Randell was born in
Hobart, Tasmania. He umpired 36
Test matches between 1984 and 1998, the highest number by an Australian umpire to that time (the previous highest was
Tony Crafter's 33 matches). His umpiring debut was the
Fourth Test between
Australia and the
West Indies at
Melbourne from 22 to 27 December 1984. Randell's fellow umpire in that match was
Peter McConnell. In 1994, the
International Cricket Council introduced a policy of appointing one umpire to each Test match from a non-participating country. Ten of Randell's matches were played outside Australia, and did not involve Australia. His last Test match involving Australia was against
South Africa at
Adelaide on 30 January to 3 February 1998, finishing in a draw, with captain
Mark Taylor dominating the first innings with 169 and
Mark Waugh scoring a century in the second innings. Randell's umpiring colleague in that match was a New Zealander,
Doug Cowie. Randell's last Test match was between
Zimbabwe and
Pakistan at
Harare on 21–25 March 1998. Randell umpired 88
One Day International (ODI) matches between 1984 and 1998. He also umpired one women's ODI, in 1991. Altogether, he umpired 119 first-class matches in his career between 1980 and 1998. At the club level, Randell was a left-hand batsman for the South Hobart and Sandy Bay clubs. Off the field he was a school-teacher with the Tasmanian Education Department. ==Sexual assault conviction==
