Australian farmers will plant more hectares to winter crops this season, but there will be less wheat and barley in the mix, according to the latest ABARES crop report.

The quarterly Australian Crop Report estimates a good start to the season seen in many growing regions will see Australian farmers; winter crop production jump 7 per cent, to 42.3 million tonnes, the highest since the 2011-12 season.

Despite planting less wheat, the nation's wheat crop is also expected to hit a four year high, rising 5 per cent to 24.5 million tonnes. A similar trend is seen in barley production, also rising 5 per cent to 9 million tonnes.

Canola growers have expanded their planted hectares by 4 per cent (2.5 million hectares), and ABARES is tipping production this season to hit 3.2 million tonnes, a 10 per cent rise.

Chickpea production is estimated at 1.1 million tonnes (up 8 per cent) off 717,000 hectares.

The rising productivity of Australian winter crops is all thanks to average to above-average rainfall percentiles across many grain growing regions in southern regions in March and May.

The Bureau of Meteorology is forecasting continued good conditions from June through August.

ABARES' prediction of a 25.4 million tonne wheat harvest is in line with international agencies forecasts, like the United States Department of Agriculture (24.5 million tonnes), the International Grains Council (25 million tonnes, National Australia Bank (26.1 million tonnes).

The rise in Australian production also fits a broader trend of bumper harvests, with the latest IGC report stating 2016-17 would see the "second biggest harvest ever" of grains across the globe.
