State's pre-invite is not same as 190 visa invite. Once a state sends an invite, you may have to pay a nomination evaluation fees. As an example, NSW charges AUD $300 to evaluate your documents and then nominate you for 190 visa. Ore-invite by state does not guarantee a 190 invite. Victoria is notorious to reject high number of pre-invited applications after evaluating the candidate documents. NSW is more reliable and has high percentage of nomination approval if your documentary proof is reliable.
