Queensland is closing most national parks, walking tracks and 4WD areas, as the state's death toll from COVID-19 rises to three and a full border lockdown takes effect from midnight.
The state's latest victim is an 85-year-old Darling Downs man who died overnight in hospital in Toowoomba, west of Brisbane. His death takes the national toll to 24.
A total of four Queenslanders have now died, including one who died in Sydney after being infected while on board a Royal Caribbean cruise ship that docked there.
Queensland authorities confirmed on Thursday that another 57 people have been infected with the virus, taking the state's total cases to 835.
Premier Annastacia Palaszczuk is ramping up Queensland's coronavirus crackdown as people continue to ignore the ban on non-essential travel.
The national parks will be closed to the public, along with hiking tracks, picnic areas, camping areas, swimming holes and lookouts, from Friday.
Hundreds of people are still trying to get into Queensland despite the state shutting down its border with NSW.
From Friday, anyone who does not have a state government permit proving they have a legitimate reason for cross-border travel will be denied entry.
Freight trucks are exempt, as are travel for work and medical reasons.
"We're going to a hard border closure so people can expect to see a change to some of the streets that they would normally go through," State Disaster Co-ordinator Deputy Commissioner Steve Gollschewski said.
Ms Palaszczuk said all Australians must prepare for a long period of living under severe restrictions, including not leaving home unless it's really necessary.
"The minimum I'm hearing is six months. If we flatten that curve, we are not going to reach the peaks until well into the middle of this year," she said.
The premier is also threatening to shut down Queensland's beaches, with people continuing to ignore social distancing.
"If people aren't complying with social distancing, we are going to have to crack down So, final warning, everyone."
A charter plane carrying 222 Australians and 28 New Zealanders who were stranded in Nepal landed in Brisbane on Thursday.
The group will be forced into 14 days of quarantine under strict measures to stop the importation of new cases of the coronavirus.
Nepal is now in lockdown and governments around the world have been working to get their citizens out amid fears the small country's health system will not cope.
Meanwhile, Queenslanders have been urged to join a "care army" to help older people get through the crisis.
Under the scheme, government officials are matching older people confined to home with volunteers who'll help them with tasks such as shopping for food and pharmacy supplies.
"If we can keep our seniors safe, we can prevent them from ending up in hospital or in ICU, and potentially save lives," Ms Palaszczuk said.
