There's even more to the story, every step even more absurd than the other:

US woman caught with golden gun in luggage at Sydney airport jailed for a year
US woman backflips in court, pleads guilty to smuggling 24-carat gold gun into Sydney

A review of Goodson’s phone revealed she had searched online “can I have a gun in my suitcase?” and set a calendar entry with a note reminding her to “put gun in suitcase”.

“What about the gun in your bag?” she was asked by a customs officer. Goodson replied: “Oh yeah, I forgot about that.”

"I am scared of shooting it... I would probably just pistol whip until I got training again," she said.

The court also heard that she previously owned two other guns while living in the States, but she had accidentally given them away. "Those guns I ended up giving away, because I accidentally left them in a donation box."
