The School of Electrical and Information Engineering (Building J03) at the University of Sydney is Building J03, a 5 minute walk from Redfern railway station. I am in room 852 (8th floor) and other contact details are available here.
The Shepherd St Parking Station on the corner of Shepherd St and Cleveland St (entry on Shepherd St) is the most convenient. Street spots between Shepherd St and Abercromie St are also available.
From the airport
A taxi ride from the airport is approximately A$30. It may help to tell the driver that the School is located on the Darlington campus which is accessed by turning into Butlin Ave from City Rd.
From the airport, the easiest route is to take the City Rail Airport link to Central (A$11.60 one way). From there, change trains to Redfern.
