma attacks 

Federal Health Minister Mark Butler urges Australians to “have another conversation with your GP about the best position you can be in” regarding asthma management.

The Written Asthma Action Plan: Your GP’s Most Powerful Tool

One of the most effective asthma interventions available is a written asthma action plan. This is a personalised document you develop with your GP that tells you exactly what to do based on your symptoms.

What does an Action Plan include?

• Green zone (well-controlled): Your daily preventer medication
• Yellow zone (worsening symptoms): When to increase reliever medication
• Red zone (medical emergency): When to call an ambulance

Why Every Asthma Patient Needs One?

Research consistently shows that patients with written action plans:

• Have fewer hospitalisations
• Experience better symptom control
• Feel more confident managing their condition
• Know exactly when to seek help

Ask your GP for a written asthma action plan, and review it at least once a year.

Thunderstorm Asthma: A Unique Australian Risk

Australia, particularly Victoria and the ACT, experiences a unique phenomenon called thunderstorm asthma. This occurs when high winds during a thunderstorm sweep up pollen fragments that are small enough to penetrate deep into the lungs.

Who Is at Risk?

• People with known asthma and grass pollen allergy
• People with seasonal allergic rhinitis (hay fever) without known asthma

Research shows that people with pollen allergies who only use an over-the-counter blue puffer are at high risk of severe exacerbations during thunderstorms.

Your GP Can Help You Prepare

The updated handbook advises that at-risk patients should:

• Receive ICS-containing treatment (not just a blue reliever)
• Ensure their reliever is up-to-date with adequate doses throughout pollen season
• Avoid exposure to outdoor air on high-risk days (gusty winds before rain)

Talk to your GP before spring if you have hay fever or grass allergies, even if you’ve never been diagnosed with asthma.

Diagnosis: How Your GP Confirms Asthma

Getting the right diagnosis is the first step to effective care.

Spirometry: The Gold Standard

Spirometry measures how much air you can breathe out and how fast. It’s the preferred diagnostic test for asthma.

What to expect:

1. You’ll take a deep breath and blow hard into a tube connected to a machine
2. The test is repeated after using a bronchodilator (reliever medication)
3. If your lung function improves significantly, asthma is likely

When Your GP Might Refer You?

Sometimes, your GP may recommend seeing a respiratory specialist if:

• Your asthma is difficult to control despite maximum treatment
• You need multiple courses of oral steroids
• Newer biologic therapies might be appropriate for severe asthma

Professor Zwar notes that biologics “can be very effective for people with severe asthma” and help “avoid large doses of inhaled corticosteroid and particularly… recurrent courses of oral steroids”.

Children and Asthma: Special Considerations

Children under 15 are three times more likely to be hospitalised for asthma than older Australians. This makes GP-led asthma care especially critical for families.

Asthma Action Plans for School

For children with asthma, schools require an Asthma Action Plan completed by your GP. This document:

• Guides teachers and staff on managing your child’s asthma
• Includes emergency contact information
• Specifies medication instructions

Talking to Your GP About Your Child

When visiting your GP for your child’s asthma:

• Bring a list of symptoms (when they occur, what triggers them)
• Note any missed school days due to breathing difficulties
• Ask about age-appropriate inhaler devices (spacers for young children)

What to Expect During Your GP Asthma Appointment

Initial Diagnosis Visit

Your GP will:

1. Take a detailed history (symptoms, triggers, family history)
2. Perform a physical examination
3. Arrange spirometry testing
4. Discuss your personal risk factors
5. Prescribe initial treatment (likely an AIR or MART regimen)

Follow-Up Reviews

Asthma is not a “diagnose once and forget” condition. Your GP should review your asthma at least annually and more often if:

• Your symptoms are changing
• You’ve had a recent flare-up
• You’re using your reliever more than twice a week
• You’re waking at night with symptoms

What to Bring to Your Appointment

• Your current inhalers (all of them)
• Your written asthma action plan
• A symptom diary (if you’ve been keeping one)
• List of any side effects from medications

Medications: Understanding Your Inhalers

Pros and Cons of GP-Led Asthma Care

Pros

• Holistic approach – GPs manage co-existing conditions like allergies or eczema
• Accessibility – No referral needed; most Australians have a regular GP
• Action plans – GPs are uniquely qualified to create written asthma action plans
• Coordination – Your GP can refer you to specialists when needed

Cons

• Variable expertise – Not all GPs have a special interest in respiratory medicine
• Time constraints – Standard appointments may feel rushed for complex asthma reviews
• Access issues – Finding a GP who bulk bills can be challenging in some areas
• Follow-up gaps – Patients may not return for regular reviews without reminders

Frequently Asked Questions

What is the first-line treatment for asthma in Australia?

For adults and adolescents (12+), the first-line treatment is now low-dose budesonide-formoterol as needed (AIR therapy), replacing the old SABA-only approach.

How often should I see my GP for asthma?

At a minimum, once per year for a review. More frequently, if your symptoms are changing, you’ve had a flare-up, or you’re using your reliever more than twice weekly.

Do I still need a blue reliever puffer?

Blue relievers (SABA) still have a role in emergency symptom relief. However, they should not be used alone without an inhaled corticosteroid. Your GP may prescribe a combination inhaler instead.

What is a written asthma action plan, and why do I need one?

A written asthma action plan is a personalised document from your GP that tells you exactly what to do based on your symptoms. It’s one of the most effective asthma interventions available, and every asthma patient should have one.

How do I prepare for the thunderstorm asthma season?

Talk to your GP before spring if you have hay fever or grass allergies. You may need ICS-containing treatment even if you’ve never been diagnosed with asthma. On high-risk days, avoid outdoor air exposure before storms.

Can my GP prescribe asthma medication for my child?

Yes. GPs diagnose and manage asthma in children of all ages. For school-aged children, your GP will also complete the Asthma Action Plan required by schools.

Is asthma care covered by Medicare?

Yes. GP consultations for asthma are covered by Medicare. If your GP bulk bills, you pay nothing. For written asthma action plans and chronic disease management, additional Medicare items may apply.

Conclusion

Asthma care in Australia has entered a new era. The shift away from blue-puffer-only treatment represents a major evidence-based improvement that could prevent thousands of severe flare-ups each year
