Pretty sure 'The Farm' is not happening.
Even more reason they (Maca Castle) would be keen to attract some additional visitors to their shop/cafe even if they don't go in to the park itself? They also have space out the front.Yes the Maca Castle is a bit off the beaten track since the highway upgrade, about a 5km detour via Tamarind Drive & Hinterland Way. Still possible I guess but it’s definitely not easy to get to like it once was.
Last I heard was that 'The Farm' is for sale. Perhaps that could halt or stall supercharger options? Seems like a logical spot for it though. I saw in the local paper up here this week that the Byron on Byron resort now has 2 tesla chargers too.
