Brisbane voted as 2032 Olympic, Paralympic host.

Brisbane is celebrating after being awarded the 2032 Olympic and Paralympic Games by the International Olympic Committee in a landslide vote in Tokyo on Wednesday.

With three of the 80 members of the IOC abstaining, 72 voted for Brisbane and just five against in a sweeping show of support.

IOC president Thomas Bach said the bid ticked all of the boxes, underlined by Australia's "passionate love for sport".

"I think it's first of all a passionate love for sport, which the Aussies really demonstrate," Bach said.

"You could feel this during the whole presentation and I could feel it already during my visit a couple of years ago in Queensland."

The city's bid had earlier earned praise from the IOC for its high percentage of existing venues encompassing south-east Queensland, support from all levels of government and experience in organising major events.

Despite the IOC claiming it wasn't a "done deal", the Tokyo organising committee released an embargoed statement before the vote congratulating Brisbane.

Brisbane was preferred ahead of Budapest, Korea, Doha and Germany's Ruhr Valley, who had all expressed an interest in hosting the Games. Bach said the IOC had previously discussed Brisbane's bid but there was no agreement.

"You cannot blame the IOC members for a press release from the organising committee, I don't know what they had in mind ... but it had nothing to do with our procedures," Bach said.

The Brisbane 2032 delegation, including AOC President John Coates and Queensland Premier Annastacia Palaszczuk, made a formal final presentation to the IOC meeting.

Prime Minister Scott Morrison said securing the Games was a triumph for the nation.

"It's a historic day not just for Brisbane and Queensland, but for the entire country," he said.

"It also marks an important leap forward for Australia as we look toward major events that lock in economic growth and social benefits that will echo for years to come."

PM wants review of AstraZeneca age advice.

Australia's expert immunisation panel has been urged to consider expanding the age recommendation for the AstraZeneca vaccine to people under 60.

Prime Minister Scott Morrison has revealed he is making constant appeals to the Australian Technical Advisory Group on Immunisation.

Pfizer is the preferred coronavirus vaccine for people under 60.

"When they made the decision to restrict or have a preference for those under the age ultimately of 60 to have the Pfizer vaccine, they said they made that decision on the balance of risk," Mr Morrison said.

"Well, it's for them to now constantly reconsider how that balance of risk applies and provide their advice accordingly."

Australia has ample supplies of AstraZeneca, which is produced in Melbourne, but there is not yet enough Pfizer imports arriving to vaccinate people under 40.

Labor's health spokesman Mark Butler agreed with the Australian Medical Association that the prime minister had put unfair pressure on ATAGI.

"This is the prime minister using the power of his office, as the head of the country, trying to shelve responsibility for the terrible failures of this vaccine rollout onto them," he told theABC.

Just 14.5 per cent of people over 16 have been fully vaccinated almost five months after the vaccine rollout began.

The prime minister refused to apologise for the program's problems but acknowledged delays were regrettable.

NSW to wait until early next week to learn lockdown fate.

Sydney still has days to wait to see if stricter rules will help quash its COVID-19 outbreak and release the city from lockdown.

"We need to wait until at least the weekend and early next week to see the impact of those harsher restrictions," NSW Premier Gladys Berejiklian said on Wednesday.

The state recorded 110 new local COVID-19 cases in the 24 hours to 8pm on Tuesday, up from 78 the previous day.

That figure would have been "thousands and thousands" had Greater Sydney not entered lockdown, now in its fourth week, Ms Berejiklian said.

The premier has said the virus must be quashed before restrictions can be lifted.

But the premier refused to be drawn on whether her government could go harder if case numbers don't start to turn around.

"In truth, we won't live as freely as we need to or we would like until vaccination rates increase," she said on Wednesday.

"That is one thing the NSW government can't control."

At least 60 of the new cases were circulating in the community for part or all of their infectious periods.

More than half - 56 - of the new cases were still under investigation and had not been linked to existing clusters when they were announced.

Vic lockdown avoids COVID 'world of hurt'.

Victoria would be facing a "world of hurt" in coming weeks if authorities had not immediately locked down the state, Chief Health Officer Brett Sutton says.

Twenty-two new local cases were reported in Victoria on Wednesday, the state's highest daily total of the current outbreak.

It took the total number of active cases in the outbreak to 107, all of which have been linked.

But Professor Sutton says he suspects the state would already be dealing with 200 to 300 cases if it had not entered lockdown a week ago, citing the highly infectious nature of the Delta variant.

"It is a variant that takes off from dozens to thousands of cases within just a matter of weeks," he told reporters on Wednesday.

"If we'd locked down today, instead of when we did, we would get thousands of cases in the next couple of weeks. We'd be in a world of hurt ... over coming weeks if we hadn't done what we've done."

Health Minister Martin Foley said 16 of the 22 new cases were isolating while infectious, and the remaining six posed a low risk to the community as they visited few exposure sites.

There are currently five people in hospital with COVID-19, including a man from Barwon Heads in intensive care.

SA COVID-19 cluster expected to grow.

South Australia's COVID-19 cluster is expected to grow after jumping from six to 12 cases as more exposure sites are also identified.

Five of the latest cases are linked to the Tenafeate Creek winery at Yattalunga, north of Adelaide, with the sixth, a child under five, linked to The Greek restaurant in the city where a number of infected people dined over the weekend.

One of the cases from the winery, a man in his 40s, also attended a school at Gawler on Monday raising concerns for other staff and students.

Chief Public Health Officer Nicola Spurrier says with multiple cases linked to both the winery and the restaurant, both are considered superspreader sites.

Wednesday's rise in cases came a day into SA's week-long statewide lockdown.

The number of potential exposure sites has climbed well above 50, mostly in Adelaide's north and northeastern suburbs.

Premier Steven Marshall says authorities will do everything they can to increase testing resources amid reports of long lines forcing some to wait for more than 10 hours.

SA's virus cluster is linked to an 81-year-old man who recently arrived in Australia from Argentina and quarantined in Sydney before travelling to Adelaide, where he tested positive.

Genomic testing has confirmed the man became infected while in Sydney, not while in Argentina.

Olympics off to a celebratory start for the Matildas, but over before it started for another Aussie athlete.

Australian showjumper Jamie Kermond says he's remorseful for taking cocaine and being suspended from the Tokyo Olympics.

Kermond has been booted from Australia's Olympic team after testing positive for a metabolite of cocaine on June 26.

The three-time Australian equestrian champion hopes one day to be forgiven.

"It is likely that the positive result was from a single recreational use of the drug at a social event and had no connection with my sport of equestrian," Kermond said in a statement.

"I am extremely upset and remorseful as to what has happened and I accept full responsibility."

The 36-year-old from Victoria was to have made his Olympic debut in Tokyo, among three showjumpers on a nine-strong Australian equestrian team.

Meantime, the Matildas have won their first round match against New Zealand opening up Australia's campaign for Gold in Tokyo.
