The Port of Newcastle remains the economic and trade centre for the resource rich Hunter Valley and for much of the north and northwest of New South Wales. Newcastle is the world's largest coal export port and Australia's oldest and second largest tonnage throughput port, with over 3,000 shipping movements handling cargo of 95.8 Mt per annum, of which coal exports represented 90.8 Mt in 2008–09. The volume of coal exported, and attempts to increase coal exports, are opposed by environmental groups.
