Aerocat - You are spot on!
Broome needs a full length taxiway first & foremost. But hey, that Broome real estate is getting damned expensive isn't it! Far, far too much kero has been burnt whilst waiting for strings of lighties to land during some of my visits there. No disrespect intended here, we all have a right to share equally, but a bit of consideration would go a long way in the meantime.
Secondly, the CAGRO needs to remember he is there to provide traffic info, NOT control the said traffic.
Karratha - Bring on the new taxiway too.
I'm not so sure about the tower bit though.
