The embattled miner won support from shareholders to delist itself from quotation on the Australian Securities Exchange (ASX), which means its shares won't be able to be bought or sold on the public exchange.

Crucially for the community and for environmentalists, it means Wollongong Coal no longer has a legal obligation to inform the ASX of any information which may "materially" affect the share price.

This has been one of the few sources of information about what is happening within the publicity-shy miner, owned by Indian parent conglomerate the Jindal Steel and Power group.

"WLC has been suspended from trading since December 2018," chairman Milind Oza told Tuesday's annual general meeting, according to a copy of the speech released via the ASX.

"There has been virtually no liquidity in WLC's shares on the ASX or otherwise for an even longer period.

"WLC has been unable to use its listing on the ASX to raise fresh capital and to repair its balance sheet because of the low levels of liquidity and investor interest.

"[And] delisting of WLC will also save listing costs."

The miner told shareholders the listing compliance and registry costs were about $80,000-$90,000 per year.

The company had earlier said it would "still be subject to a continuous disclosure regime"; it must inform the corporate regulator ASIC. It said it would also upload the information to its website.

Wollongong Coal told the ASX its bid was successful, with just 3.17 per cent of share votes directed against the delisting proposal. Most shares in the company are held by the Jindal Group.

Protesters gathered outside the AGM to urge NSW planning authorities not to let the miner expand under the water catchment, saying its corporate performance showed it could not handle the responsibility.

WLC shares will remain at 0.8c where they have sat since December 2018.
