Families heading away for Easter have been urged to take care in ACT parks, with rangers anticipating increased visitor numbers during more dangerous than usual conditions.
More rain was forecast for Saturday with the chance of a thunderstorm in the ACT, creating a flood risk in some parks and reserves over the Easter break.
ACT Parks and Conservation Service's Daniel Iglesias said people should take extra precautions in the event of wet weather in already saturated catchments. "Streams and creeks are full of water and flood waters can occur suddenly and without much warning," he said.
"Strong winds and flood waters are dangerous and will move fallen trees unpredictably."
Mr Iglesias said some areas had been impacted by extended periods of heavy rain over summer. He said extra precaution should be taken, regardless of levels of experience in the outdoors.
"Namadgi National Park is a part of the Australian alpine area, which means conditions can change and deteriorate very quickly," Mr Iglesias said.
"If you're not completely comfortable and prepared for your trip, stay closer to home and consider coming back another day when the weather improves."
The ACT safety warning follows the death of two bushwalkers in NSW's Blue Mountains on Monday.
A father and his nine-year-old son were killed by falling rocks during a landslide while walking at Wentworth Falls.
The man's wife and their 14 year-old son were badly injured in the incident.
NSW National Parks and Wildlife closed most trails in the Blue Mountains this week while a safety review was under way. The park remained closed on Friday due to bad weather conditions.
Heavy rainfall forced the temporary closure of areas and tracks within several South Coast national parks on Friday, including areas in Meroo, Murramarang, Deua, Mimosa Rocks, Eurobodalla, Golaga and Bournda.
NSW Parks director Kane Weeks said while most parks on the South Coast were currently open, some areas were closed due to hazardous weather conditions.
"Some walking tracks are currently closed and may require some maintenance before we can reopen them. Creeks and rivers are expected to increase in level and may have strong currents," Mr Weeks said.
"Water crossings during these conditions may be extremely dangerous.
"National parks are by their very nature, wild and remote places. We want people to enjoy themselves while also respecting the unpredictability of weather and changing conditions."
ACT rangers said closures to parks and reserves could occur at short notice and visitors should check the ACT Parks website before travelling.
ACT Parks advised they would assess the impact of extended rainfall on the environment and park assets over the coming days.
