For longer term car parking there are two close, convenient options:
Firstly, Tournament Parking just across the road on Nelson Street, $8 all weekend, but do note that they are closed 10pm-6am.
Secondly, Wilson Parking on Victoria Street offer 24 hour access for $6 per 12 hours.

There are five minute loading zone carparks directly outside the venue for convenient drop-off and pick-up of your equipment. Please use these sparingly and note that it is a strictly enforced tow-away area.
