clubs
Perth has a small but strong dance music scene which revolves heavily around drum & bass. Club nights and international gigs are held at a variety of venues across the city centre, Northbridge and outer suburbs check out local street press magazines such as Xpress for gig guides and further info for a comprehensive gig guide).
Almost all clubs in Western Australia have very strict ID policies and it is highly unlikely that you will get in if you do not have your passport or an ID issued in Australia by a government agency either an Australian driver's license or proof of age card with you, even if you definitely look over the legal age. Also most dance music bars/clubs close at 2AM following Friday and Saturday nights and are subjected to Police enforced lockdowns and lockouts as is the case in Brisbane, so you will find yourself stuck in one place after 3AM, and be stranded should you be short on money for a cab.
