Coronavirus is having an enormous impact on the economy.

In a bid to soften the blow, Prime Minister Scott Morrison has announced more money will be given to welfare recipients.

The Government is also helping more people access welfare payments by waiving some asset tests and waiting periods.

"We will be supercharging our safety net," Mr Morrison said on Sunday.

"This is focusing on those who are going to feel the first blows."

There were a couple of announcements in yesterday's press conference, but the payment Australians seem most interested in, according to Google search results, is one called the Coronavirus Supplement.

What is the Coronavirus Supplement?

It's an additional top-up payment for people on welfare.

How much is the Coronavirus Supplement?

It is worth $550 a fortnight ($275 a week). It means the JobSeeker Payment, which used to be known as Newstart, will effectively double.

Who is eligible for the Coronavirus Supplement?

It goes to anyone receiving:

JobSeeker Payment (formerly known as the Newstart Allowance)

JobSeeker Payment (formerly known as the Newstart Allowance) Sickness Allowance

Sickness Allowance Youth Allowance for jobseekers

Youth Allowance for jobseekers Parenting Payment Partnered

Parenting Payment Partnered Parenting Payment Single

Parenting Payment Single Partner Allowance

Partner Allowance Farm Household Allowance

When does it start?

Payments will begin on April 27 and will be available for at least six months.

Are small business owners and casual workers eligible?

Yes — if they suddenly find themselves earning less than $1,075 a fortnight.

Treasurer Josh Frydenberg said the Government would ensure people who had their business closed, saw customers disappear, or had casual shifts cut could access the Coronavirus Supplement.

"We have waived the assets tests and waived the waiting period but there is still the income test so if you earn $1,075 a fortnight you will get that full $550 Coronavirus Supplement," Mr Frydenberg said.

"This is good news for a sole trader who is still in work but has seen the income reduce.

"If you are a casual and you still have some hours but your income has fallen below that $1,075 a fortnight you will get the supplement."

How to claim the Coronavirus Supplement

If you're already receiving one of the welfare payments listed above, you don't actually have to do anything.

Services Australia will automatically pay the Coronavirus Supplement to eligible recipients each fortnight.

If you're not currently receiving welfare, you'll need to apply.

Remember, the Government has temporarily expanded eligibility for the JobSeeker and Youth Allowance payments, meaning you may be eligible if you're:

A permanent employee who has been stood down or lost your job

A permanent employee who has been stood down or lost your job A sole trader, self-employed, a casual or contract worker whose income has reduced

A sole trader, self-employed, a casual or contract worker whose income has reduced Caring for someone who's affected by coronavirus

Income testing will still apply but if you're earning less than $1,075 a fortnight, Centrelink should approve your claim, meaning you would get the supplement.

However, if your partner earns more than $79,762 a year you will not be eligible for JobSeeker payments (the partner income threshold was increased from $48,100 on March 30).

How do I apply for JobSeeker or Youth Allowance?

You can apply online at MyGov using a Centrelink account, or contact Services Australia by phone for more details.

But you may have to wait.

The MyGov website crashed on Monday morning after thousands of people tried to access Centrelink payments.

Government Services Minister Stuart Robert originally claimed a distributed denial of service (DDoS) cyber hack had occurred, but hours later told Parliament there was no evidence of an attack.

There were also long queues on both the phone hotline and in person at service centres.

Centrelink issued a statement warning people "it will take a little longer than usual" to get help, but said many questions were answered on its website and social media accounts.

"Please consider the health and safety of our customers and staff and do not visit our service centres unless there's a critical need for you to be there," the statement said.

The Government plans to hire an additional 5,000 staff for Services Australia — the agency responsible for Centrelink payments — to help deliver the new measures.

Is there a waiting period for the Coronavirus Supplement?

The Coronavirus Supplement will not come into effect until April 27.

Can I still access annual leave or income protection?

No. You can't access employer entitlements, such as annual leave or sick leave, at the same time as getting JobSeeker or Youth Allowance payments.

You also can't receive the payments if you're accessing income protection insurance.

Will there be more payments in future?

At his press conference on Sunday, the Prime Minister said the economic stimulus measures implemented so far were "unprecedented".

In total, they are worth $189 billion and account for around 9.7 per cent of the nation's GDP.

But he foreshadowed more announcements of this kind.

"This will not be the Treasurer and my last visit to these podiums to make announcements on these measures," Mr Morrison said.

"This is focusing on those who are going to feel the first blows. There will be more packages and more support."
