Hi there. Hoping someone can help. My wife works in Australia for a UK based Plc who is about to commit to a contract with a mid-size publicly listed US tech firm. The contract is sizeable and will be very good news for the tech firm. The deal has been communicated internally as being market sensitive, as both firms are listed, although it's not completely confined to upper management and the company is pushing ahead with various integration projects ahead of the deal being signed. A senior member of the management team in Australia has openly claimed several times to various people in my wife's office to have bought shares in the tech firm following the internal announcement of the deal, even stating their motives for doing so as being directly related to the contract being signed. Is this legal under Australian law and does my wife (and her colleagues) need to declare that these claims have been made to her? She's not sure where she stands if this is indeed illegal ( insider trading?) and she is later discovered to have had knowledge of her manager's purchase of shares. Thanks for your time and any input.
