Simon travels down the east coast to the magnificent cities of Sydney and Melbourne in the final part of his journey.

First, he visits Surfers Paradise near the city of Gold Coast, the Las Vegas of Australia. Behind the sun and surf, this area has become the country's organised crime capital. Police are cracking down on outlaw motorcycle clubs, accused of being criminal gangs. Simon meets the most notorious and feared biker group in Australia to hear their side of the story.

In the wealthy east coast suburbs, he has a different kind of encounter, joining a vet and his team who rescue and treat injured koalas - thousands of which are killed each year by cars and pet dogs.

Arriving in Sydney, Simon discovers a city of huge cultural diversity closely linked to its booming Asian neighbours, India and China. One in ten Aussies are now of Asian origin. Simon gauges Australia's attitude to immigration and meets the country's first Muslim ladies Aussie rules football team.

On the very last stretch of the journey, he takes to the air to witness the devastating and deadly bush fires ripping through the country, before reaching his final destination, Melbourne, just in time to celebrate Australia Day. Show less
