I know this is Filipino blog but you are limiting the responses.
Alternative to IELTS (Academic or General - depends on the skills assessment requirements) is PTE (Academic only)
Vetassess Requires 1 year in the last 5 years for skills assessment. FULL time work, paid experience. English is not required for this stage(Vetassess)
Points needed are dependent on the occupation and visa class.
Points at time of issue and visa submission must remain the same - cannot be less.
