Cupcakey, Have you overlooked the information researched for you here in June last year :
TITTERINGTON Miss A 28 years Linen keeper, embarked on the ORAMA from London on 27 Mar 1925. Contracted to land in Sydney. Last address in the UK 48 Lord Street Southport Country of last permanent residence England. Country of intended permanent residence Australia.
I cannot find a marriage to a John RICHMOND between 1925 and 1927. Perhaps they weren’t married and legally she was a spinster at the 1933 marriage.
There is an online tree on Ancestry with a photo of Annie and her dau. Is it your tree cupcake?
Cando
ADD Mr J Steele ticketted to Melbourne, and Miss A Titterington ticketed to Sydney.
err.... about 900 kms between those two capital cities. Huge assumption to match passenger Mr J Steele with Cupcake's Aunt.

ticket numbers show NO connection,

destinations show NO connection,
and

there's 29 pages of passenger names on that voyage; 241 first class, 904 third class including 175 aliens.
