The Australian laws and NZ laws do not allow you to be armed either in public or in your own home. It is illegal to have a firearm for self-defence and any attempt to use one for such purposes will land you in prison with a hundred thousand dollar legal expense and your gun licence cancelled. Firearms must be locked in safe's and so does ammunition in a separate locked facility. There is no way that anybody during a home invasion could have a firearm ready for a home invasion and not be committing a "crime". And you know that.
While the law says it is illegal to solely have a firearm for self defense; a firearm can be used for self defense. Yes, you're right in that firearms and ammunition must be locked up. However, I know there are people who don't do that. Regardless, it's just not necessary as the threat doesn't exist, with the odd very, very rare exception. House thieves don't carry firearms and will bolt if they're disturbed. The rival criminal gangs shoot each other now and again, all most always over drug control such as meth. The public don't seem mind that at all.
