Yeah, I'm not surprised you cannot drive like this. Australia is different to your country though, loads of wide open spaces and so driving at high speed for hours on end is not unusual. 95% of the population lives on only 5% of the land and in between towns and cities is a lot of open road, thousands of kilometres of it.
Yep, those houseboats are great fun. There's some amazing places along the river too, some best seen from the river itself. They are very relaxing holidays generally and so much fun.
Thanks for commenting, it's appreciated.

Damn. That's under the speed limit on the Freeway! 75 mph (120 kph) and some people occasionally cheat on that...
That road is a minor road and at more than 110kph one would be taking risks. Of course, 110 is the State limit here so it is what it is. In the Northern Territory there's a few highways that are 130kph (81Mph) but typically the limit is 110 all over.
