## 根因

澳大利亚 ETA（601 子类）允许美国公民每次最多停留 90 天；过桥签证（BVA/BVB）仅在实质性签证申请在到期前提交时才适用，逾期停留即使 1 天也会触发《移民法》第 48 条规定的 3 年禁止入境，不会因去新西兰旅行而重置

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| ETA subclass 601 (2024 edition) | active | — | — |
| Migration Act 1958 s.48 | active | — | — |
| ImmiAccount v2.5.0 | active | — | — |

## 解决方案

1. ```
   Before ETA expiry, lodge a valid onshore visa application (e.g., Visitor Visa subclass 600) via ImmiAccount to get a bridging visa A, allowing legal stay while the application is processed. Use the ImmiAccount portal: https://online.immi.gov.au
   ```
2. ```
   If already overstayed, leave Australia immediately via airport with a voluntary departure arrangement (no re-entry ban if within 28 days of overstay) and wait 90 days outside before reapplying for ETA. Contact the Department via Global Service Centre at +61 2 6196 0196
   ```
3. ```
   For stays over 90 days, apply for a Visitor Visa (subclass 600) from outside Australia before travel, which allows up to 12 months per visit with no 90-day limit
   ```

## 无效尝试

- **** — Australian Border Force uses a rolling 12-month calculation: any time spent in Australia in the prior 12 months counts; leaving and returning doesn't reset the clock unless 90 days have passed since the last departure (95% 失败率)
- **** — Bridging visas require a valid substantive visa application (e.g., a work visa) to have been lodged BEFORE the ETA expires; after expiry, you're unlawful and must leave immediately or face exclusion (98% 失败率)
- **** — ETA is non-extendable under any circumstances; the Australian Department of Home Affairs explicitly states ETAs cannot be extended, and any overstay must be resolved by departure with potential re-entry ban (100% 失败率)
