Visa 190 state nomination approval times (60+5+Job offer)

Hi everyone,

I submitted my ICT BA state nomination on the 16th of October. 18th I got confirmation about this. The 31st of October they phoned to verify the job offer I have in Melbourne. From then up to today nothing else (that I know of) has been confirmed. I know the waiting period is 12 weeks. Is this a estimate time frame or do they only really let you know after 12 weeks? I have 60 + 5 points and I think the Job offer should give me a very good shot for the visa, doesn’t it?
