Whether travelling in a station wagon or a big RV the rest stops along Australia's highways are a great way to get free overnight accommodation and on the next day move on fast to the next destination. Not all of them have toilets, such as this one in miles. Mobile internet reception can be a huge challenge. Many rest spots are near remote town however. Miles has worked extremely well for me. I always look at the bars on my phone and combine it with a speed test. I have seen anything from 1 MBPS to 100 MBPS and it often varies dramatically with the time of the day. Consider buying a booster or possible satellite based technology.
