The SA Minister for Planning has released for public exhibition Kangaroo Island Plantation Timber's revised Smith Bay jetty plan.
KIPT's addendum to its draft Environmental Impact Statement for the proposed KI "seaport" at Smith Bay can now be read online.
The revised marine design is on public exhibition until Friday, December 20.
The planning department will conduct a drop-in session at Kingscote Town Hall on Friday, November 29.
KIPT released a statement to the stock exchange stating it understood that the minister would only consider new comments in relation to the revisions to marine structures.
Yumbah Aquaculture director, Anthony Hall said Yumbah would assess the detail of this amended proposal, and would be making a submission in response.
"But the reality is that while Kangaroo Island Plantation Timbers wants to believe its latest wharf design solves every problem for Yumbah, that's just not the case," Mr Hall said.
"The South Australian Government must make a choice for Smith Bay: KIPT's 650-metre long industrial wharf or Yumbah's world-class aquaculture business of 30 years. It can't have both.
"If a seaport proceeds at Smith Bay the impact on-shore and off-shore will destroy Yumbah at Smith Bay. We can't make that any clearer
"If the State Government insisted KIPT adequately assess and select one of the many other more appropriate sites for this project, as Kangaroo Island Council has argued, aquaculture can flourish, KIPT can send its logs and woodchips off the island - and KI wins twice."
KI/VH Dolphin Watch, mayor Michael Pengilly and Eco Action KI have also stated the new jetty does not alleviate their concerns about impact to marine life and the impact on the north coast.
KIPT in its statement remains optimistic and "looks forward to explaining the benefits of the changes that it has made, and to bringing the lengthy development assessment process to a satisfactory conclusion".
The company meanwhile on November 6 issued another statement to the ASX stating the Supreme Court had just heard a case where the company was seeking easements affecting a dam and electricity access.
A judgement was pending and the company had not been able to settle the matter before trial, but that the easements did not impact on its ability to build its development, the statement read.
KIPT then released an additional statement to the ASX on November 8 that it had a memorandum of understanding with Lucas Total Contract Services with a view to entering into a contract for the "landside civil works and construction".
