The Coalition government if re-elected will commit $24 million to the ongoing upgrade of the Cairns Marine Maintenance Precinct.
Prime Minister Scott Morrison is set to announce the funding for stage two of the upgrade in Cairns on Thursday, taking the total investment in the upgrades to $48 million following completion of stage one.
Mr Morrison said the new investment in the precinct would create hundreds of jobs, support the tourism industry and strengthen Australia's border security.
"The Cairns Marine Precinct is the place to go for maritime services and this investment will ensure it can meet the growing tourism, marine industry, and naval demand," he said.
"With the Great Barrier Reef a boat ride away, this will also make Cairns an even more attractive launch pad for private and charter boats, yachts and superyachts keen to explore the region."
Member for Leichhardt Warren Entsch said the Morrison government had worked with local operators to design the wharf, and ensure it was fit for purpose.
The stage two works will include additional naval certified hardstand areas, all-weather vessel servicing capabilities, additional docking facilities, longer wharfage to meet in-water maintenance support requirements, improved workshop facilities, plus offices, parking and other amenities.
