Melbourne to Thredbo M3 LR

[DAVIDL Vic Au]

I’m planning a ski trip to Thredbo (Australia) from Melbourne via Khancoban in my M3 LR. Has anyone done this trip and if so were there any issues with charging? The Tesla app says I should be able to do it with a single supercharger session in Wodonga and 18% left at the end. There seems to be no significant charging options after leaving the Albury-Wodonga area. Thanks
