Benji and Joel Madden are on a Sydney party bender to rival anything in Hollywood.

The pair started off with the launch of the Blackberry Curve just hours after they landed in Australia.

The tattooed twins from Good Charlotte arrived by boat at Simmer On The Bay in Sydney’s Dawes Point. Joel, who is travelling without his partner Nicole Richie and their two children, wore sunglasses and leather while Benji wore his signature fedora. The pair DJ’d for a reported substantial appearance fee.

They were later seen at hot Kings Cross nightspot theclub. According to witnesses, they stuck to Red Bull and cigarettes before leaving at about 2am. The late nighter did not stop them arriving five minutes early for a 7.30am radio interview the next day, likely the result of the time zone swap.

The next night they moved on to the State Theatre for Absolut Vodka’s Rock edition party, where they kept the company of local bright young things.
