The carpark in the middle of Anzac Pde opposite the church will probably provide most opportunity. If full, please try Sturt St and surrounding streets as. Disabled drop off available just outside main entry to church.
There are bus stops close to HTK either side of Anzac Pde so checking out https://transportnsw.info. HTK is also a 2 minute walk south of the ‘ Juniors Kingsford’ light rail stop.
