In its final report for the year released today, 50.1% DBCT owner Prime Infrastructure Holdings said the terminal shipped 63.1 million tonnes, significantly lower than its 85Mt per annum capacity.

Prime said the shortfall was not due to any operational issues at the terminal.

About a month and a half ago, a DBCT Management spokesperson told ILN the rail feeding the terminal was running at about 72Mtpa.

At the time a second-stage prefeasibility was underway with terminal management receiving numerous non-binding requests totalling an extra 83Mtpa of capacity.

But binding agreements will not be made until a new access undertaking takes effect.

The Queensland Competition Authority is reviewing the draft access undertaking proposal to expand capacity at the terminal, and a final decision is expected before the end of this calendar year.
