Sorghum has taken a hard hit, with farmers forced to bale some crops for feed.
Agronomist Jim Hunt said crops planted in October suffered from low soil moisture and the summer heat while those planted in late 2018 missed the worst of it.
"The earlier sown crops flowered in the middle of the heat and the grain filled in the middle of the heat so they suffered the most, so yields were more than half of expected," he said.
But overall, it was a tough season.
"A lot of crops didn't make head. A lot of it was baled. More than what we'd normally do," Mr Hunt said.
"[The conditions] drastically reduced the area of sorghum and some people didn't plant at all."
Fellow agronomist Matt Roseby said crops planted in late November and early December "looked pretty good" until Christmas, then "the heatwave in January cooked them".
"Anything that was planted on the back of that November or December rain has been cut for hay or been grazed off," he said.
"Cattle have been going on sorghum paddocks behind the header to try and maximise feed value out of what was left of the crop as well.
Mr Roseby said yields could be "anywhere from a tonne and a half or four tonne to the hectare".
While the weekend rainfall came too late for sorghum, Mr Hunt said it was good news for primary producers.
"It's an ideal time for forage [crop]s - oats, winter wheats, dual-purpose barlies and forage brassicas," he said.
"Some people are sowing forage now. They've taken the opportunity because they've got enough moisture to establish forage corps, but it is a bit early for grains ... We need a lot more rain to fill [soil] profiles.
While Mr Roseby welcomed the recent deluge, he said it was "nowhere near drought-breaking" and follow-up rain was essential for farmers looking to plant winter crops.
"The key will be getting some follow-up rain towards the end of April - that will kick us right off with canola planting and barley wheat," he said.
"Fifty millimetres would help."
