During their stay, police noted the group would spend a large amount of time in their hotel rooms, although Rush and Czugaj did make the most of their time in Bali and went shopping, eating, drinking and playing water sports. The group met again on 16 April for what police allege was a final briefing, before meeting for their final time at the airport before their 17 April arrest.
