Nice grass strip. Parking at the south end in a circular area on basically their lawn. Just push your aircraft back to make room for others coming or going. We landed south and took off south. Be configured and on speed before getting to 90 degree bend in river on short final. On departure to the south, there are two other nearby strips and slightly lowering terrain. Others were taking off to the north, but that doesnt seem to leave you many options. Watch for sprinklers on the edge of runway.
Update 2015: Mackay Bar is no longer open to drop-in traffic. Get permission before landing.
