On a spring day in the year 1996, a lone gunman using semi-automatic rifles killed 35 people in the historic site of Port Arthur.
That massacre nearly thirty years ago, which sparked some of the most stringent firearm regulations in the world, can feel like a different era for many citizens.
However, the tragedy in Bondi this past Sunday, which claimed 15 lives, has revived the ghosts of the 1996 shootings.
A study released earlier this year revealed that there are now in excess of four million guns in private hands across the country – a figure that is nearly twice the amount from about 20 years ago.
This equates to approximately one firearm per seven citizens.
While Queensland has the highest number of legal firearms, followed by New South Wales (NSW) and the state of Victoria, it is Tasmania and the NT that have the greatest density of weapons.
The data also contradicts the popular notion that guns are mostly possessed by people in regional areas.
Weapons are widespread in cities and their outskirts, with a sizable percentage located in population centres.
Critically, there are now firearms concentrated among fewer owners, with the registered individual possessing several firearms.
Weapons legislation in Australia are not uniform across the country, with a mixed implementation of rules across states and territories.
Typically, to apply for a gun licence, an individual must be over 18, deemed a "responsible individual", pass a competency test, and provide a "valid purpose" for ownership.
The allowable purposes include recreational hunting or pest control, target or sport shooting, certain occupational requirements, and as a hobby.
However, significant gaps remain. For instance, young people in some jurisdictions can have supervision of a firearm from as young as 10 or 12 years old.
Following the Port Arthur massacre, a sweeping overhaul of national gun laws was enacted, leading to a large-scale surrender scheme of over 650,000 firearms.
Certain types of firearms were outlawed, and security screenings alongside waiting periods for sales were introduced.
A key tenet of these reforms was the elimination of "self-defence" as a acceptable grounds for gun ownership.
In the immediate aftermath the Bondi shooting, political leaders were forceful about the need to tighten gun laws.
A country-wide firearm surrender program was announced, marking the first such effort since 1996.
Other proposals now under consideration include:
There are also calls for ongoing evaluations of existing licence holders, acknowledging that "individuals can be radicalised" over time.
These proposed changes have met with opposition from some quarters.
Pro-gun advocates contend that restricting ownership would not have stopped an attack driven by radicalisation.
They suggest that political capital would be better spent improving intelligence rather than restricting lawful owners for the great bulk of responsible owners.
Furthermore, a critical reform from 1996 – a centralised weapon tracking system – remains incomplete, though it has now been listed as a urgent task.
For campaigners, the Bondi attack is a horrific reminder that gun laws must keep pace with changing times.
They argue that modernisation is needed to "keep up-to-date" and prevent future tragedies.
While mass shootings remain uncommon in Australia compared to some nations, the threat persists, and the challenge of firearms circulating illegally – through poor storage – continues to pose a danger.
As one advocate reflected, "It is regrettable that it takes such a loss of life to get people to wake up and take notice."
