Not at UNSW, It will be good enough to get into UTS if you are eligible for 10 bonus points but they dont have aerospace. If you get 70 your best bet is to transfer after first year
minimum for UNSW aerospace is 91 and u might be able to get 10 bonus points max. I think UNSW might only have a bonus 5. Conditional offers for engineering still require an 80 which is a lot higher than 70 :'(
