I have a brand new Torklift Eco hitch here just north of Brisbane (Bribie Island). I got it even before my model 3 arrived in 2019, but have never got around to putting it on the car, so after 3 years must not need it. It is complete including a 50 mm tow ball and wiring. I think the whole setup is worth over $2K new today, so asking around $1500 + freight if you can't pick up locally. Negotiable on price, and willing to package it up for freight anywhere in Oz if you organise the freight.
