5 largest 1st innings leads after which follow-on was not enforced

#2 445: Australia vs England, Brisbane 2006

Australia did not enforce the follow-on on England at Brisbane in 2006 but went on to win by 277 runs

England had arrived in Australia with the urn belonging to them following the historic Ashes win at home in 2005. But a reality check soon brought them back to earth when the hosts racked up 602/9 in the first innings and they themselves fell for merely 157 in reply. Captain Ricky Ponting had led the way with the bat with a contribution of 196 before Glenn McGrath got into the action with a haul of 6/50, as the only respectable score of 50 came from Ian Bell.

Ponting opted for a bat again in the hope of piling up rapid runs and pressuring England. His openers Justin Langer, who got 100*, and Matthew Hayden obliged and Ponting himself scored 60* as Australia hit 202/1 and asked England to chase down 648. This time, however, England were prepared for a fight, all they could manage was 370 with both Paul Collingwood and Kevin Pietersen missing out on hundreds. Australia won by 277 runs and took a 1-0 lead in a series they would go on to win 5-0.

Brief Scores: Australia 602/9 dec (Ponting 196, Hussey 86; Flintoff 4/99) and 202/1 dec (Langer 100*, Ponting 60*; Flintoff 0/11) beat England 157 (Bell 50; McGrath 6/50, Clark 3/21) and 370 (Collingwood 96, Pietersen 92; Clark 4/72) by 277 runs
