SS Naldera was a steam-powered passenger liner owned and operated by the Peninsular and Oriental Steam Navigation Company (P&O) between 1920 and 1938.

[5] P&O had the vessel fitted out to the original specification of mail and passenger liner and the ship entered service in April 1920 on the London – Bombay – Australia route.

[7] Among the passengers on this voyage were the Australian team en-route to Amsterdam to compete in the 1928 Summer Olympics.

By 14 October changing circumstances meant that the force was no longer required so the two ships returned to Tilbury.

[5] Apart from the Australian Olympians other passengers carried at various times included Lloyd George on his way to the San Remo conference in 1920,[12] Arthur Conan Doyle who travelled to Australia on the ship in 1920,[13] the Great Britain rugby league team at the start of their 1920 tour to Australia,[14] Rabindranath Tagore who sailed from Bombay on the first leg of a journey to Canada in 1929,[15] and Amy Johnson who returned from her solo flight to Australia by the ship as far as Salonika.
