World’s best city for nightlife

By Maureen O'Hare, Aug 25: Sun, sea and samba: Rio de Janeiro in Brazil has been declared the best place in the world to party right now, according to Time Out’s new survey of thousands of people worldwide. Its live music, dance halls and bohemian bars have ravers raving.

Rio ranked high on affordability, but the place that’s hardest on the partying but easy on the wallet is Manila, the capital of the Philippines. The late-night food markets are particularly worth a visit, say the nightlife experts.

The best place to party in Europe, unsurprisingly, is Germany’s legendary clubbing capital Berlin. Outdoor raves have made a comeback, says Time Out, and the grande dame of decadence, Berghain, has a new sound system.

Please don’t

You can fight for your right to party, but here are a bunch of things that destinations around the world would like people to please stop doing:

• Melbourne has had enough of your silly little wheelie nuisances. So it’s banned electric scooter rentals.

• Airports have never been cool with blades, but last week, a missing pair of scissors shut down one of Japan’s busiest hubs. Be careful with your tools, guys.

• Some US bars and eateries are banning 20-somethings. Get out of here with your fresh skin and your untarnished hopes and dreams.

Their love story captured the world. Sphen, one-half of Sydney’s famous gay penguin couple, has passed away at the age of 11. His partner, Magic, started singing to express his grief – and the whole colony joined in.
