I studied IT back in 2015. Career wise, yes it is rewarding but the journey to PR is quite expensive unless IT ka na talaga before.
I have to do the professional year program to get a positive assessment from ACS which costs 12k aud plus yung seminars for CPD points
If gusto mo maging PR through SV, I would suggest take healthcare courses like nursing. Mataas demand dito talaga, not sure if it's a rewarding career but would probably say it's fulfilling as you help people in the community. (assumption ko lang)
