NSW small- and medium-sized businesses have been given the green light to restock for Christmas after the state government released an economic recovery plan it hopes will lead "major summer trade".

It comes as the state records 360 new local COVID-19 cases in the 24 hours to 8pm on Monday, as well as five deaths.

A day after the state began to emerge from a near four-month lockdown, Premier Dominic Perrottet and Treasurer Matt Kean on Tuesday announced a package to support business.

Shops, gyms, cafes and hair salons were on Monday overrun as fully-vaccinated patrons responded to weeks of pent-up demand, and as people ventured more than five kilometres from home.

While authorities and business owners were nervous about potential conflict because unvaccinated people are currently denied entry and in-venue service, most in NSW were on their best behaviour.

Mr Perrottet said Tuesday's announcement was "all about confidence".

"Last year, as we came through the pandemic, business confidence was key - was crucial - to driving economic growth, to ensuring that businesses continued to employ and bring people on," he said.

Eligible businesses with an annual turnover between $75,000 and $50 million will be able to apply for a grant of up to $20,000 to compensate for loss of perishable stock, or claim $10,000 for reduced capacity to sell non-perishable items, if they are impacted by a lockdown.

"As we head into the summer months and Christmas trade ... businesses can go out and invest in their businesses," the premier said.

He insisted any future lockdown would be a last, not first, resort.

The package also includes toll road relief for businesses with an annual wages cost below $1.2 million which don't qualify for payroll tax.

Those businesses will be able to claim road tolls under the small business fees and charges rebate, increased to $2000.

"We know that is really going to support tradies," he said.

With NSW already on the verge of another critical COVID-19 vaccination milestone, crowds could also soon be back in stadiums and nightclubs.

More than 80 per cent of the population is predicted to be fully vaccinated as soon as next Monday, triggering freedoms on October 25.

As of Sunday, vaccination coverage sits at 74 per cent.

Unlike his predecessor, Mr Perrottet said he had no concerns labelling Monday a "Freedom Day" for the state but reiterated caution.

Despite current limitations - including mask-wearing, social distancing, strict density limits and venue caps - Small Business Minister Damien Tudehope described the mood in NSW as one of elation.

Later on Tuesday, NSW parliament will resume after a three-month hiatus, with Mr Perrottet facing his first Question Time as premier after the resignation of Gladys Berejiklian earlier this month.

Australia will get a new domestic airline from early next year when Bonza expects to take to the skies, taking advantage of an expected boom in air travel in a post-pandemic world.

Bonza, which is backed by a US investment firm and headed by ex-Virgin Blue executive Tim Jordan, is promising "ultra low prices" to travel around the country in 2022.

"Bonza's mission is to encourage more travel by providing more choices and ultra-low fares, particularly into leisure destinations where travel is now often limited to connections via major cities," CEO and founder Mr Jordan said.

Bonza's ambition is broad but it appears there will be a focus on regional communities, with new routes in the wings.

Mr Jordan has more than 25 years of experience in the aviation industry and recently was managing director of FlyArystan, the first low-cost carrier in Central Asia.

US investment firm 777 Partners is backing Bonza, which subject to regulatory approval expects to launch services in early 2022 with Boeing 737-8 aircraft.

"We see huge potential in the Australian market to deliver the benefits and options that an independent low fare airline brings," 777 Partners managing partner Josh Wander said in a statement.

Bonza will sport white and purple livery on its aircraft and plans to base its headquarters in regional Australia, with the exact location yet to be revealed.

A father and son who travelled from Sydney's east to Byron Bay, sparking a lockdown in the region, have pleaded guilty to most of the charges they face.

Neither Zoran Radovanovic, 52, who was treated for COVID-19 in Lismore Base Hospital after testing positive to the virus, nor his 19-year-old son Kristian appeared in Lismore Local Court on Monday when their cases were mentioned.

Police alleged the pair violated public health orders after going to Byron Bay in late July. The region was plunged into a one-week lockdown in August after the father's positive test.

Zoran Radovanovic's lawyer on Monday emailed guilty pleas to four charges of failing to comply with electronic registration (QR codes).

He is also facing three charges of not complying with COVID directions.

His son entered guilty pleas to all four charges against him: two of not complying with electronic registration, one of not complying with directions and one of not wearing a face mask in public transport or a taxi.

Both remain on bail, with the father's case to be mentioned again at Lismore on November 15 and the son's matter to be mentioned in Waverley Local Court on November 8.

Scott Morrison has championed the power of coronavirus vaccines to restore Australians' freedoms as he exited quarantine and NSW ended a 100-day lockdown.

The prime minister has been isolating at The Lodge in Canberra after returning from a trip to the United States.

Mr Morrison, who will return home to Sydney, urged fully vaccinated residents in his state to enjoy their restored freedoms with a bevvy of restrictions lifting in NSW.

He also sent a message to people in states that have avoided major lockdowns and rampant outbreaks, like Western Australia and Queensland.

"We need those vaccines to ensure that when COVID inevitably comes, that in those states you will be able to continue on as you have," the prime minister said on Monday.

"So let's keep going, Australia, with the vaccination program."

WA and Queensland trail the nation on double-dose vaccination rates, while the ACT and NSW have a commanding lead ahead of Tasmania and Victoria.

Almost 62 per cent of people aged 16 and above across Australia are fully vaccinated against coronavirus.

There were 496 new local cases and eight deaths reported in NSW on Monday, while Victoria registered 1612 infections and eight fatalities.

Treasurer Josh Frydenberg said the focus should shift from daily case rises to hospitalisations as immunisation rates rose.

"The Delta genie is out of the bottle so we've got to learn to live with the virus," he told 2GB radio.

Mr Frydenberg said the effectiveness of lockdowns was being diminished each day the highly contagious variant circulated.

Health Minister Greg Hunt believes health systems in NSW and Victoria are prepared to cope with any rise in cases as restrictions lift.

"What we're doing in Australia is giving ourselves the best chance to get on with our lives. Our hospital systems are well prepared," he told ABC radio.

Mr Hunt said the government was planning for booster shots to be available to everyone if the expert immunisation panel gave the green light at the end of the month.

Up to 500,000 people with severely compromised immune systems gained access to third jabs from Monday to boost their protection.

The health minister said international evidence was showing vaccines were offering strong ongoing protection against hospitalisation, serious illness and death.

NSW lifted restrictions after passing 70 per cent double-dose coverage, a mark locked-down Victoria is expected to reach before the end of the month.

The ACT's lockdown ends on Friday.
