Opinions about gun laws in Australia can be divisive.
While the regulations brought in under the National Firearms Agreement 1996, in the wake of the Port Arthur massacre, have successfully reduced the rate of gun-related deaths, people who use guns regularly - farmers, recreational and professional shooters, for example - say the laws go too far, restricting licence holders who have gone through strict checks from accessing certain firearms.
The Australian Crime Commission estimates there are over 2.75 million registered gun owners in Australia.
Yet many people are unlikely to have ever seen a gun, let alone fired one.
This week, Insight is looking at whether gun control is still working in Australia, 20 years on from the Port Arthur massacre.
We asked our studio audience whether they'd had any experience with guns, and for their thoughts on the current regulations.

"I grew up in the country where guns are a useful tool, and learnt gun safety at a young age.
My daughter (13 yrs) is a competitive shooter- she's already a better shooter than me! I'm not concerned about her. I think it's one of the safest sports in the country.
I think the gun laws need a lot of improvement. They target law-abiding people. Firearm owners are actually the best people in the country because they have to go through so many checks. They don't target criminal users."

"I'm vegetarian so I'm against even the legal forms of gun use, for hunting.
I don't know too much about the laws, but I think they're too lenient."

"I've used a gun at a rifle range. It was a unique experience.
I enjoyed it: the speed and precision. But only in a strictly controlled environment."

"I think the American gun laws are crazy - I'm glad we don't have them here!
Guns aren't something I worry about in Australia, but in the hands of the wrong person I do worry."

"I shoot - when I'm back in the States I visit the LAX shooting range. I've done some hunting but mostly I use it in the range or for security purposes.
It feels pretty powerful to shoot a gun. That first shot with a pistol, you realise it's small but actually very powerful. To actually aim and hit a target is not easy.
In general, I think the Australian laws work. I definitely think there needs to be a lot more governing in the US. To sit there and claim constitutional rights - it's not about taking them away, we're talking about regulation."

"My great-grandfather was one of the great game-snipers of Saskatchewan, Canada. But I've never shot a gun."

"I believe our environment with gun laws is good, compared to the US. I'd definitely be concerned to go to the US."

"I've been in the cadets for seven years so I've done some reasonably regular shooting. I think rifle shooting as a sport is demonised and isn't recognised for how challenging it is.
I've looked into getting a gun licence but the process was too difficult. I think gun laws are a bit archaic - they should be loosened. Not to the US-level, but small calibre rifles should be more accessible."

"I don't know if we need to take every gun away … although I can say this now, but what happens when there's another shooting, or massacre?"
