On a Sunday afternoon in 1996, a single attacker armed with rapid-fire weapons took the lives of 35 people in the Australian tourist town of Port Arthur.
That horrific event nearly a generation ago, which ushered in some of the most stringent firearm regulations in the world, can seem like a bygone age for many residents.
However, the tragedy in Bondi this past Sunday, which claimed 15 lives, has brought back painful recollections of the Port Arthur massacre.
A recent report revealed that there are now more than four million guns in private hands across the country – a figure that is almost double the amount from about 20 years ago.
This means approximately a weapon for each small group of people.
While the state of Queensland has the largest arsenal, followed by NSW and the state of Victoria, it is Tasmania and the NT that have the highest rate of firearm ownership.
The data also contradicts the common view that guns are mainly owned by rural residents.
Firearms are prevalent in metropolitan and suburban areas, with a large share located in population centres.
Critically, there are now firearms concentrated among fewer owners, with the typical gun owner possessing over four firearms.
Firearm regulations in Australia are varied across the country, with a patchwork implementation of rules between different jurisdictions.
Generally, to apply for a gun licence, an individual must be an adult, deemed a "fit and proper person", pass a safety program, and provide a "genuine reason" for ownership.
The accepted reasons include sport shooting or animal management, competitive shooting, certain job-related needs, and for collections.
However, significant loopholes remain. For instance, young people in some jurisdictions can have use of a firearm from as young as early adolescence.
Following the Port Arthur massacre, a sweeping overhaul of national gun laws was enacted, leading to a voluntary hand-in of over 650,000 firearms.
Automatic and semi-automatic rifles were banned, and vetting procedures alongside waiting periods for sales were introduced.
A key tenet of these reforms was the rejection of "self-defence" as a justifiable cause for gun ownership.
In the hours following the Bondi shooting, political leaders were unequivocal about the need to strengthen gun laws.
A country-wide firearm surrender program was proposed, marking the largest such effort since 1996.
Other suggested measures now under consideration include:
There are also calls for ongoing evaluations of existing licence holders, acknowledging that "individuals can be radicalised" over time.
These swift actions have drawn criticism from some quarters.
Pro-gun advocates contend that imposing caps would not have stopped an attack driven by extremist ideology.
They suggest that focus would be better spent combating radicalisation rather than changing laws for the vast majority of responsible owners.
Furthermore, a key proposed reform from 1996 – a centralised weapon tracking system – remains not yet operational, though it has now been listed as a key project.
For long-time advocates, the Bondi attack is a tragic indication that regulations must evolve with technological advances.
They argue that reform is needed to "remain effective" and safeguard communities.
While mass shootings remain uncommon in Australia compared to some nations, the potential persists, and the legacy of firearms circulating illegally – through black markets – continues to pose a problem.
As one advocate reflected, "It's sad that it needs such a devastating event to focus attention and pay heed."
