Trans-Tasman bubble OK despite NZ cluster.

New Zealand's latest cluster of COVID-19 has grown to three but Australian officials have so far held off making any changes to border arrangements.

Last Thursday, health authorities announced a security guard at New Zealand's biggest quarantine facility, the Grand Millennium hotel in Auckland, had contracted the virus.

By Monday, two further cases - a security worker and a cleaner - were unearthed, with genome sequencing showing links to the original case and a recent returnee at the facility.

Prime Minister Jacinda Ardern has downplayed the risk of an outbreak, saying the new cases had already isolated.

Ms Ardern told 1News she and the Director General of Health Ashley Bloomfield were "not anxious".

"It's someone we already identified, so that's always heartening," she said.

"As they are a close contact ... they were already in isolation."

While a small number of community cases previously prompted Australia to pause quarantine-free travel from New Zealand, on this occasion it has not done so.

Last week, Ms Ardern announced New Zealand would reciprocate quarantine-free travel from Australia from April 19, effectively creating a trans-Tasman bubble.

The country that's nearly completed its vaccinations in 16 days.

When plotted on a graph, the curve of Bhutan's COVID-19 vaccination drive shoots upwards from the very first day, surging past Israel, the United States, Bahrain and other countries known for vaccinating people rapidly.

Those countries took months to reach where they are, painstakingly strengthening their vaccination campaigns in the face of rising coronavirus cases.

But the story of Bhutan's vaccination campaign is nearly finished - just 16 days after it began.

The tiny Himalayan kingdom wedged between India and China has vaccinated nearly 93 per cent of its adult population since March 27.

Overall, the country has vaccinated 62 per cent of its 800,000 people.

The rapid rollout of the vaccine puts the tiny nation just behind the Seychelles, which has given jabs to 66 per cent of its population of nearly 100,000 people.

Its small population helped Bhutan move fast, but its success has also been attributed to dedicated citizen volunteers, known as 'desuups', and established cold-chain storage facilities used during earlier vaccination drives.

Bhutan has recorded 910 infections and one COVID-19 death so far. It has a mandatory 21-day quarantine for all people arriving in the country.

Johnson & Johnson will not be part of Australia's vaccine rollout.

Johnson & Johnson's one-dose vaccine will not be part of Australia's vaccine rollout, after the federal government confirmed it would not purchased any doses from the company.

The Morrison government had been in talks with the global pharmaceutical giant, but the vaccine is based on similar technology to the AstraZeneca vaccine - the rollout of which has been stymied by the discovery of a link to rare but serious blood clots.

The Federal Government has ruled out buying the Johnson & Johnson COVID-19 vaccine, believing it is too similar to the AstraZeneca jab.

A spokesperson for Health Minister Greg Hunt said those similarities were the reason the federal government had decided against pursuing the option any further.

It is being widely used in America's current vaccine rollout.

Australia has deals in place with Pfizer, AstraZeneca and Novavax, but the Novavax vaccine is yet to be approved.

Hundreds of properties feared lost in WA cyclone damage.

Western Australia's premier is set to inspect the damage inflicted by Tropical Cyclone Seroja amid fears hundreds of properties could be lost.

No deaths or major injuries have been recorded as a result of the cyclone which tore across WA's mid-west coast on Sunday night.

Much of the carnage was concentrated in popular tourist spot Kalbarri, 580km north of Perth and home to about 1400 people.

Premier Mark McGowan will on Tuesday visit Kalbarri, where up to 70 per cent of properties are thought to have been damaged.

About 40 per cent of those properties are believed to have sustained major damage including total loss.

"This has been a pretty dramatic and devastating event for many families and many people in the community and it'll be ongoing now for some weeks, potentially months," Mr McGowan said.

"I just urge everyone to be patient and be understanding."

Seroja made landfall south of Kalbarri about 8pm on Sunday as a category three storm with wind gusts up to 170km/h.

It has since been downgraded to a tropical low and has moved offshore from WA's south coast.

William, Harry remember Philip's wit.

Princes William and Harry have paid tribute to their grandfather Prince Philip, remembering his wit, sense of duty and barbecue skills.

The brothers issued separate statements amid a family rift that led to Harry's decision to step away from royal duties last year and some have speculated that their grandfather's funeral may offer an opportunity for them to talk over their differences.

Philip, who had been married to Queen Elizabeth for more than seven decades, died last week at 99.

William, who is second in line to the throne, honoured Philip's lifetime of service to the Queen and the United Kingdom as he remembered his grandfather's "mischievous sense of humour".

"My grandfather was an extraordinary man and part of an extraordinary generation," said the 38-year-old William.

"Catherine and I will continue to do what he would have wanted and will support the Queen in the years ahead. I will miss my Grandpa but I know he would want us to get on with the job."

Harry, who stepped away from royal duties last year and now lives in the US, has arrived in the UK to attend Philip's funeral service, which will take place on Saturday at Windsor Castle, west of London.

Harry's statement described Philip as a man who was "authentically himself".

"He will be remembered as the longest reigning consort to the Monarch, a decorated serviceman, a Prince and a Duke," the 36-year-old Harry said.

"But to me, like many of you who have lost a loved one or grandparent over the pain of this past year, he was my grandpa: master of the barbecue, legend of banter and cheeky right 'til the end."

Bushfire risk for SA as temps rise.

Nine South Australian districts have severe bushfire warnings in place as a burst of warm and windy weather increases the fire risk.

The Bureau of Meteorology says the remnants of tropical cyclone Seroja will be captured by a cold front moving across the state from the west.

That could bring wind gusts of up to 90km/h for a brief period on Tuesday with raised dust also expected ahead of cooler weather from Wednesday.

COVID case detected on bulk carrier off WA.

A bulk ore carrier has been blocked from berthing in Western Australia after a crew member contracted COVID-19 and was hospitalised.

The man in his 50s became unwell last week while aboard the Aqua Genie vessel in Commonwealth waters off the coast of Karratha.

A boat was sent to retrieve the man, who is described as being "quite unwell", and he was taken to Karratha Health Campus overnight.

Premier Mark McGowan said the man was expected to be flown to Perth later on Monday then taken by ambulance to a dedicated isolation ward.

He said the ship's captain had communicated that none of the remaining 20 crew aboard the ship were unwell.

Minority shareholders have reportedly been kept in the dark about Seven West Media lending $1.87 million in company funds to executive Roberts-Smith, who is the Queensland manager of the company.
