As well, Paul Keating's eulogy for the unknown soldier will be immortalised in bronze.

It will be unveiled on Remembrance Day by Mr Keating, two decades after he delivered the poignant address.

Director Brendan Nelson revealed the developments on Wednesday at the National Press Club.

He is also working on a Roll of Honour ''soundscape'' project, where primary school students will record the names and ages of the 62,000 Australians who died in World War I. The recordings will be played in that war's section of the roll.

Dr Nelson, who became director at the end of last year, introduced a daily Last Post ceremony and, for the Anzac Day dawn service, had readings of war diaries, with names of battlefields projected on to the building.

Now he wants to commemorate the 62,000 killed by projecting their names on the building every night during the four year centenary of Anzac and playing a recording of the names.

Dr Nelson, a former Liberal leader, said he considered Mr Keating's eulogy as ''one of the most significant speeches given by any Australian prime minister in any era since Federation''.

''I said to Paul Keating recently that not only will it stand the test of time, it already has,'' Dr Nelson said.

The remains of an unknown Australian soldier killed in World War I were returned from France in 1993, and buried in a tomb within the memorial to represent all Australians who have died in wars.

One end of the tomb reads, ''Known Unto God'', and the other, ''He symbolises all Australians who have died in war''.

Dr Nelson said those lines would be removed and replaced with stone from the same quarry reading ''We do not know this Australian's name, we never will'' and ''He is one of them, and he is all of us''. The former is a variation on the opening line of Mr Keating's famous eulogy.

Mr Keating will deliver the commemorative address on Remembrance Day this year, when the refurbished tomb is officially inaugurated.
