A massive clean up operation is continuing along beaches throughout Port Stephens, following Friday's shipping mishap.
A huge amount of debris is still washing ashore from more than 80 containers that fell overboard from cargo ship YM Efficiency during rough seas off Newcastle.
The 12m containers were mainly full of general household items, however some contained mountain bikes, scooters and even a couple of dual-cab utes.
Authorities say most will end up on the sea floor.
"The containers still floating around are likely to stay in a semi-submerged state for a period time and depending on how damaged they are, they'll sink to the bottom. The vast majority will be lost forever," RMS director Angus Mitchell said.
Jimmys Beach at Hawks Nest was among the worst affected areas, with volunteers picking up huge amounts of rubbish.
Debris also washed ashore at Rocky Point near Anna Bay and Fingal Head.
Jimmys Beach also suffered further erosion following several days of large waves pounding the coastline.
Two locations along The Boulevarde have been impacted, leaving residents with beachfront homes on edge.
"There is certainly a nervous feel right through the community, it's very unsettling for those who live along there," Gordon Grainger from the Myall River Action Group said.
Stockton Beach also suffered severe erosion, prompting renewed calls for a long-term solution.
