With a State Nomination you would apply for a subclass 176 visa, where the points pass mark drops to 100.
The key is therefore finding a State or Territory Government that will nominate you for a permanent residency visa. Work your way through each of them, by typing "skilled migration South Australia", "skilled migration Western Australia", etc into
Google
Note that with the changes to skilled migration the wanted skills lists and procedures in some of the States have not yet been finalised.
Best regards.
