This year's flu vaccination will be available in most towns in the coming weeks, and for the first time NSW pharmacies will be providing the flu shot for individuals above the age of 10.

"Although the flu vaccine won't protect people from the COVID-19 virus, it will help reduce the chance of contracting the seasonal flu which may weaken a person's immune system, and reduce the pressure on health resources" said Wagga GP Jodi Culbert.

"Vaccination is the best way to prevent the flu and we encourage people to get vaccinated - even if they're fit and healthy. The more people that get vaccinated the more protection there is for everyone."

Children aged six months to five years, people aged 65 and over, pregnant women, Aboriginal people and those with high-risk medical conditions are eligible to be vaccinated for free by GPs.

Residents are encouraged to contact their local GP to make an appointment first, to ensure effective delivery of the vaccine.

Dr Culbert said there were other hygiene practices that would also contribute to limiting the spread of the flu.

"People need to wash their hands correctly, cover their mouths and noses with a tissue when coughing and sneezing, dispose of their tissues into a bin, and stay at home if they are unwell," she said.

"Older people and those who are very young, pregnant or experience chronic health are especially vulnerable during the winter months and at higher risk of developing complications from the flu, which is why following good hygiene practices is so important."

Murrumbidgee Local Health District (MLHD) Chief Executive Jill Ludford said there is a significant increase in the number of people presenting to hospital emergency departments during the flu season.

"With the additional demand expected on our health services we've looked to optimise our patient flow between hospitals, improving coordination between ambulances, hospitals and primary care," Ms Ludford said.
