Almost a year ago on October 7, Hamas - designated a terrorist group by the Australian government - attacked Israel, killing 1200 people and taking more than 200 hostages, according to Israeli authorities.
The attack sparked an Israeli offensive in the Gaza Strip that has killed almost 42,000 Palestinians, according to local health officials.
The conflict recently spilled over into Lebanon with the Israeli army responding after the designated terrorist group Hezbollah fired hundreds of missiles at the nation.
Israel's military said on Saturday it had killed Hezbollah leader Hassan Nasrallah in an air strike on Friday.

In Australia, demonstrators are preparing to gather on Sunday at the State Library in Melbourne and Sydney Town Hall, and in smaller cities and towns, to protest the escalation of the conflict.
The Australia Palestine Advocacy Network is calling on Australians to support the Palestinian people on a National Day of Action for Gaza, featuring rallies in major cities and the launch of a month of action.
Jewish communities will hold a series of events to observe the anniversary of the October 7 Hamas attack which Zionist Federation of Australia chief executive Alon Cassuto said carried an immense weight of grief and despair.
"As a community, we will come together to mourn the greatest loss of Jewish life in a single day since the Holocaust, and, as we have done every single day since October 7, call for the remaining 101 hostages to be freed from Hamas captivity," he said.
"Despite the profound sadness and the sheer scale of hostility, anti-Semitism and fragmentation of social cohesion in Australia since October 7, the Jewish community has never been stronger, more resilient and united."
Foreign Minister Penny Wong used a speech at the United Nations at the weekend to call for a clear timeline for Palestinian recognition, saying peace in the Middle East was the only way to break the cycle of violence.
Australia Palestine Advocacy Network president Nasser Mashni said Australia had dragged its feet in responding decisively to the conflict.
"People of good conscience across this continent will come together to demand the Australian government act with integrity and immediacy to help put an end to Israel's brutality," he said of Sunday's rallies.
