It can be very dangerous, but is very common and rarely is dangerous. Light small fires, with an area around well-cleared, and avoid doing so during windy weather. Perhaps the most important thing is put it out! Many fires are started by people leaving fires that seem to be out, but smoulder for hours or even days then reignite. Douse with water (if you have enough) and cover with sand, dirt, whatever (but nothing that contains leaves, wood, etc.!) and just be totally sure it's out!

No. There will be long sections without coverage.

Regarding leaving Darwin in September, I would strongly discourage you from riding in the North between October and March as a minimum, unless you are a masochist or used to very hot and humid weather. Even September is very hot and if you're heading into WA, the Kimberly is even hotter than the Top End of NT. Daytime temperatures up to 45 are not uncommon and it will rarely drop below 35 degrees.
Look at this table for typical October weather (September may be cooler, may be the same, depending on the year) - http://www.bom.gov.au/climate/dwo/20171 ... 1710.shtml
Coldest day 34.5, most days around 40. Most importantly, coldest night 22.4, most nights 25 - 27 - it'll be over 30 well past midnight for much of the month, as well as humid and little wind.
Coastal areas will be slightly cooler, and have more wind, but also more humid.
Give serious consideration to how this weather will affect you day after day for weeks on end! I live here and I wouldn't even consider doing it at that time of year. You'll land in the heat and start riding and it'll just get hotter and hotter and more humid for months.
An alternative, if you're landing in Darwin, would be to ride directly south to Adelaide via Alice Springs. As you head south and inland the weather at that time of year is still fairly mild, so you'll be out of the hot weather within a week or two.
Alice can still have hot days at that time of year, but lots of cool ones and, more importantly, the nights cool down - http://www.bom.gov.au/climate/dwo/20171 ... 1710.shtml
This is all said without looking into the prevailing winds, which are fairly predictable and constant, so make sure you look that up as well!
