In the Tiwi Islands, the most significant impact was disruption to communications and power supplies. The telephone service throughout the Tiwi Islands was shut down for over 24 hours. The radio and television reception was interrupted by heavy rain and lightning, and the power supply in Pirlangimpi (Garden Point) was cut by fallen trees. Around Bathurst Island and northwest Melville Island, there was extensive damage to vegetation in exposed areas. Minor coastal erosion occurred in Milikapiti, where waves rose up to 4 metres (13 ft) above water level. In Pirlangimpi, many large trees were uprooted and several houses were slightly damaged. In Nguiu, Bathurst Island Township, some trees were blown down but there was no significant damage.
