These are all well and good for short term or once in a while resupply. For a long term solution , I'd 1) build the air bridge from Alice Spring to one of the smaller bases (which can also be used for fast deployment of short range fighters). 2) build up each of the bases on the west coast from Perth all the way to Darwin to at least level 2. You can provide CAP for any convoy going to or from Darwin , as well as having a base to deploy strike aircraft if needed. I'd especially build up Exmouth gulf , both because it was done historically (great place for subs based in Perth to top up their fuel levels before heading to the DEI. IF you can hold Darwin , you can base Maritime patrol aircraft there , as well as long range bombers to be an absolute pain to your enemy in the DEI. Ideally you should try and hold the islands north of Darwin , but at the very least deny them to your enemy. If he holds them , he can sweep Darwin with zero's. If Darwin is to be any use to you , you need to shut down those airfields.
Also , if you build up those bases , it gives you the option of launching raids and invasions into the DEI. That will force him to keep large amounts of troops tied up that he could dearly use elsewhere. Two more points. Katherine is an excellent base to build up and put heavies. You can reach the islands , yet to hit you he has to go through the fighters you have CAPing Darwin. You might consider keeping a Division of infantry there. Bring them overland from Alice springs (take the railroad there , then walk). By keeping them at Katherine, they are out of sight of RECON planes checking out Darwin , and they can be moved up relatively if he tries to land.
Darwin is like the Aleutian islands. While it has potential , it's a pain to keep , but you must garrison it to keep it out of your opponent's hands. It's not a war winner for either side , but it's nuisance if the other side has it.
