Radio National is very audible on the TWR SDR Radio located in Southern Africa on 5010 about that time of 1700 hours UTC. However, even using that SDR from less than 1000-2000 km away you can often hear AIR underneath the transmission. There is quite a bit of AIR frequency activity on 60 meters around 4800 khz, 4810 and other places up and down the band. The same goes for China Tibet Broadcasting Service on 4905 khz about 1700 UTC and 4920 in parallel as well as 6200 all of which might be copied in New South Wales and the rest of the Australian continent and most of SE Asia.
