After graduating from Flinders University in South Australia and spending time overseas driving trucks, Greig arrived in Melbourne and began working for the Australian Performing Group and 3RRR-FM.

The radio station encouraged him to use his knowledge of popular music to develop innovative programmes and allowed him time to explore sports broadcasting.

This eventually led to the creation of H.G. Nelson a character he was born to play.

Since 1986 Greig has appeared as H.G. Nelson in various radio and television programmes usually with John Doyle appearing alongside him behind the card table as Rampaging Roy Slaven.

This Sporting Life was a regular weekend fixture on the ABC’s Triple J for 22 years, which was followed by five years on Triple M with The Life and The Sporting Probe and Just Short of a Length with Roy and H.G on Macquarie Sports Radio.

During this three-decade run John and Greig have presented a number of television shows including This Sporting Life (the TV show), Club Buggery, The Channel Nine Show, Win Roy and H.G.’s Money, The Dream, The Ice Dream, The Dream in Athens, The Monday Dump, The Cream , The Memphis Trousers Half Hour and The Russian Revolution amongst many others.

In recent years Greig has worked on a wide variety of television including covering sport for The Project, Bush Slam, It’s a Knockout, Who Do You Think You Are?, Home Delivery, Secrets of Our Cities and The Weekly with Charlie Pickering.

Books include H.G.’s Fair Dinkum! Aussie Slang and History of Australia through Sport.

Greig can currently be heard on Bludging on the Blindside with Roy and H.G on ABC Radio.
