Any migrant arriving here should be able to support themselves for at least a few months - plenty of documentation and checklists that make this requirement clear. If you arrive here knowing the deal but without the means to support yourself, I really don't think it's fair for the state to be expected to stump up cash.
Getting a positive skills assessment but then not being recognised 'on the ground' is common in various professions and a quick Google search gives easily enough examples and experiences to raise that as a potential issue.
I'm a regular contributor to this board and have been for years; I don't post on here only because I need the answer to something. I do try to give information if I have it to those who ask for it. Not liking the information because it's not what you want to hear is a risk you run when you ask a question on an open forum like this.
On a practical note, if the English in your cover letters and CV is similar to your usage of words on here, you really need to ask someone to tweak it or you'll be at a disadvantage regardless of your skills and experience.
