372 In an incident report (Ex R79 (at 2)), Mr Payne explained Mr Lehrmann left a "Top Secret - Codeword classified document uncovered and uncontrolled on a desk". When this was brought to Mr Payne's attention, Mr Payne informed Mr Lehrmann documents at that classification level could not be handled in such a manner and offered to provide him with appropriate document handling procedures. Mr Lehrmann declined and thought Mr Payne was straying outside his lane. He requested Mr Payne give him the document in order for him to return it to the originating agency, claiming he had a secure means by which to transport it. He was then observed leaving the Minister's Suite with the document in an opaque plastic folder (which, hardly surprisingly, was not consistent with appropriate procedure).

376 Ms Higgins was invited along separately by Ms Gain, whom she had known for a couple of months (T610.15–19). She viewed the event as a networking opportunity, and a chance to demonstrate to her professional peers she "wasn't just a receptionist" and she had "contacts" (T610.31–35). Ms Higgins extended the invitation to a number of others, including Mr Wenke (who worked for the Minister for Home Affairs and occasionally socialised with Mr Lehrmann), Mr Lehrmann and a man she was in contact with on the dating application Bumble, who also worked in politics (T610.37–40; T611.1–9). Ms Higgins' hapless date was
