The Queensland government has promised no person impacted by the devastating floods over the last week will be left behind.
Now, the city of Rockhampton is bracing itself for the Fitzroy River to peak on Wednesday.
The river is expected to reach nine metres, revised slightly down from earlier estimates of 9.4.
Fair warning has been given to residents to prepare their homes and businesses, and the city's airport has now closed as floodwaters make their way onto the main runway.
Queensland Fire and Emergency Service deputy commissioner Mark Roche says his people are working hard to spread the warning further.
"We are helping the people be prepared. We are knocking on doors. We're providing sandbags and other information. And it's a very important task we have in the next couple of days."
Touring flood-ravaged areas in northern New South Wales, Prime Minister Malcolm Turnbull has described the scene as gut wrenching.
He says "enormous support" is being offered to devastated communities.
In the city of Lismore, where the town centre was inundated, he said federal and state disaster relief is being made available to those who lost their homes and businesses who lost stock.
"Through New South Wales and Queensland, we've seen nature flinging her worst at Australians. And we have got more support for flood recovery now than we ever had in our nation's history."
As he toured Lismore, Mr Turnbull helped volunteers clean a devastated restaurant, even getting down on his hands and knees to scrub a wall.
While there, he spoke with the restaurant's owner, Steve Krieg, and asked him about his insurance premiums.
It is an important issue for many people living in flood zones, and they are calling for the Federal Government to step in to compel insurers to cover all aspects of flood damage.
Mr Krieg explained, while the business did have insurance, the possibility of getting flood insurance specifically was not real for for him.
Turnbull: "You said you've got flood insurance?"
Krieg: "We can't afford flood insurance here. Our insurance policy in total now is anywhere between $25,000 to $30,000 a year to cover ourselves for everything but a flood. If we take flood insurance on top of that, we're looking at another $10,000 to $15,000."
The latest flood crisis has also brought an increased focus on mental health as locals rebuild their lives, some for the second, third or fourth time.
New South Wales SES deputy commissioner Mark Morrow has spoken of the hardships many are facing.
"There's some people there that, psychologically, will be broken from this event. They've been through previous events in 2001, 2005 some residents, in fact, would have experienced that 1974 flood. So they're in there with their sleeves rolled up, they're doing the best they can, but it will take weeks, if not months in some cases, to restore businesses and restore residential properties."
New South Wales premier Gladys Berejiklian and Emergency Services Minister Troy Grant have visited flood-affected areas in their state, saying they are prepared to do whatever is needed.
Berejiklian: "The likes of this haven't been seen for 40 years, and we have a lot to learn from this experience."
Grant: "Government will wrap their arms around each of the communities affected, whether it be financial through to mental health, to rebuild these communities."
