The woman and her three-year-old and five-year-old children went walking around lunchtime on Saturday but did not return, and did not have a personal locator beacon on them.
They were eventually found fatigued and dehydrated just before 1:00am.
Police said the incident highlighted the importance of carrying extra supplies of water and safety gear, even when people were going on a short walk in bushland.
"In this situation a personal locator beacon could have been used to alert authorities to the fact the woman and children were in danger," a police spokesman said."The beacon would not only alert authorities to the situation, but provide the exact coordinates of where the missing stranded people are — which means the time taken to rescue them is a lot less.
"Even highly experienced bushwalkers who are familiar with the area they are in can experience unexpected trouble, so we recommend anyone planning camping or bushwalking activities consider just how important a personal locator beacon can be for them."
