Being prepared for a disaster is second nature to KY Furneaux.
The survival expert, TV host and stuntwoman from South Australia has even written a book on the subject and admits she is a 'big nerd' when it comes to these things.
Her approach to preparing for a major disaster in an Australian city is simple.
And it's not about hoarding stuff in the basement.
Mareaux believes Aussies should focus on being able to leave their location if necessary – and carrying a few key items rather than lugging supplies around.
“A good example of this is having a water filter or life straw instead of 20 liters of water,” Ms Furneaux told Daily Mail Australia.
'This way you have access to almost 2,000 liters of clean drinking water with something as small and light as a chocolate bar.'
When disaster strikes, the first thing you should do is get yourself out of harm's way.

In an urban environment, this usually involves listening to warnings from authorities, who can nominate a safe zone when you leave the house.
Mareaux said water filters should be packed in a backpack called a “bug-out bag” or “go-bag,” which covers the four basic needs of water, fire, shelter and food.
Other items in her survival kit include a vessel for drinking water, all resistors, emergency blankets, plastic ponchos, ration packs and a headlamp.
“With a go-bag already packed in an easy-to-access location, you can save precious minutes getting to safety,” she explained.
Once those basic needs are covered, you can grab other last-minute items including identification documents, a will, insurance papers, hard drives and USBs.
In a disaster, you have access to many more resources if you can stay home.
But you have to be prepared to lose electricity and running water.
“People start to panic about charging their phones, when in reality they have to think about the fact that water isn't going to be pumped into your house and the food in your refrigerator will quickly start to rot,” Furneaux said.

She recommends researching the history of natural disasters in your area and creating an action plan with your loved ones.
But why prepare for the unthinkable?
Mareaux believes having a plan will help Aussies cope with the extreme stress of a disaster.
“Having a go-bag and an emergency evacuation plan means you can stay calm, think rationally and have a better chance of protecting your family and friends when the unexpected happens,” she said.
'People associate preparing for natural disasters with being scared or pessimistic when in reality it prevents fear and bad outcomes.
'There's a saying: “Prepare for the worst but expect the best.” When I'm prepared, it actually allows me to focus on the good things in life, knowing that I can take care of myself if something goes wrong.
“Unfortunately, it usually takes a natural disaster for people to become proactive about preparing for future ones and by then it may be too late.”
When she's not preparing for the apocalypse, Furneaux racks up an impressive list of film credits as a stunt double, joining the likes of Anne Hathaway and Jennifer Garner.
She is currently working as a survival consultant for a new film, although the project remains “top secret” for now.
