You can, but I'd think that one of the ham radio groups would be a
better choice, as anything you find that meets your specifications is
likely to be on the ham band.
Without using ham band equipment, your best bet might be a cell phone
with a modem of some sort.
That 5+ km requirement is the problem -- you can find 900, 2400 and
5800 MHz radio gear that will give you the desired data rate, but
their ranges are likely to be less than one km due to the very limited
(I'm assuming that the situation is the same over in Australia as it
is here in the US. I don't know for sure.)
And then there's the issue of a UAV. Over here in the US, the FAA
generally leaves us modelers alone, as our planes are always under
direct control and in visual range. But UAVs operate under different,
far more restrictive rules, and while the line between the two is
rather vague, it's generally less about size and more about how the
plane is controlled and how far away it can operate. If your plane
was 5 km away, I seriously doubt the FAA would consider it to be a
normal model airplane anymore.
Maybe things are signifigantly different down under. But I doubt it.
