Bronchitis in Australia: Symptoms, Treatment, and When to See a GP
Bronchitis is inflammation of the bronchi, the airway tubes that branch off the windpipe and carry air into the lungs. When those airways become irritated, they swell, produce more mucus than usual, and the body tries to clear that mucus by coughing. That cough, often productive and sometimes lingering for weeks, is the symptom most people recognise.
It's worth being clear up front: bronchitis is not a single illness. It's an umbrella term that covers two quite different conditions.
- Acute bronchitis is a short-term viral illness, almost always following a cold or flu. It clears on its own within a few weeks and is the kind most adults have had at some point.
- Chronic bronchitis is a long-term condition, usually part of chronic obstructive pulmonary disease (COPD), and is defined by a productive cough most days for at least three months in two consecutive years.
The distinction matters because the cause, the treatment, and the urgency are different. Acute bronchitis rarely needs antibiotics. Chronic bronchitis needs structured ongoing care, not a one-off prescription.
If your cough is uncomfortable or lasting longer than you expected, an Australian GP can help you work out which type you're dealing with and what to do about it. You can book a telehealth appointment at Abby Health, seven days a week.

Knowing which type you have changes everything that follows.
Acute bronchitis
- Almost always viral. Common culprits include rhinovirus, influenza, RSV, parainfluenza, and SARS-CoV-2 (Therapeutic Guidelines, 2025).
- Typically follows two to three days of cold symptoms, then settles into a cough that lasts one to three weeks. A small minority of people cough for six weeks or more.
- Often produces mucus that's clear, yellow, or green. Mucus colour is not a reliable sign of bacterial infection on its own.
- Resolves on its own. Antibiotics are not recommended for routine acute bronchitis in otherwise healthy adults (RACGP and NPS MedicineWise both publish this advice).
Chronic bronchitis
- A structural condition, not an infection.
- Defined clinically as a productive cough on most days for at least three months in two consecutive years.
- Usually caused by long-term irritation of the airways, most commonly from smoking. Occupational exposure to dust, fumes, or smoke also contributes.
- Sits inside the broader diagnosis of chronic obstructive pulmonary disease (COPD), which affects around one in seven Australians over 40 (Lung Foundation Australia, 2024).
- Needs ongoing management: smoking cessation, inhaled therapies, pulmonary rehabilitation, and regular GP review.
The single most useful question is the timeline. A cough for two weeks after a cold is almost certainly acute bronchitis. A productive cough that's been part of your life for years is something else, and worth investigating properly. We cover the difference in more depth in acute vs chronic bronchitis.
The presentation is usually recognisable, especially when it follows a cold.
Common symptoms of acute bronchitis
- A cough that started during or right after a cold. Often dry at first, then turning productive as the illness progresses.
- Mucus that's clear, white, yellow, or green. Mucus colour reflects the body's immune response, not necessarily a bacterial infection.
- Mild chest discomfort or soreness, particularly after coughing fits.
- Sometimes wheeze or a tight feeling in the chest.
- Fatigue, mild fever (typically under 38.5°C), and a runny nose if a cold preceded it.
Common symptoms of chronic bronchitis
- A productive cough on most days of the week, present for months or years rather than weeks.
- Shortness of breath, particularly with exertion. This often worsens gradually over time.
- Mucus production that's worse in the mornings.
- Recurrent chest infections, sometimes several times a year.
- Wheeze and a feeling of chest tightness.
What's usually not bronchitis
- A short, dry cough without any chest involvement and no preceding cold (more likely a post-viral cough or allergic cough).
- A cough purely on exertion in an otherwise well person (consider exercise-induced asthma).
- A cough with sharp, one-sided chest pain that gets worse when you breathe in deeply (this can point to pneumonia or other chest pathology, and warrants in-person assessment).
If you're not sure what's going on, the safest move is a quick GP review. The pattern, timing, and the presence or absence of red-flag features are usually enough for a doctor to work out the most likely cause.
Most acute bronchitis is uncomfortable but not dangerous. A small number of presentations are not safe to ride out at home, and a smaller number need emergency care rather than a GP appointment.
Call 000 or go to an emergency department if you have:
- Severe shortness of breath, or breathlessness at rest.
- Chest pain that's sharp, severe, or doesn't ease.
- Lips or fingertips turning blue or grey.
- Coughing up blood, more than a small streak.
- Confusion, fainting, or severe weakness.
- A high fever (above 39°C) that won't come down with paracetamol or ibuprofen, especially with shaking chills.
See a GP within 24 to 48 hours if:
- Your cough is getting worse rather than better after a week.
- You have a fever that's persisted beyond three to four days.
- You're breathless on minimal exertion, even if not severe.
- You have an underlying lung condition (asthma, COPD, bronchiectasis) and your usual symptoms have changed.
- You're pregnant, over 65, immunocompromised, or have a chronic condition like diabetes, heart failure, or kidney disease.
- Your cough has lasted more than three weeks without improvement.

Treatment depends on the type.
For acute bronchitis
The strong national consensus, from Therapeutic Guidelines and NPS MedicineWise alike, is that antibiotics are not routinely recommended for acute bronchitis in otherwise healthy adults. Most cases are viral, antibiotics don't shorten the illness in that setting, and unnecessary use drives antibiotic resistance.
What actually helps:
- Rest and hydration. Both support the body's clearance of the infection.
- Paracetamol or ibuprofen for discomfort and fever.
- Simple steam inhalation or warm fluids to loosen mucus.
- Honey, in adults and children over 12 months, can ease cough as well as many over-the-counter cough syrups.
- If wheeze is present, a short course of a bronchodilator inhaler may help, prescribed by a GP.
Antibiotics may be considered in specific situations, including in patients who are frail, immunocompromised, or who have an underlying lung condition. A GP makes that judgement on a case-by-case basis.
For chronic bronchitis
Chronic bronchitis sits inside the broader picture of COPD and needs an ongoing care plan, not a one-off prescription. Standard elements include:
- Smoking cessation support. This is the single most effective intervention.
- Inhaled therapies (bronchodilators and, in some cases, inhaled corticosteroids) prescribed and reviewed by a GP.
- Pulmonary rehabilitation, a structured program that improves exercise tolerance and quality of life.
- Annual flu vaccination and recommended pneumococcal vaccination.
- A written action plan for managing flare-ups before they escalate.
You can pick up repeat prescriptions online for ongoing inhalers through Abby Health, with the same GP reviewing your care over time.
Online appointments for chest infections
Abby Health is an Australian online-first clinic with more than 300 GPs available seven days a week. For bronchitis, the practical workflow most people need is straightforward:
- A same-day or first-available appointment with a GP who reviews your history, asks the questions that separate acute from chronic, and listens to the timeline.
- A clear plan, including whether antibiotics are likely to help in your case, whether an inhaler would be useful, and what to watch for that would mean a face-to-face review.
- A medical certificate if you need time off work or study while you recover. Abby Health can issue these online during the same consultation. See online medical certificates for details.
- Online prescriptions sent direct to your nominated pharmacy, including repeat scripts for ongoing inhalers.
- Continuity. If your cough doesn't settle, the same care network holds your history, so you don't have to start from scratch at a follow-up appointment.
What telehealth can't do is replace an in-person physical examination if one is clinically required. If a GP needs to listen to your chest, examine for signs of pneumonia, arrange a chest X-ray on the same day, or run pulse oximetry on the spot, you'll be referred to in-person care. Abby's GPs make that call openly when it matters.

How long does acute bronchitis usually last?
Most people clear within one to three weeks. A small proportion cough for six weeks or longer after the underlying infection has resolved. A cough beyond three weeks is worth a GP review.
Do I need antibiotics for bronchitis?
Usually not. The national clinical guidance is that antibiotics aren't routinely recommended for acute bronchitis in otherwise healthy adults, because most cases are viral. A GP can identify the specific situations where antibiotics do help (for example, in patients who are frail, immunocompromised, or have an underlying lung condition).
How is bronchitis different from a chest cold?
They overlap considerably. A chest cold is loosely the early phase of acute bronchitis. If symptoms are mild and brief, most people call it a chest cold; if the cough is prominent and persistent, most clinicians call it acute bronchitis.
Can I get bronchitis treated online?
Yes, in most cases. A telehealth GP can take a history, assess severity, recommend treatment, prescribe medications where appropriate, and issue a medical certificate. The exception is when a physical examination, chest X-ray, or in-person observation is clinically needed. In those situations Abby's GPs will refer you to in-person care.
Is chronic bronchitis the same as COPD?
Chronic bronchitis is one of two main forms of COPD, alongside emphysema. Many people have features of both. Diagnosis is confirmed with spirometry, a breathing test usually done in person.
What can I do at home to feel better faster?
Rest, hydrate, take paracetamol or ibuprofen for discomfort or fever, and consider honey for cough in anyone over 12 months. Avoid smoking and second-hand smoke. If you're wheezy, a GP can advise whether a bronchodilator inhaler is appropriate.
When should I worry about a cough?
Seek urgent care for severe breathlessness, chest pain, blue lips or fingertips, coughing up significant blood, confusion, or a high fever that won't come down. See a GP if your cough is getting worse after a week, lasts more than three weeks, or you have an underlying lung condition.
