But it did increase levels of psychological distress, particularly for younger people.

The JobKeeper program, increased JobSeeker supplement and labour market recovery were protective factors against suicide, the Australian Institute of Health and Welfare found.

An examination of coronial data across Victoria, NSW and Queensland did not show an increase in deaths by suicide during the pandemic.

"In the early days of the COVID-19 pandemic, it was widely speculated that there would be large rises in the number of deaths by suicide," the institute's deputy chief executive Matthew James told reporters.

"Luckily, these predictions have not come to pass."

Suicide deaths for most OECD countries had not risen during the pandemic, Mr James said.

About 3000 Australians die by suicide each year, an average of nine a day.

In 2019 there were 3318 such deaths, a rate of 12.9 per 100,000 people.

The institute said data from Victoria, NSW and Queensland coroners did not show an increase in suspected suicide deaths in 2020, or since the COVID-19 pandemic began.

In Victoria, 714 people died by suicide last year compared with 720 in 2019.

In NSW, 900 people died by suicide in 2020 compared with 943 the previous year.

However, there was a spike in the use of mental health services including crisis lines from the start of the pandemic.

Slightly more than 10 per cent of Australians used Medicare-subsidised mental health services in 2019-20, up from six per cent a decade prior.

Australian National University modelling showed a significant rise in the proportion of Australians experiencing severe or very severe psychological distress since 2017.

It's still higher, compared with pre-pandemic levels, for people aged up to 44, which is thought to be associated with job loss.

But psychological distress levels for Australians aged 45 and older had returned to pre-pandemic levels and in some cases was even lower.

Ambulance data showed the rate of attempted suicide fell slightly in Victoria last year after rising in 2019.

In NSW, the rate of attempts increased in 2020 but it was a smaller increase compared with the previous year.

"In other words, it's hard to see a very obvious COVID effect from that," Mr James said.

Women and girls take their own lives more often than men, particularly those between the ages of 15 and 19.

But men comprise three-quarters of suicide deaths, most frequently in their 40s and also from the age of 85.
