Cole crossing is part of the Cox Scrub Conservation Park, and is only 1.9ha in area, and has recently become more populary with 4wd and trail bikes.
Obviously no trail bike is going to create a 1.5m deep hole though, this, and other pictures i've seen recently of the border track show the damage that 4wd's can do.
Motorcycles aren't totally innocent, however, so do try and ride only on allowed areas.
