Sugar cane farms in the Bundaberg area and beyond have now been underwater for several days, causing serious damage to crops.
For many, it's an anxious watch and wait game as flood waters recede and reveal what's left of the cane fields.
Fruit and vegetable growers are also in distress.
Orchards have been swamped, and fruit trees uprooted by wind and fast flowing floodwaters.

EMILY BOURKE: It seems Queensland's farmers can't take a trick.
After the floods of 2011, many primary producers were just getting back on their feet.
And now they're underwater again.
JEFF ATKINSON: I've been here for 25 years and this is the biggest one I've seen.
EMILY BOURKE: Jeff Atkinson is a sugar cane grower in Maryborough. His cane crop has been underwater for three days and time is marching on.
JEFF ATKINSON: Three days that - I've had cane you can't see a leaf.
And four days I think is just too long, and that's the concern.
I've done a rough estimate, and probably about a $40,000 loss on my own individual farm.
It's going to be too late to replant now, and I have been talking to other growers, and some of them are even concerned they don't have cane that's going to be suitable to plant, so that's another issue.
EMILY BOURKE: And he warns it's not just a disaster for individual growers.
JEFF ATKNISON: There's a sugar mill in Maryborough and it needs every tonne it can get, and unfortunately, this is not going to help the situation.
Then the mills got farms, and then there's the transport side of it to cart the cane.
You've got harvesting contractors; it could involve two or three hundred people.
Just that, without that flow on to the town and the businesses.
EMILY BOURKE: Tony Castro grows 130 hectares of cane in northern Bundaberg. His property is still cut off and he's yet to inspect the damage.
TONY CASTRO: There could be some blocks of cane that have had parts of the block gouged out by flowing water, and because we had a late finish to the harvesting season last year, some of our late-harvested crops are not advanced in size, and if the waters don't recede and that cane stays submerged for at least three to four days, there's a real possibility that that cane may die.
EMILY BOURKE: As the world's third-largest exporter of sugar, global sugar prices will be affected.
Steve Greenwood is from the peak industry body, Canegrowers.
STEVE GREENWOOD: Really importantly, there will be a lot of infrastructure loss, particularly - strangely enough - our irrigation infrastructure - pumps, pipes, roadways, railways, all that sort of stuff - that will be significantly impacted by this event.
EMILY BOURKE: And he expects some in the industry to call it quits.
STEVE GREENWOOD: Australian cane farmers, by their nature, are generally older. That is the age profile of our community.
For some of them, this might be the final straw where they go, "Oh, look, it really is time to get out", because it does come on top of a - the previous decade has been a reasonably tough one for them. The prices have been pretty low, so world sugar prices have been pretty low.
They've improved in recent times, but that said, we're still in a recovery phase, and there will be a number of growers, particularly those ones where there's been significant flooding impact on their farm, this may be the final straw for them.
EMILY BOURKE: Beef, sheep and grain producers have also been hit.
Ian Burnett is the general president of AgForce Queensland
IAN BURNETT: It is widespread, from the Fitzroy area in central Queensland extending down east of the Great Dividing Range - extensive damage and stock and crop losses throughout the eastern part and extending out to Chinchilla on the Darling Downs.
There are reports of quite large numbers of stock being swept onto fence lines and into catchment areas, and unfortunately they have perished.
EMILY BOURKE: Queensland's peak horticulture body has just started assessing the damage.
Alex Livingstone is from Growcom:
ALEX LIVINGSTONE: Some of the citrus orchards, and macadamias, avocados, have been hit, and for the next few days, we just need to sit back and let the water subside, because there will be product that will survive that and survive it very, very well - predominantly citrus.And we want to make sure that that product can then be harvested and get out to market and be sold, because after the 2011 floods there was perfectly good product which was left in the fields because people thought there was no citrus available.
EMILY BOURKE: And he says the damage bills are likely to run into the millions of dollars before production can return to normal.
ALEX LIVINGSTONE: In some instances, farmers will have copped all the expenses of planting those crops.
They may not be due for harvest for another couple of months, or even out til April, May, but they have taken the expense of planting the crop.So if they're lucky and things dry out, they'll be able to replant and still make their planting windows, but they will have to then reinvest in all the new seedlings and preparing the ground and all of that sort of thing.
So it's a financial hit.
A lot of the growers were only just getting back on their feet after 2011, and so it's going to be a very difficult pill for them to swallow.
