hm.. i work for the company that works at the tip, im in the clayton area working on the land fill's there,
for an easy access weigh bridge with parking would have to be Clayton Regional Public tip ... on the corner of Ryans road and Clayton road.
there is a speed hump in there but u can go around it, and there is one at the other end but just a small carpark one should be good,
Guys a bit of a prick there (brown nose) but im sure if your rock up with a decent amount of cars and get someone who is a smooth talker to bargin with him, say $5bucks each car into his pocket im sure he wont give a shit
