The Diplomat, the political thriller starring Keri Russell and Rufus Sewell, streams in Australia only on Netflix. All four seasons are there, including season 4, which arrived with all eight episodes on 15 October 2026, and it is included in every Netflix plan from $9.99 a month (Standard with ads). Netflix renewed it for a fifth season at the end of October. If you searched for The Diplomat and found a show set in Barcelona, that is a different series: the British drama with Sophie Rundle, which is on Stan.

The rest of this guide is about the Netflix series, which is the one most Australians are searching for after season 4.

The Diplomat seasons and release dates

Every season is a Netflix original, so each one lands on Netflix in Australia on the same day as everywhere else, with all episodes at once.

Season	Episodes	Released on Netflix
Season 1	8	20 April 2023
Season 2	6	31 October 2024
Season 3	8	16 October 2025
Season 4	8	15 October 2026
Season 5	To be announced	Renewed in late October 2026, no date yet

That is about 30 hours of television, each episode running close to an hour. There is no free way to watch it in Australia: it is not on a free-to-air catch-up service, it is not sold on Apple TV or Prime Video, and Netflix has no free trial in Australia.

How much it costs to watch The Diplomat in Australia

Every Netflix plan includes all four seasons, so the cheapest is enough.

Standard with ads ($9.99 a month) carries the whole series, in Full HD, with ad breaks. Standard ($20.99) removes the ads and adds a second screen, and Premium ($28.99) adds 4K and four screens. If you only want to catch up on The Diplomat, one month of Standard with ads is enough time to watch every season; there is no lock-in contract, so you can cancel when you finish.

What happens in season 4 (no spoilers)

Season 4 keeps Kate Wyler at the centre of the crisis between London and Washington, with her husband Hal, now the US vice president, and Allison Janney's President Grace Penn pulling her in different directions. The season builds to a G7 summit. Creator Debora Cahn has said she has a plan for where these characters end up but not a fixed number of seasons.

Netflix reported 4.8 million views for season 4 in its first week, rising to 5.5 million in the second, when it was the third most watched English-language show on the service. Two weeks after the premiere, Netflix renewed the series for a fifth season. No release date, plot or new cast has been announced. Going by the gaps between seasons so far (12 to 18 months), late 2027 is the earliest realistic window, but that is our estimate, not Netflix's.

Is The Diplomat on Stan, BINGE or Prime Video?

No. The Keri Russell series is a Netflix original and is not on Stan, BINGE, Prime Video, Disney+, Foxtel or any free service in Australia, and it is not for sale on digital stores. The Diplomat that is on Stan is the British series with Sophie Rundle, a crime drama set around the British consulate in Barcelona. It is a single six-episode season and is included in every Stan plan.
