@mister.hyde It will be a great advantage if you can increase your points, like what you've mentioned na i-Superior ang PTE exam. Yung ibang state rin po kasi, aside from the overall points, they also prioritize applicants with Superior English. I cannot see your points breakdown, pero if possible, you may also consider claiming additional points for Partner Skills (English exam & Skills assessment required for Partner) or NAATI Certification (Translation/Interpretation test in Australia).
To answer your question po concerning visa 489, personally, I think taking this path will give you a better chance of getting invited since ito rin po ang meron kayong pinaka mataas na points. You can check the Australian job sites (ex https://www.seek.com.au/) and filter the search results based on the regional areas you prefer so you can see the opportunities are available for you. For PR visa (189 & 190) options po, previously 75pts and above gets invited. Recently 80pts and above na. I am not certain yet kung ano na pong magiging trend in the coming financial year (July 2019), pero hoping na tumaas na uli ang invitations. God bless on your application 🙂
