Drones in Australia

Saw a YouTube video the other day posted by a bloke in the US who lost and found his Mavic Mini. He flew it along a river until he lost connection. It initiated auto return home but after a while he realised it wasn't coming. After checking all his data he eventually found that the altitude for return to home had defaulted to 20 metres and at this height it failed to clear the trees in the straight line between where connection had been lost and the controller. A reminder to always survey your surroundings and to check and adjust the RTH altitude setting before you fly. P.S. The mini was recovered but totally destroyed.
