The 2017/2018 Australian mango season was the biggest on record, with more than 10 million trays picked across the country for the first time.

The Northern Territory supplied the most mangoes to market, with a 48 per cent share of the national crop.

Queensland's farmers produced 47 per cent, and the remainder was made up by the other states, excluding Tasmania.

An increasing number of new mango trees maturing into commercial production was the main driver behind the record harvest.

Australian Mangoes CEO Robert Gray said newer mango varieties were making up an increasingly larger share of the national crop.

"The non-Kensington Pride varieties are really starting to be a much bigger contributor as those orchards that have been planted over the last 10 to 15 years start getting into full production," Mr Gray said.

"This is probably the first year that the combination of R2E2, Honey Gold, Calypso and Keitt contributed more than 50 per cent of the total production."

Given the large number of mango trees being planted across Australia, Mr Gray expected the national harvest record to be broken again in the near future.

"The trees that are producing that extra fruit are in most cases a way off achieving their peak production," he said.

"Year-to-year we may have some ups and downs, but over the next five years we are expecting that total crop number to continue to rise as increased production from all of those varieties continue to hit the marketplace."

Oversupply putting pressure on prices

The increasing amount of fruit in the market created a mixed price response across the season.

Mr Gray said while both early and late season mangoes received good prices, an oversupply mid-season pushed prices down for some regions.

"We did have quite an overlap in that late November, December period, so for growers in that Burdekin, Bowen, Mareeba region, some of their varieties came under quite a bit of price pressure this season," he said.

"There is obviously more work to be done in terms of an industry level of forecasting our supply to make sure that affect isn't substantial going forward.

"But that increased volume has been met with great consumer demand and fairly consistently high prices right across the 5-6 months of the mango season."

Mr Gray said the mango industry was trying to spread its supply across a longer period, so all farmers could benefit from good prices.

"So part of the reason we are able to make sure our values are being held strong is that the total volume is coming over a longer period of time," he said.

"One of the focus of industry is to grow our market in a way that delivers profit, to achieve that, getting that spread of supply is really critical."

The last mangoes of the 2017/18 season were picked in Gingin in Western Australia at the beginning of April.
