[5] Cometti retired as a sports commentator, with his last game being the 2021 AFL Grand Final, which was called for Triple M in Perth on 25 September 2021.
His father was the son of Italian migrants; his paternal grandfather Giovanni Cometti was from the village of Baruffini [it] in Lombardy and moved to Australia to work on the Western Australian Goldfields.
Melbourne station 3KZ needed a caller, and, due to a quirk of fate, Cometti volunteered to sit alongside Ian Major.
[13][14] He also called WAFL football during his time at the national broadcaster either side of his stint as West Perth coach.
In 1988, when Seven regained the VFL television rights, Cometti immediately became the highest profile commentator of VFL/AFL matches (based in Western Australia where he presented the evening news sports segment).
He stayed with Seven until 2001 as main sports anchor for Seven News in Perth, when they lost the rights to broadcast AFL matches.
[14] Along with his football and news commitments Cometti, with the blessing of Channel 7, broadcast a further 51 test matches for the Packer radio network alongside Henry Blofeld, Richie Benaud, Ian and Greg Chappel and Tony Greig.
[15] Cometti switched to the Nine Network in 2002 and alongside Eddie McGuire, Dermott Brereton and Garry Lyon became the channel's leading Australian rules football caller.
[18] Between 2008 and 2011 Cometti was the lead AFL caller on Saturday afternoons for 3AW, initially alongside Rex Hunt and later Brian Taylor.
When Cometti revealed he would be joining Triple M in 2012, he was immediately removed from 3AW's lineup to call the 2011 AFL finals series and was replaced by Dwayne Russell.
[19] Cometti called Saturday afternoon games for Triple M with James Brayshaw, Danny Frawley and Garry Lyon.
After retiring from TV commentary, Cometti continued to call matches for Triple M for games in Western Australia with Lachy Reid, Andrew Embley, Xavier Ellis, and his son, Mark, as the statistician.
[22][23][24] Cometti himself has said his humour is derived from his days trying to entertain listeners on the FM radio broadcasts of his early career as well as teenage afternoons firing off wisecracks from the hill at Perth's Leederville Oval.
[25] Here is an incomplete compendium containing a cavalcade of Cometti's Cometti-isms over his 51-year broadcasting career:[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50] Cometti was featured on SBS in an episode in the first Australian series of Who Do You Think You Are?, where he traced his father's Italian heritage back to Italy and his mother's English heritage back to three convicts and a freeman.
