didn't realise they had converted their orions to drones The P-3s are being replaced by a mix of P-8s and MQ-4Cs. The exact mix hasn't been finalised as yet, hence the P-8 order being for 8 plus the option of 4 more. |

If you read the article above it quotes the orions are drones....
Yes I know they have put an order in for 8 P8, but on the Aussie aviation site today saw that it was confirmed at 12 but am sure it it is only 8 with hopefully another 4 to follow in a few years.
They havn't decided on drone numbers etc but lots of people have said it would have to be a minimum of 6

You're not supposed to refer to them as drones, they are Unmanned Aerial Vehicles (UAV). The military hates the media calling them drones apparently.
One thing that puzzles me is how do they manage to fly all over the place via remote control without any interference from other radio signals jamming their signals? I have seen r/c models crash when someone else turned on their r/c set on the same frequency, and with all the multitude of radio signals beaming round the world from all sorts of sources how do they prevent this from happening with the UAV's? Do they not use radio signals for controlling them? Is there some other r/c system now?

The command channel for military UAVs is typically encrypted. If the command doesn't have the right codes attached, it is ignored.
Note that often the sensor feed sent by the UAV is NOT encrypted as it slows the process down, requires processing power on the UAV, and you often want people that don't have decryption capability to look at the output (e.g. allies).
More sophisticated UAVs (e.g. Triton) navigate via waypoints etc just like an airliner. Often they send them to say Australia by basically giving them the command 'fly to Darwin, via airspace that we have already told you is available to you'. The resulting plan can of course be modified (either prior to or during flight), but it is mainly automatic in the case of the fancier UAVs.
