Hay Point Coal Terminal posted its highest coal export figure in three years as miners ramp up production to offset lower commodity prices.
More than 4.1 millions tonnes of coal was exported though the BHP Mitsubishi Alliance-owned terminal in June, up from 2.6 million in the same period last year.
Queensland Resources Council chief Michael Roche said higher coal exports showed companies were increasing volumes to maintain profitability, Daily Mercury reported.
"Companies know the way to make money at the moment is through volume because they're not going to make money through fat prices," he said.
"In the June quarter in Gladstone, Abbot Point, Hay Point and Dalrymple Bay ... all exports were up strongly on this time last year.”
Roche said the high export volume was evidence BMA had "got on top of its cost structure" but added that not all companies were in the same situation.
"We have ... some mines that have got on top of their cost structures and ... established a profit margin," he said.
"There are other mines that are yet to establish that margin of profit ... and there are mines and parts of mines that may well not get into profitability in this current environment."
Hay Point Coal Terminal is owned by BHP Billiton Mitsubishi Alliance, while Dalrymple Bay Coal Terminal, also at Hay Point, is leased from the State Government by DBCT Management.
