Irish Passport to Australia

Yes — Irish citizens need an ETA (Electronic Travel Authority, subclass 601). AUD $20 application fee (~€12), valid 12 months, allows multiple visits up to 3 months each. ETA is a digital visa linked to your passport. Apply via the official Australian ETA app (iPhone + Android), via etas.immi.gov.au, or via a travel agent.

3 months per entry. ETA is valid for 12 months from approval, allows unlimited entries within that period, each up to 3 months. Cannot extend a 3-month stay — you must leave + re-enter. For longer stays, apply for a different visa: visitor visa (subclass 600, up to 12 months), working holiday (subclass 417), or work + skill-based visas.

Best method: the OFFICIAL Australian ETA app — free download (iOS + Android), pay AUD $20 inside the app, scan passport with phone camera, take selfie, approved typically within 12 minutes. Alternative: etas.immi.gov.au website. Avoid third-party agents charging $40-$80 for the same service. The app is the cheapest and fastest.

Yes — Ireland has a Working Holiday Maker reciprocal agreement with Australia (subclass 417). Up to 12 months in Australia with right to work + study. Apply at immi.homeaffairs.gov.au. Cost AUD $670. Age 18-35. Two extensions possible (regional work). Different from the ETA — Working Holiday allows employment, ETA does not.

Depends on duration + destination. Same-day connections within 8 hours, staying airside (not collecting bags, not leaving sterile area): generally no ETA needed but check airline rules. Overnight or longer connections OR if you need to collect baggage: ETA required. Same applies for Aer Lingus / Qantas connections in Singapore + Hong Kong en route to Australia.
