🧭 In Summary因为 NSW / SA 的 190 是“工作导向型州担保”，而幼教的“合法工作前提”是 ECT 教资。不是你“不能申请”，而是你走不到申请那一步。我们拆成 4 层来看。

Layer 1: State Nomination ≠ Assessment Only

Many applicants confuse the following visas:

• Subclass 189 – Independent Skilled Migration → based on skills assessment + points only
• Subclass 190 / 491 – State nomination → based on skills assessment + relevant employment in the state

Your question relates to Subclass 190. In NSW and SA, the practical requirements for Early Childhood Education (ECE) under 190 are:

A valid ECT skills assessment
Relevant employment in the nominating state
In most cases, employment specifically as an ECT ECT 职位

👉 In practice, without an ECT job, the foundation for state nomination does not exist.

Layer 2: The Real Issue with GD Is Not Skills Assessment, but Teacher Registration

A common response is:“But a Graduate Diploma (GD) can still pass an ECT skills assessment, right?”Correct.A GD can still obtain an ECT skills assessment through Australian Children’s Education and Care Quality Authority (ACECQA). This part has not changed.❌ The real bottleneck is Teacher Registration.In NSW, to legally work as an ECT, you must be registered with NSW Education Standards Authority (NESA) as an Early Childhood Teacher.Current reality: Graduates with a Graduate Diploma in Early Childhood Education generally cannot obtain ECT teacher registration.Once this step is blocked, everything downstream collapses.

Layer 3: No Registration = No Legal ECT Employment

This is the most commonly misunderstood but most critical point.Even if you have:

 ✅ An ACECQA ECT skills assessment
 ✅ A GD qualification
 ✅ A valid visa

Without state teacher registration, you:

你就：

• ❌ Cannot be legally employed as an ECT
• ❌ Cannot accumulate recognised ECT work experience
• ❌ Will be rejected by major childcare providers

Including national employers such as Goodstart Early Learning,

where teacher registration is a non-negotiable requirement.So the real-world outcome becomes:GD → no teacher registration → no ECT job

Layer 4: State Nomination Is Employment-Driven, Not Qualification-Driven

When we connect the full chain, the issue becomes clear:

GD completed
→ ACECQA skills assessment (✔ still possible)
→ NSW / SA teacher registration (✘ blocked)
→ Legal ECT employment (✘ impossible)
→ Meeting state nomination employment criteria (✘ not met)
→ Subclass 190 (✘ path breaks)

👉 Therefore:❌ It is NOT that “GD holders cannot apply for 190”✅ It is that GD holders in NSW / SA cannot meet the core prerequisite: ECT employmentThis is a structural issue, not an operational one.

Why Is a Master’s Degree Now Considered Essential?Because a Master of Teaching (Early Childhood) enables what a GD no longer can:

 ✅ Eligibility for ECT teacher registration
 ✅ Legal employment as an ECT
 ✅ Accumulation of state-recognised work experience
 ✅ Re-entry into the Subclass 190 pathway

As a result, the mainstream pathway has shifted to:GD → pathway Master (usually 1 year) → Teacher registration → ECT employment → State nomination，This is not an “agent-driven upsell”, but a consequence of:Policy settings + teacher registration rules + employer requirements changing together

A Very Practical Conclusion

If your target is Early Childhood state nomination in NSW or SA:

 A GD alone no longer constitutes a complete migration pathway
 A Master’s degree has effectively become the entry ticket
 The bottleneck is not the Department of Home Affairs, but the teacher registration system
