The easiest way to get to the Australian Technology Park is by train.
Redfern station is serviced by trains from the city and North Sydney every few minutes.
The main entry to the ATP is Garden Street - see below. There is a fair bit of construction happening at the present moment, and whilst there is ample parking at the ATP, you may have to negotiate barricades to various temporary parking areas.
