Over the long weekend, Canberrans and Sydneysiders flocked to Cowra to take pictures of the brilliant yellow oceans of flowers blooming in abundance because of the rains.

"This group came from Sydney just to take a picture of the canola and then go home," farmer Lachlan Graham said.

"I've noticed Canberra number plates pulling up," farmer Douglas Houston said.

"It's been a phenomenal year. It's just been a fantastic season," Mr Graham, who is an agronomist as well as a farmer, said.

"With the rolling hills, it's a beautiful patchwork quilt. You've got the bright yellow of the canola crops, the green of the wheat and barley and the odd paddock where there's the purple of Paterson's curse," Mr Houston said.

"We've had a bunch of tourists coming just looking at paddocks. They love it. There must be something about the yellow flower which just intrigues people."

There were 2160 visitors in the Cowra Visitors Centre over the weekend. Normally, they get no more than 200.

It seems that city people from Canberra and Sydney, perhaps suffering from cabin-fever because of the lockdown, have seen Cowra's golden fields of canola as the new destination.

"We had so many people coming just for the canola that we did up a conola touring guide for them," Kurt Overzet of the Visitors Centre said.

"It's been a massive draw."

The new breed of canola tourist wants to get into the fields to be photographed, surrounded by the sea of yellow. Some farmers are irritated that townies just think crops can be walked into and gates opened - but overall, the city folk were welcomed.

Photographer Glenn Daley said he has done about 30 photoshoots with tourists and canola.

"It's quite a phenomenon. There's been a push to get in among the canola," he said.

"People can't get away interstate so short trips from Canberra and Sydney are very attractive," he said.

If you fancy going, the season only has a couple of weeks to run, according to Lachlan Graham.

He said the early varieties of the crop had come and gone and now only the late varieties were blooming.

Farmers either harvest the crop to sell to be turned into oil or let sheep graze it. This season has seen a lot of grazing because the price of sheep meat is high.

It was too early to say if abundant canola for tourists also means abundant profits for canola farmers.

Mr Graham was optimistic, though. "Until it's in the bag, we are left with our fingers crossed. At the moment, prices are looking reasonably good."

But he added: "Canola's good. Wheat's also good. We've got some good pulses. If we keep getting bits of rain, we should be in a good spot."
