In an emergency, every second is critical, but what happens when emergency services cannot find the person who needs help?
Two Riverina first responders have urged residents to have plans and measures in place, warning that the time to call triple zero is never planned.
NSW Ambulance Inspector Eamonn Purcell said there are common problems paramedics face when getting to their patients.
For instance, residents or visitors who decide to go out to The Rock Reserve often do not know their specific location.
"They might think they are only 200 metres from the car park, but often we get there, and it becomes a bigger operation because they are two kilometres from the car park," Inspector Purcell said.
"Then it becomes a multi-agency rescue operation."
Inspector Purcell said sometimes paramedics are given the exact address to a home in Wagga, but it could be hard to find if the street number is not displayed correctly.

This challenge is exacerbated even more in the dark.
"What we will do as part of the call taking process is we say to the caller 'go turn your front porch light on', and that helps us when we are looking down a darkened street," Inspector Purcell said.
"We encourage people to make sure the number of their property is visible so when we want to get there in a hurry, we can find them.
"Another issue we have is when people are travelling around the region, and they know they are between Tumut and Gundagai, but they don't have the nearest cross street or suburb."
Inspector Purcell encouraged residents to use the Emergency+ app, which has been developed by Australian emergency services, government and industry.
It helps to ring Triple Zero and provides the person with their GPS coordinates.
"Those bits of information means a more timely response, and we can get to you without delay," Inspector Purcell said.
"In terms of a cardiac arrest, seconds count. We want to get there as soon as possible.
"I know people do not get up in the morning and think 'today I am going to call the ambulance' ... but we would encourage people to think about when they might need an ambulance."
Fire and Rescue zone commander Stewart Alexander said it was critical for emergency services to get the most accurate location as soon as possible.
"When people are calling triple zero, they are likely to be very stressed, so it's important to have easy access to the information," he said.
"It can be tough to concentrate and convey your thoughts, particularly when it's a family member or loved one involved.
"The Emergency+ app also has the 'what3words' feature that divides the whole world into three-metre squares and gives each one a unique three-word identifier which can be used in a remote area."
Superintendent Alexander encouraged parents to teach their children the important information to give emergency services such as the nearest cross street, suburb, and other helpful factors.
"Time is critical, and the more information that emergency services receive can be lifesaving," he said.
"Always make sure to call triple zero to report emergencies. Don't ring us directly."
The Emergency+ app is free for iOS and Android devices through the Google Play and Apple stores.
