Can I change from TAFE, Adelaide to TAFE, Sydney after 6 months of Diploma to complete next Diploma of 6 months?

Hi, It can be possible after completing 6 months, usually there are restrictions before completion of 6 months. But, having said this you have to check with the current TAFE you are enrolled with. You will also require the offer letter from the new TAFE. Check with the schools directly.
