He is best known as one of the founding members of the Sydney pub rock band the Cockroaches and the Field Brothers and as Managing Director for the children's music group the Wiggles.

Upon leaving school he attained his teaching qualification from Australian Catholic University and a diploma of religious education from Aquinas Academy in Sydney.

John Field's performances on-stage built the Cockroaches' reputation for being a party-band, even though alcohol and drug use was never part of the band's culture.

[8] Australian musicologist Ian McFarland called The Cockroaches "an in-demand pub band [that built] a sweaty, frenzied atmosphere with good old-fashioned showmanship and unpretentious, energetic rock'n'pop".

Anthony formed The Wiggles in 1991, with Murray Cook, Greg Page, and fellow Cockroaches band member Jeff Fatt, and they dedicated their first album to his niece.

[20] 2016 saw the release of The Field Brothers' second album Every Day Is Like an Elvis Movie, which featured cameos from guests including Greedy Smith (Mental As Anything).

The album was preceded by the singles "Valentines Day", a duet with Australian country singer Kasey Chambers, a cover of Bob Dylan's "You Ain't Goin' Nowhere", with Jimmy Barnes and "This Way to Love and Happiness".
