Tonight, Cathy and Luke get their first taste of the Cape at a house opening ceremony in Aurukun, get their feet wet hunting mudshells in a mosquito-infested swamp, launch a community-built catamaran to explore the wetlands and try not to get burnt to a cinder as they learn how to set fire to country

In tonight's episode Cathy and Luke hunt down sand frogs that drink their own urine and start a fire with nothing but a bit of old wood and some combustible roo poo. Luke puts his new-found confidence to the test on the dance floor and Cathy tries some tongue-twisting rap with the kidz in the hood in Tennant Creek.

Going Bush is back! So roll up your swags, pack your sense of adventure and hit the road with Olympic Champion Cathy Freeman and actor Luke Carroll as the two city clickers embark on a road trip through remote Indigenous Australia.

The fourth episode of Going Bush is the powerful climax of Catherine and Deborah's four thousand kilometre life-changing journey across the top of Australia. Crossing into Arnhem Land, the biggest Aboriginal reserve in the country, the girls hit the high notes with indigenous rock band Narbelek, discover an isolated community weaving its way to economic success, and sweat out the dust and grime of weeks on the road in the ultimate bush sauna.

The ninth Bible plague meant three days of darkness, nowadays commonly believed to have been caused by a sandstorm. Sandstorms have ravaged the face of the earth for millions of years and transformed entire continents. Grains of sand from deserts are often blown huge distances, carrying with them not only fungi and viruses but also pollutants and environmental toxins. Beijing suffers particularly badly from violent sandstorms and the Chinese government has launched an ambitious program of prevention.

This four-part series looks at what happens when two of Australia's best-known women, Olympic champion Catherine Freeman and actor Deborah Mailman, go bush across the top end of Australia together. The series captures the experiences of these two self-confessed city girls and is a rollicking ride that captures the quintessential tourist experience of outback Indigenous Australia. It is a journey of physical, cultural and personal exploration and not just for Deborah and Catherine.

To punish the Egyptian Pharaoh for enslaving the Israelites and refusing to let them leave, God sent down ten plagues on Egypt. The fourth was the plague of locusts. Hans-Joerg Ferenz of the University of Halle in Germany is researching ways of combating locust plagues and has found, that under certain conditions, solitary locusts develop into swarming locusts.

According to the Bible, to punish the Egyptian Pharaoh for enslaving the Israelites and refusing to let them leave, God sent down ten plagues on Egypt. "For the Seventh plague, God sent several storms. Thunder and lightening and hail flashed down on the land of Egypt. It was the worst storm in the land of Egypt since it had become a nation." Reports of hail disasters have become more common. Insurance claims for hail damage have doubled every two years. The storms have devastating results for farms and destroy crops. Some attribute the increase in these events to global warming.

In the Bible, God is said to have sent swarms of flies upon the Egyptians. Nowadays swarms of mosquitoes still descend upon us. The females inject the malaria parasite, plasmodium, which reproduces rapidly in the blood. Recurring bouts of fever weaken the victims until they die. The danger of dying of malaria is particularly high in eastern Africa. At the Kenya Research Institute scientists are trying to establish what it is exactly that attracts mosquitoes.

The bible called them plagues, but we call them natural disasters. They are actually one of the same. And the biblical plagues are coming back. The first episode examines the first biblical plague of Egypt, the Nile waters turning into blood, and how the plague has returned in the form of toxic algal blooms. Each episode of this series analyses the individual biblical plague from a historical and theological perspective, and explains the connection to modern natural events.

In the last hundred years, heatwaves have caused more deaths in Australia than any other natural hazard. This program shows how you can minimise the harmful effects of heatwave by providing practical advice about what to wear, eat and drink and where to go if affected. The program also explains how to keep your environment as cool as possible and the steps you should take if someone is suffering from heat-related illness.

Cyclones are a fact of life throughout tropical Australia. They are multi-hazard, bringing extreme winds, floods, violent seas and storm surges. This program shows how to prepare your family and property, how to access information and warnings as the cyclone is nearing your area and what to do once the cyclone has arrived.

Floods are the most predictable of our natural hazards and can occur far from rivers and creeks. For some types of floods, you may have a relatively long warning period and therefore time to prepare. However, flash floods can occur anywhere and with very little warning. This program explains where you should go for information about the possibility of your property being flooded, what to do when floodwaters approach and once they have receded. It also shows how the design of buildings and fences and the location of access roads can reduce the impact of flooding.

Severe storms can occur with very little warning and with dangerous winds, damaging hail, flooding rains and lightning. They may be short-lived but can leave a path of destruction and can kill. This program shows what you can do to reduce the possibly devastating effects of this natural hazard on your family and property.

Bushfire is a natural part of our bushland environment but can have a devastating effect on people's lives. This program shows how to assess your property's vulnerability to bushfires and how to prepare before the bushfire season. It also explains measures you can take if a fire is approaching, how you should react if caught in a bushfire and what to do once the fire has passed.
