Joshua Anthony Frydenberg (/ˈfraɪdənˌbɜːrɡ/) (born 17 July 1971) is an Australian former politician who served as the treasurer of Australia and deputy leader of the Liberal Party from 2018 to 2022.

At the 2022 federal election, Frydenberg suffered a significant swing against him, and lost his seat to the teal independent candidate Monique Ryan.

His mother was a Jewish Hungarian born in 1943 who arrived in Australia in 1950 as a stateless child from a refugee camp after escaping the Holocaust.

[3] His great aunt, Mary Frydenberg, is also a victim of the Holocaust; she spent 2 years at the infamous Auschwitz concentration camp.

Frydenberg played against Mark Philippoussis and Pat Rafter, and represented Australia at two World University Games.

He opted to accept the latter, completing a Master of International Relations at University College, Oxford, with a thesis on Indonesian politics.

[7] Frydenberg was one of seven Liberal MPs in the 46th Parliament of Australia who obtained degrees at an Oxbridge or Ivy League university, the others being Alan Tudge, Angus Taylor, Andrew Laming, Dave Sharma, Greg Hunt and Paul Fletcher.

From 2003 to 2005 he was a policy adviser to Prime Minister John Howard, specialising in domestic security issues, border protection, justice and industrial relations.

In the days leading to the preselection convention, Queensland frontbenchers Ian Macfarlane, Peter Dutton and Santo Santoro backed Frydenberg's credentials, for which they were criticised by former Victorian Premier Jeff Kennett.

"[11] After Georgiou announced his decision to retire at the 2010 election, Frydenberg won the preselection vote, defeating industrial lawyer John Pesutto, who later went on to become the leader of the Victorian Liberal Party.

[12] Frydenberg's candidacy was supported by references from former Prime Minister John Howard and former Opposition Leader Andrew Peacock.

He enunciated his belief in small government, called for stronger ties with Asia while also maintaining a solid alliance with the US and proposed a target of having two Australian universities within the world's top ten by 2030.

On 23 December 2014, Frydenberg was sworn in as Assistant Treasurer in a ministerial reshuffle and replaced Arthur Sinodinos, who resigned due to delays in an ICAC inquiry.

Ed Husic said that he felt uncomfortable with his party questioning the legal citizenship of stateless Jewish refugees escaping Europe.

In July 2022, the Federal Court approved a settlement in which Staindl would make no further statement disparaging Frydenberg or his lawyers and no further payment would be required.

[32] At the 2019 federal election, he retained his seat of Kooyong with a reduced majority, following a challenge from high-profile Greens candidate Julian Burnside.

[33] Perceiving Burnside as a strong contender, the Liberal Party doubled its spending on the campaign in Kooyong, from $500,000 to $1 million.

[41][42] Frydenberg's loss would mark the first time that the seat of Kooyong would not be held by the Liberal Party or its predecessors since its inception in 1901.

[44] In July 2022, Frydenberg joined investment bank Goldman Sachs as a senior regional advisor for the Asia Pacific.
