[1] Illustrations by Lambert formed part of the bush ballads of the Fair girls and gray horses (1898) and Hearts of gold (1903) anthologies of Scottish-Australian poet Will H. Ogilvie (1869–1963).

Lambert was awarded a silver medal at an international exhibition for his painting The Sonnet in Barcelona in 1911.

[4] During the war years, George Lambert spent much time in London, where it is suggested he was romantically involved with fellow artist Thea Proctor.

Lambert returned to Australia in 1921, where he had success in Melbourne with a one-man show at Fine Art Society gallery.

[5] He submitted a self-portrait for the third year, competing with William Macleod who entered with the subject of The Bulletin cartoonist 'Hop' Hopkins.

In November 1927 he was commissioned to create a statue of writer Henry Lawson; the work depicting Lawson in rough clothes accompanied by a swagman, a dog and a fence post was unveiled in The Domain, Sydney on 28 July 1931 by the Governor of New South Wales, Sir Philip Game.

Their children were Maurice Lambert (1901–1964), a noted sculptor and associate of the Royal Academy, and Constant, the British composer and conductor, born in London in 1905.
