I found what appears to be an abandoned Pajero with boat trailer attached in Drummoyne this week - this is right outside the Drummoyne public school.
They were pretty easy to spot as potentially abandoned - the tyres on both the 4WD and trailer were half flat, and although it is not easy to see in this photo, both are piled high with dirt and leaf litter - they look like they have been sitting here for some time.
You can see the state of the windscreen in the photo below, along with some of the leaves that are piled on the car. The rear number plate was missing, the front number plate was sitting on the dashboard and I couldn't find a registration sticker (although the windows were so filthy, it would have been easy to miss).
Canada Bay Council has an online form for reporting this kind of thing, which I have completed. We'll see how long it takes to get rid of them.
