Billionaire Huang Xiangmo's political influence has extended directly into the NSW parliament with revelations that a serving NSW MP filed documents for an organisation headed by the Chinese Communist party-aligned businessman while acting as its adviser.

Labor MP Ernest Wong filed and signed off on financial documents for the Australian Guangdong Chamber of Commerce (AGCC) headed by two major Labor donors, including Mr Huang.

Mr Wong also listed his parliamentary email on the NSW Department of Fair Trading documents he lodged on behalf of the AGCC in November 2014.

Mr Wong filed the documents even though the organisation is directed by several wealthy businessmen, including at least two multimillionaires, with ready access to lawyers and translators.
