Again, in the spirit of elimination.....
The man arriving 1912 was Albert L BROWN, born abt 1883. Middle initial only.
There a only a handful of Albert L* BROWN(E) births registered England 1880-1886:-
Albert Londes BROWNE in Canterbury 1881
Albert Langton BROWN in Guisbro, 1880
Albert Lidgertwood BROWN, in Warwick, 1882, mms EVEMY
Albert Lyne BROWN, in Fulham 1884
Albert Leopold BROWN, in Holywell 1885
Of them, of note is:
Albert Lidgertwood BROWN, in Warwick, 1882, mms EVEMY
He died in Queensland Australia in 1930. his mms matches on Australian Death Index and he's buried in Lutwyche Cemetery, Brisbane.

In 1901 at age 18, he was a Commercial Clerk, living in Hampstead
In 1909, he married 1909 in Hampstead, England to Margaret Mary CUBITT.
His Occupation: Clerk. Her occupation was Tailoress.
In 1928, he and Margaret are in Kelvin Grove, Lilley QLD. He's a Farmer.
My money is on him being the fellow arriving in Brisbane on the 1912 Passenger list......
Passenger Albert L BROWN in 1912 was a Store Manager. I think the fit is pretty neat.
And more:
Albert Lidgertwood BROWN and his wife Margaret Mary CUBBIT had a daughter Joan E M BROWN born 1910, Barnet .
Margaret BROWN (28), a Milliner, and Joan E BROWN (2½) departed London on 14th March 1913 bound for Brisbane. Just the pair of them - and on the SS ORSOVA.
