Cheap Flights from Dublin to Perth

The expensive stretch runs from mid-December through January, when Christmas and New Year travel overlaps with the southern summer in Australia and demand out of Dublin pushes fares up.

Fares ease through the shoulder months, and February is the cheapest month, landing in Perth's warm late summer. A midweek departure out of Dublin often undercuts a weekend one, and prices are published for every month from September through August, so compare the full calendar before you settle.

What separates these fares is mostly the stop, not the seat: every carrier here is a full-service network airline, so the choice that matters is where you change. Emirates and Etihad route via Dubai and Abu Dhabi, Thai Airways via Bangkok, Malaysia Airlines via Kuala Lumpur, Cathay Pacific via Hong Kong, Vietnam Airlines via Hanoi or Ho Chi Minh City, and Turkish Airlines via Istanbul.

British Airways and Qantas work through London, while Lufthansa City Airlines feeds the German network and can add a second change before Perth. Bags and meals are normally part of a long-haul full-service fare, but confirm what your booking class covers.

Sort out your Australian entry papers before you fly: border control in Perth will want your visa or electronic travel authority ready, and biosecurity screening of food, plant material and outdoor gear is strict enough that undeclared items can draw fines.

Perth Airport sits a short drive east of the city centre, with taxis, rideshares and airport buses covering the run into town. If you continue to another Australian city, domestic departures can use terminals away from the international one, so check your onward terminal and leave slack between flights.

Country facts: Wikidata

• Check which visa or electronic travel authority your Irish passport needs for Australia, and have it approved before you pay for tickets.
• Keep your passport valid well beyond your return date, since airlines can deny boarding over expiry rules.
• Look at the connection length and whether one ticket covers every leg, because two separate bookings leave you exposed if the first flight slips.
• Compare baggage allowances across each leg, as the short-haul start of your journey may include less than the long-haul carrier into Perth.
• Weigh the calendar against your dates: February prices lowest, while December and January cost more.
