'Newk: The John Newcombe Story' by Kieran Carroll (2025)
Sydney Theatre Reviews (4 stars)
"Paul Armstrong as Newk is passionate about the material, delivering his lines with a knowing smile and great gusto of energy. Armstrong is eager to please fans and succeeds..."

'Cymbeline' by W. Shakespeare (2024)
Toorak Times
"Iachimo/Belarius (Paul Armstrong) is brilliant. He embodies his characters effortlessly and commands the stage. What a treat to see him in the demanding plays that Robert Johnson directs..."

'Caligula' by Albert Camus (2022)
Theatre Travels
"While every actor in this production performs admirably and is committed to realising the unusual vision of the director, it is worth mentioning a few standout showings. Paul Armstrong’s Cherea is a balanced antagonist, and his chemistry with Liliana Dalton’s mad emperor when clashing heads makes for some incredible scenes throughout the play..."

Lilithia
"If Caligula does have an adversary, it is Cherea (Paul Armstrong). Playing alongside each other, Armstrong’s Cherea is solid and uncompromising in his belief that the young emperor is so far gone, needing to be stopped before more suffering is caused. Dalton is flamboyant and merciless playing Caligula, whereas Armstrong is stoic and retains his compassion despite what Caligula has done..."

TAGG
"Several other actors particularly drew my attention; Paul Robertson, Paul Armstrong, and Karlis Zaid were superb. They were mesmerising..."

'The Seagull' by Anton Chekhov (2017)
Sydney Arts Guide
"The doctor, Dorn (Paul Armstrong) has a duplicitous insouciance that endows the bachelor with a certain rapaciousness..."

'Dead Time' by Fleur Beaupert (2015)
ArtsHub
"The dynamic between Robert Rhode as the charismatic yet sensitive Haneef and Paul Armstrong as his Lawyer Peter Russo is particularly enjoyable, and it’s unfortunate that their bro-mance doesn’t get more performance time...."

'and now to bed' (2015)
Theatre Unzipped
"Up first Paul Armstrong. Calm, sure and direct with brushes of budding nerve endings took us on a journey of bisexuality, love gained, love lost, and love born. A great start to the show and a joy to watch..."

'Amanda' by Mark Langham (2014)
Suzy Goes See
"Paul Armstrong takes on a trio of personalities with good variation and conviction. The actor’s relaxed nature contrasts well with his co-players’ sense of severity, but is also able to inject power and dynamism when required..."

Sydney Arts Guide
"Paul Armstrong gave a very credible performance as a typically hard edged, crusty Detective.…"

'Singled Out' (2013)
Dinner and a Show
"A touching though fleeting performance came from Paul Armstrong in ‘The Lighthouse Keeper’, playing the lonely though complacent protagonist. Like the others, Armstrong’s choices were demonstrative of the theme the show was trying to capture – moments of introspect and revelation. Armstrong and Cox made for a lovely pairing in this particular piece and produced some genuinely heartfelt moments...."

'Three Sisters' by Anton Chekhov (2012)
Stage Whispers
"Ben Dalton as Vershinin, the commanding officer of the base, is more believable. His voice is more modulated and his characterisation more considered. So also is Paul Armstrong as Marsha’s Latin-teacher husband Fyodor. He is suitably pompous and a trifle pathetic as he battles on despite being ridiculed by his sisters-in-law and betrayed by his wife..."
