The opener has an average Test score of 43 but averaged just 25 against Australia in last year's Ashes series in England.
South African-born Lamb, who featured in five Ashes series, three of them in Australia, insists Cook and England will need to be strong with the bat if they are to succeed down under.
"The big thing about Australia, and that Kookaburra, is you want to be getting scores of 400," he added.
"If you get 270 you're gone, in England you can get away with it because of the conditions, but that Kookaburra ball gets old and you want to play some big scores."
