Career
Acting
Lonsdale's first acting job was at age 16, with a dancing part in the film Razzle Dazzle: A Journey into Dance (2007). The following year, he appeared in an episode of the Australian medical drama series All Saints. He was also a recurring cast member on the Australian teen drama series Dance Academy's second season (2012) in the role of Oliver Lloyd, being added-on as a regular character for the show's third, and final, season.
He then played a supporting role as Uriah Pedrad in The Divergent Series: Insurgent (2015), the second film in the series, later briefly reprising the role in The Divergent Series: Allegiant (2016). In 2016, his single "Higher" was included on Connor Franta's curated album Common Culture, volume 5. He then appeared in the historical drama The Finest Hours (2016) as Eldon Hanon, the youngest sailor involved in a rescue-at-sea in 1952.
In 2015, Lonsdale auditioned for the role of Jefferson Jackson for The CW's Arrow, but the role was given to Franz Drameh. Instead, he was cast as Wally West (the previously unknown son of Joe West) on CW's The Flash and became a regular supporting character on season two, and as Kid Flash on season three. In 2017, the character left The Flash and debuted on season three of Legends of Tomorrow. That year, Lonsdale also appeared in an episode of Supergirl.
In 2018, Lonsdale played Bram in the film Love, Simon, based on Becky Albertalli's novel Simon vs. the Homo Sapiens Agenda, about a teenage boy who struggles to come out. Lonsdale later said the role helped him come to terms with his own sexuality. The film received positive reviews from critics, and was dubbed historically significant, as it was the first film ever released by a major studio to focus on a gay teenage romance.
In 2019, Lonsdale starred in Camila Cabello's music video for "Liar".
On 19 June 2025, Lonsdale was announced in the cast for a yet to be titled Postcard Bandit series for Foxtel. RUN premiered in Australia on Binge on 1 January 2026, with Lonsdale playing Detective Gary Porter in pursuit of the infamous 'Postcard Bandit'.
