Pubs and Bars:
Perth CBD and nearby Northbridge has many bars and nightclubs. Bars usually become crowded after 5PM with those who have just finished a hard day's work.
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).
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.
