Off the beaten track?? Lol, that's just around the corner from me and in a highly populated industrial area. My son actually works for a company in that same street, I believe a few doors down. Strangely enough, I've never been there but my mate bought his mavic from them and they had to send it to DJI in Melbourne for camera issues. Turns out it was a software glitch and Rise Above actually reloaded software and he got it back today.If you're going to be in Sydney there's a company in the south west called Rise Above. They do repairs but I'm not sure how long they will take and if they have the parts needed (I know they're pretty well stocked) to do the repairs. They're a bit off the beaten track in a suburb called Smeaton Grange near Campbelltown. You'll need a car or taxi to get there. Buy Commercial DJI Drones in Australia - Rise Above
