Queensland has recorded 10 new COVID-19 deaths, with 884 people in hospital being treated for COVID symptoms.
Hospitalisations include 52 people in an intensive care unit and 18 on ventilators.
Of the deaths, one person was in their 40s, one in their 50s, six in their 80s, and two in their 90s.
One person was unvaccinated, six were double vaccinated, and three had received a booster.
Queensland Chief Officer John Gerrard said the state had recorded another 15,050 cases.
Dr Gerrard said it was clear the COVID-19 wave had peaked in New South Wales, which he called "perhaps the most positive news in the past 24 hours".
Dr Gerrard added Queensland's peak would not be uniform across the state and would likely start in the Gold Coast, then Brisbane and regional centres.
Dr Gerrard said he could also not rule out a second peak.
"We will always plan for the worst and hope for the best, so it is conceivable that there might be another wave in the wintertime as the weather becomes cooler," he said.
"There may or may not — but we don't know that — we are certainly planning for that in Queensland Health, even though it may not happen."
Queensland cases 'almost certainly greater than a million'
There have been 250,000 COVID cases in Queensland since domestic borders reopened, but Dr Gerrard said the real figure could be four times that number.
Dr Gerrard reminded people that COVID would still be very active in the community after the peak in cases.
"What will then happen over the ensuing weeks is that the number of cases are likely to fall at about the same rate as it has risen," he said.
"Although, a slight caveat on that is that with the opening of schools — there's likely to be some more transmission associated with it with the return to school."
School delay a 'very sound' decision
Queensland's school term has been delayed by two weeks in order to avoid clashing with the peak in COVID cases.
Dr Gerrard said the confirmation of when the peak would hit had solidified the decision to push back the commencement of classes.
"It affirms the decision to delay the opening of schools until after the predicted peak, which was exactly when the schools were going to open," he said.
"Schools were going to open next week, which is when we expect Gold Coast to peak and then Brisbane shortly thereafter, so I am very confident that the decision to delay the schools opening by two weeks was a very sound public health measure."
International flights arrive in Queensland
From Saturday, fully vaccinated travellers can enter Queensland without having to quarantine.
They instead need to take a rapid antigen test within 24 hours of arrival.
The first international flight into Brisbane landed after 9:00am on Saturday.
Queensland Tourism Minister Stirling Hinchliffe said easing quarantine requirements for international travel would help to strengthen the state's economy.
"We'll see over the next week, flights into all of our international airports throughout Queensland, receiving passengers and seeing them reuniting with family or getting back to their studies or getting to work," Mr Hinchliffe said.
"Hopefully soon, we'll see a lot more tourists, making sure that we can see this as the real light at the end of the tunnel for the Queensland $6 billion tourism industry.
"But most importantly, I'm very focused today on welcoming those — particularly on that first Singapore Airlines Flight — welcoming those people who come in and might be students, some of the 30,000 people enrolled in Queensland universities institutions who can return to face-to-face studies."
