The communications, principally between the two accused, which occurred in the context of the four key events
- The Crown proposes to rely on the evidence of communications between the two accused and others overseas to show that both of the accused were receiving instructions as to what they should do in relation to the four key events. Because the communications between the accused and their brother, Tarek, were conducted over Telegram, an app which facilitated transient messaging, the actual communications with Tarek are not in evidence, although Telegram communications between Khaled and the Controller are included in the "Chat Summaries" folder which was marked Exhibit B on the voir dire. However, the Crown will rely on communications between the two accused which refer to their communications from Tarek as being evidence from which the jury will be able to infer that each of the brothers communicated with Tarek about a subject which concerned them both. The Crown identified examples in the volume of "Chat Summaries" of the evidence it proposes to adduce for this purpose.
- The Crown relied on communications between the accused about the delivery of the DHL package which contained a welder in which the IED was to be secreted. The Crown referred me to communications on and around 5-6 February 2017 which concerned how they could obtain the complete name and precise address of the cousin to whom the parcel was to be delivered so that the details could be communicated to Tarek. The Crown indicated that it relied on this evidence to show that the two accused were in contact with Tarek about the package that was being sent.
- The Crown also relied on the circumstance that a photograph of the waybill for the DHL package which was to contain the welder and the IED was on the phone of each accused, thereby establishing that each accused was aware of the package and was involved in its delivery to their cousin.
- The Crown proposes to adduce evidence that on 18 April 2017 it was Mahmoud who called DHL to make enquiries about the delivery of the package. When the operator asked him for a contact telephone number, Mahmoud gave him an email address for the purposes of communications concerning the package.
- The Crown indicated that it proposes to rely on messages between the two accused at around 20 April 2017 about their going home to open up the welding machine. The Crown case will be that the accuseds' purpose in opening the welding machine was to locate the IED. At around the time at which the communications indicated that they opened the machine, the two accused began communicating about the purchase of a timer, which, on the Crown case, would have permitted the detonation of the IED to be delayed until mid-flight. There were discussions between them about how and where to buy the timer and to which address it could be delivered.
- The Crown proposes to rely on the evidence that Mahmoud purchased a timer using his wife's eBay account which was then delivered to Khaled and, on the Crown case, to be fitted to the IED.
- Another category of communications on which the Crown proposes to rely is the communications between the two accused which show that they were both aware of the item of luggage which Amer intended to take with him on the flight. The Crown identified a communication on 14 July 2017 in which Mahmoud asked whether Khaled was sending anything with Amer. The Crown will rely on the cryptic nature of the discussion between them and the fact that the particular item was not identified in support of the inference that they were referring to the IED. The Crown also identified a conversation between Mahmoud and his wife in which Mahmoud instructed his wife not to go out into the yard because "Haj" (Khaled) "opened the mince machine which is sharp and no one touch it please". The Crown indicated that it proposed to rely on this conversation as evidence that Mahmoud knew that there was a dangerous item (the IED) inside the meat grinder and did not want his own children to be injured by it or to interfere with its operation by playing with it.
- There was also a series of communications between Khaled and the Controller via Telegram on 14 July 2017, being the day before Amer was due to take the Etihad airline from Sydney airport. These communications related to the assembly of the IED and other devices, such as the timer, which would make it operational as a bomb.
- The Crown also identified communications on 14 July 2017 between Mahmoud and Khaled about taking Amer to the airport on which the Crown proposes to rely in its case against Mahmoud to indicate that Mahmoud's lies in his recorded interview amounted to a consciousness of guilt.
- The Crown indicated that it proposes to rely on Mahmoud's admission in a telephone call to his wife that he was at the airport, "waiting for them".
- The Crown also proposes to rely on conversations between the two accused on 16 July 2017, the day after the flight in which Khaled explained to the Controller that the "gift" had to be taken out of the luggage because it was too heavy and that it had been taken home and "secured".
- Further conversations between Khaled and the Controller indicated that Khaled offered to take the item overseas next time he went but the Controller said that he was not to do that because he needed to remain "here" (presumably Australia) to "carry out the work here" (on the Crown case, terrorist activities). Later, the Chat Summaries recorded that the two accused joked about who was going to take "the machine" overseas.
- The Crown also relied on three-way chats between the two accused and Amer who, by that time, had arrived overseas. These discussions concerned a difficulty between Amer and his former landlord which gave rise to a fear on the part of both accused that Amer might have said something to the landlord which might have incriminated them.
