But South Western Sydney doctors have urged the community to make their GP their first port of call when they're sick and save hospital emergency departments for emergencies during the busy winter flu season.

Bowral GP Jo Senior said sick patients' first port of call should be their GP.

"It's been a difficult time for everyone lately, but GPs want you to know that we're still here for you," she said.

"Even during the coronavirus pandemic, it's safe to visit your GP. If you can avoid the emergency department, save the emergency department for emergencies and call your GP first."

If patients are seriously sick or hurt they should go to the hospital emergency department for treatment.

Specialty emergency physician at Bankstown-Lidcombe Hospital Dr Rebecca Davis, said GPs played a key role in dealing with many medical conditions that did not need attention in a busy emergency department.

"Some of the symptoms which might bring patients to the emergency department included severe chest pain, trouble breathing, severe burns or unconsciousness or feeling seriously unwell," she said.

Emergency doctor at Bankstown-Lidcombe Hospital Dr Omar Albavati, reminded the community to practice good hand hygiene this winter and to cover their mouths with their elbows or use a disposable tissue when coughing or sneezing.
