Deciding between NUS/NTU CS and USyd CS as an international student — need advice on competitiveness, job prospects, and Tuition Grant

Hi everyone, I'm currently trying to make one of the biggest decisions of my life and would really appreciate some honest input from people who've been through it.

For context, I recently graduated from an international school in Singapore. I applied to NUS and NTU for CS, and my counsellor says I have a high chance of getting in (no offers yet). I've also applied to the University of Sydney for CS — I'm almost guaranteed entry there and have been offered a 20% scholarship off tuition.

I don't have any competitive programming or olympiad records. I'm a decent student but definitely not top of my cohort. Here's what I'm trying to figure out:

1. How competitive/cutthroat are CS classes at NUS/NTU really?

I keep hearing about bell curve wars and people being extremely competitive. Is it really that bad if you're not a "star" student? Are there people who are just average but still do fine and enjoy the experience? Or will I be constantly crushed by people with IOI medals?

2. Job hunting as an international student in Singapore vs Australia

How hard is it to actually land a job or an internship in SG as an international after graduating? I know MNCs and banks hire here, but do they really hire internationals fresh out of NUS/NTU, or do Singapore citizens/PRs always get priority? Compared to graduating from USyd and job hunting in Australia, is one significantly harder than the other for non-locals?

3. Is Tuition Grant Worth It?

I know NUS/NTU international students can apply for the MOE Tuition Grant, which comes with a 3-year bond to work in Singapore after graduating. Has anyone gone through this? Is the bond actually a problem in practice, or is it fine since you'd probably want to work in SG anyway? And does it really make NUS/NTU comparable in cost to USyd after the 20% scholarship?

I know NUS/NTU's global rankings are strong, but I'm trying to be realistic about whether I'd actually thrive there vs. having a more comfortable experience in Sydney. Any honest takes especially from international students or people who've worked in SG's tech scene, would mean a lot. Thanks in advance 🙏
