Goodness me

Mr Arouet
Just let me get this right.
Yes, best you get this right
Class E airspace at Broome and Karratha is different to this? Because? (no radar perhaps)?
No. As has been pointed out, the CASA have determined [how exactly is anyone’s guess] that the class E below A045 [as per peuce's diagram] will include a mandatory VFR broadcast area [prior to entry, and during]

Issues here:-

1. It makes the tower E not E, and not D, but a no-mans land
2. It gives ATC a duty of care [known VFR traffic] without the tools [Class D] to fix it re: IFR and other VFR.
3. If ATC cannot fix it, your [Alice in WL] C182 in MB airspace [it is ML centre BTW] scenario comes in to play sort of. The difference:-

a) At YBRM or YPKA, the IFR C182 is subject to a clearance [not a FIS as in Oz G - ICAO F]
b) The VFR is not on radar [or ADB-B], but is talking [known]
c) ATC cannot provide 'separation' [or safe segregation] because the VFR can do what they like [as far as track and altitude is concerned]
d) The end result is IFR and VFR talking to each other [on the Class D tower frequency] at the same time the ATC is trying to operate a service [where is Mr Smith on this frequency/chatter loading the tower ATC issue???? sold the farm for anything labelled E is my bet ]
e) The conflicting IFR [in this case the C182, although it could be Bloggs in his kero-burning aluminium missile] is going to level off until he can be sure he has missed the VFR, in the meantime, trying to talk with the VFR to make sure he/she is not going to do anything unexpected, and at the same time fecking up ATC sep with other IFR that were 'going to be' separated before Bloggs rightly levelled off [and missed his vertical separation requirement] until he knew the miss with the VFR was guaranteed.

And, before you crap on about IFR Air Carrier being 'nancy boys and girls', what do you suppose they have to do [insurance/duty-of-care etc] with known traffic threats? Bloggs has the ability to do something [play verts], ATC does not! Do you get the basic concept?
Class E airspace is "controlled airspace"??? but ATC don't talk to everybody flying there even if they can see them like in class G???
No, there are no ‘clearances’ in G [very difference liabilities for ATC]
RA-Aus are not allowed into any "controlled airspace"???
Which includes E! or does it?
In class G airspace it is OK for IFR traffic to be worked with radar backup?
Worked, Radar Back-up, Frank you have NO idea of the ramifications [legal quagmire] that sits with ATC in different classes of airspace [with different sovereign legislation in each country]. Do not insult Australian ATC’s and Pilots by presuming you know better, your diatribes here prove you do not!
Is class G airspace "controlled then by definition?
See previous
If so, by deduction the problem must be ornithopters, gliders, GA Charter, flying training, balloons, kites and UAV's. Oh, and whale watching gay people who's motives become a concern for our backseat vocal busdriver in the big scheme off things and.... land rights in class E and G airspace which should all be "controlled".
A stellar example of your professional, intelligent, and worldly view of the subject matter you regularly display.

Might I politely [in the nicest possible way] recommend you stick to Bundy Rum and Flight Sim designed for the ‘Colts’ of old regret?!
