Try hitting your local RTA for some compo too.
that would only work in a very limited number of cases.
1st, it would only work if the damage was casued by bad road maintenence.
and or a pot hole etc.
2nd, you would have to prove that the council / rta knew about the poor road condition, and failed to repair it sufficiently.
in this case, it's clearly not an RTA / Council issue, as some drill bit has fallen off the back of some tradies ute. this is highly unlikely to be malicious. just plain old fashined bad luck.
