AU$7 million (US$5.5 million) has been committed to investigate potential channel and turning basin works at the Port of Broome before the 2019 cruise season.
Kimberley Ports Authority (KPA) CEO Kevin Schellack said up to 70,000 cubic metres of material may need to be removed from the channel.
An additional 15,000 cubic metres of material may also be removed adjacent to and north of the wharf.
“Channel work investigations are in the early stages and consultants BMT JFA have provided a scope of works and listed the feasibility studies required before the extent of works can be fully identified,” said Schellack.
The work is being done as Carnival Line returns to homeporting at Fremantle in 2019.
It has stated it would like to access the Port of Broome wharf for longer periods and outside of current tidal limits.
