Hi Nancy!
Wow, it's been a long time i've last logged in here. Luckily i could remember the password to login.
Well, I have no idea of the post of mine that you've gone through. Anyway I didn't try either NT or the job offer option after all. It was so complicated. But I was lucky in another way. In 2013 November I got the Orana state sponsorship and I applied for 489 regional visa. I got it in 2014 February and in the same month i moved to Dubbo with my family. Dubbo is a really really nice place to live in. Specially to raise a family. Almost all the facilities are there along with very good schools and the neighbourhood is awesome. I lived there for two years and applied for 887 PR visa and moved to Lithgow, another regional area, close to Sydney so as to visit my customers in Sydney time to time. Last month I got my PR. Hoping to move to Sydney in a couple of months. Everything went smoothly during the past 2 1/2 years. Life is so easy in regional areas, of course you need to have some kind of job. It depends. I'm a self-employer, so I didn't have any problem in jobs.
I think obtaining a job offer is not that easy. That's why I gave it up and went through this process. If you are sure on a job offer then it might be worth trying on it, otherwise trying at least the regional option is so much the better, if you are unable in 190 visa.
Sorry, I couldn't give a straight forward answer to you question. I again suggest you, if you are eligible, apply for any 489 regional visa and reduce the time to be a PR holder in Australia.
Cheers
