Handsomedan:
Our house is adjacent to council-owned reserve land which has regenerating bush on it. We reported some very large noxious plants to the council. They said they'll get their contractors to come out and cut them down (they were large trees of the noxious kind).
Long story short: contractor arrived, said "Sorry mate, we only do the other side of the street - you'll need to contact council and get the other contractors out". 3 months (and many emails/phone calls) later a new contractor finally turned up and the offending trees were removed. 3 MONTHS!
Both sets of contractors also agreed it was ridiculous.
We have a similar situation - we back on to a small patch of council bush that pretty much no-one else has access to. I called them a few years ago saying there were a bunch of big Taiwanese cherry trees growing there, and could they please remove them.
They apologized saying that they didn't have the budget.
I then asked if I could cut them down, and they were very happy for me to do so. I got a decent bit of exercise, and 2 year's worth of good firewood out of that project.
