John Henry has another entry in 1925 at Moorlands, Queensland (Not unusual two have two entries if a person moved and hadn't been struck off the first roll)
Hanes Telu gives the son's arrival as:
J H Cuer, age 20, Farm Labourer, sailed 21 Dec 1912 from London aboard the Limerick.
Seems that the son arrived first as there's this arrival for John William:
Ship:
Marathon, departed London 4 Dec, 1913, bound for Brisbane
Mr John Cuer, market gardener, aged 54; ticketed to Brisbane
The
Marathon arrived in Brisbane 26 January 1914
