[8] Farnham has become one of his country's best-known and most popular performers,[1] and he is the only Australian artist to have a number-one record (album or single) in five consecutive decades (echoing that of Cliff Richard in the UK), with singles including "Sadie (The Cleaning Lady)" in 1967, "Raindrops Keep Fallin' on My Head" in 1970, and "Age of Reason" in 1988;[4][5] and albums Whispering Jack in 1986, Age of Reason in 1988, Chain Reaction in 1990, Then Again... in 1993, 33⅓ in 2000, and The Last Time in 2002.

[14][15][16][17] Aside from his recording career, Farnham performed on stage with lead roles in Australian productions of Charlie Girl, Pippin and 1992's Jesus Christ Superstar.

[24] Farnham's first commercially successful recording was a cover of American novelty song "Sadie (The Cleaning Lady)"; Sambell had disliked it, as the lyrics were so persistent.

[16] The clean-cut pop star had made several more albums and singles, but by the mid-1970s his recording career had begun to dwindle and he turned more to stage musicals and television.

[4] During this time, Farnham started supplying vocal tracks for films, including Savage Streets (1984), The Slugger's Wife (1985), and Fletch (1985); he later continued with Rad (1986) and Voyage of the Rock Aliens (1987).

The concert video was only one hour long, and it highlighted some of the songs from The Net as well as reworked versions of Little River Band classics such as "Cool Change" and "Reminiscing".

"Please Don't Ask Me", a song written by Goble,[43] and a non-top 50 single for Farnham almost three years previously,[4] was played during the "Australian-themed" opening of the show.

Sound engineer Ross Fraser suggested to Farnham's manager Glenn Wheatley that it was time to start working on the solo album.

[16] Initially, public interest in the re-branded former teen idol was difficult to cultivate, and radio stations refused to play Farnham's album.

[52] The song was written by Andy Qunta (ex-Icehouse), Keith Reid (Procol Harum), Maggie Ryder and Chris Thompson (ex-Manfred Mann's Earth Band).

[12] In March 1989, Farnham was in Moscow, USSR to promote Greenpeace album Rainbow Warriors, as part of an international ensemble including David Byrne (Talking Heads), Peter Gabriel, Chrissie Hynde (The Pretenders), Annie Lennox (Eurythmics), and The Edge (U2).

1 on the Australian album charts, it provided three Top Ten hit singles, "Chain Reaction" in August, "That's Freedom" in September and "Burn for You" in December.

[5] Unlike the previous two albums, where most songs were written by outside writers, Chain Reaction saw Farnham write nine of its twelve tracks with Fraser and keyboardist/musical director David Hirschfelder (ex-Little River Band) along with Phil Buckle ("Burn For You") and Joe Crighton ("The Time Has Come").

[1][65] Fellow cast members included Angry Anderson as Herod, Kate Ceberano as Mary Magdalene, Russell Morris as Simon Zealotes, Jon Stevens as Judas and John Waters as Pontius Pilate.

In a TV Week interview promoting the Romeo's Heart album, he said that people had put pressure on him to live overseas but he had no intention of doing so.

[5] On 21 December, Farnham performed a set for the Tour of Duty concert in Dili for the Australian troops serving with InterFET and East Timorese people.

[9] The concert included James Blundell, Dili Allstars, Gina Jeffreys, The Living End, Kylie Minogue, Doc Neeson and the RMC Band.

In 2002, Farnham announced his decision to retire from full-scale national tours after his The Last Time Tour—he would still perform in concerts and record—which commenced on 6 November 2002 and finished on 15 June 2003.

[71] During July 2003, Farnham worked with Queen to produce a new version of "We Will Rock You" for the 2003 Rugby World Cup,[72] released on his greatest hits album, "One Voice".

[11] Combining with singer Tom Jones, Farnham undertook the Together in Concert series during 2004 with ten shows in Perth, Sydney, Brisbane, and Melbourne.

Duets started with "That Driving Beat" and "Mama Told Me Not to Come", solos from Farnham were "One", "Pressure Down", "That's Freedom", "Heart's on Fire", "Playing to Win", "Every Time You Cry", "Man of the Hour", "Age of Reason", and "Burn for You".

The pair did five duets to close the show—Sam and Dave's "Hold On I'm Coming", Otis Redding's "Try a Little Tenderness", Ray Charles' "What'd I Say", Arthur Conley's "Sweet Soul Music" and AC/DC's anthem, "Long Way to the Top".

[79] Farnham made an appearance during the 2005 Melbourne Music Festival, raising funds for rebuilding after the 2004 Indian Ocean earthquake at the Tsunami Benefit Concert.

[81] From 18 February, Farnham embarked on a small Australian tour with Fleetwood Mac singer Stevie Nicks for a series of live shows.

[citation needed] On 26 March, Farnham sang at the 2006 Commonwealth Games Closing Ceremony,[80] in Melbourne starting with his hit "Age of Reason", followed by "I Remember When I Was Young" from his most recent studio album, "Playing to Win" from his Little River Band days and finished with his anthem song, "You're the Voice".

[citation needed] The twentieth anniversary of Whispering Jack in 2006 was marked by an "enhanced" commemorative CD re-release plus a DVD featuring an edited version of the tour that accompanied the album (the full concert was originally released on VHS in 1987).

[citation needed] On 8 June 2011, it was announced that Farnham intended to embark on a nationwide tour of Australia throughout October and November 2011 to celebrate the 25th anniversary of the release of the Whispering Jack album.

[93] The song plays as a soundtrack for a video ad directed by filmmaker Warwick Thornton, which was rolled out on social and other digital media and television.

[96][97] Farnham has supported several charities over the years, including headlining the 2019 Hay Mate series of concert for Australia's farming community, which raised over 4.4 million dollars.

"[99] In 2015, Farnham, along with AC/DC, Newton John, the Seekers, and Indigenous Australian artist Archie Roach, was inducted into the Music Victoria Hall of Fame.
