Cons:
It's harder to find job in Adelaide. A lot of SA locals/migrants transfer to bigger states just to find a job.
If sanay ka sa Big city lifestyle ng Sydney, then you will find Adelaide really boring.
Pros:
In my opinion, Adelaide has a more pleasant environment than Sydney. Less gulo, less crimes, more peaceful and I feel more secured to live in Adelaide with my family.
Real estate price is way cheaper than Sydney.
Most locals who transfer from other state to Adelaide/ South Australia are retired/elderlies.
