In the documents,filed in the High Court on Monday,Mr Zhang's lawyers reveal that the warrants relate to conduct that allegedly took place between"about 1 July 2019 and 25 June 2020".

The documents state that Mr Zhang and others,who are not named,were allegedly"acting on behalf of the'Chinese State and Party apparatus'in a'private social media chat group and other fora'with Mr Moselmane,to advance the interests and policy goals of a foreign principle,being the Chinese government,in Australia."

Mr Zhang is accused of advancing CCP interest by"providing support and encouragement to Mr Moselmane for the advocacy of"Chinese State interests."

The documents further reveal that the AFP allege that Mr Zhang was"reckless"to the fact that his conduct"would influence the NSW branch of the Australian Labor Party’s policy positions and the views of members of the NSW electorate on China,and that part of the conduct was covert,in that it involved communications over a private social media chat group."

Mr Zhang's lawyers,Sydney-based legal firm Nyman Gibson Miralis,claimed the warrants"lacked clarity"and should be deemed invalid,arguing that it was unclear"whether the target was Mr Moselmane,the NSW branch of the ALP,or members of the electorate as a whole".

They also argued that the foreign interference provisions breach the implied freedom of political communication in the Australian Constitution.

The legal application also confirms that Mr Zhang is seeking to prevent the AFP from relying on evidence seized during the three raids by claiming parliamentary privilege over the material and is seeking an order that it be returned or destroyed.

The material he has claimed parliamentary privilege over includes:"all items obtained from a shared computer used by Mr Zhang during his employment and from server files related to Mr Zhang's parliamentary email account".

Mr Moselmane has also claimed privilege over materials seized on the raids of his home and office. On Wednesday,the Legislative Council referred the matter to the upper house privileges committee to determine the validity of the claims.

Mr Zhang,an Australian citizen who emigrated from China in 1989,first drew public scrutiny in September afterThe Sydney MorningHeraldrevealed he had completed a propaganda training course in Beijing run by the Chinese Communist Party in 2013.

Mr Zhang attended an event at the NSW Parliament's Jubilee Room in June 2018 where Mr Moselmane gave a speech proclaiming that China needed to"force a change to the rules and create a new world order” to realise its potential.
