In
appointing Douglas to the upper house, Lilley consigned Douglas 
to a chamber in which any comments he made would be less damaging.  The position of postmaster-general involved
managing a complex department and the expenditure of considerable time and
energy, and by assigning him this responsibility Lilley hoped Douglas would
have less time and energy to devote, either deliberately or inadvertently, to
destabilising the ministry.
When Douglas ’s appointment was announced, the Brisbane
Courier marvelled that “the suasion and blandishments to induce” Douglas
and Fitzgerald to work together were “inconceivable.”[2]  What were these “suasion and
blandishments”?  While not made public at
the time, the journalist William Coote later revealed that Douglas :
would undertake the leadership of the upper house for a
session;  but he must be
compensated.  At the close of that
session he must have the immigration agency in London 
This
arrangement suited both men.[4]  Douglas 
needed an ongoing salaried position to service debt incurred when selling his Tooloombah
property, and welcomed the status and prestige the position would bring.[5]  Despatching Douglas to Britain  benefited Lilley as well, for it removed
him from the Queensland Douglas  inside the cabinet in preference to having him
cause damage from the backbenches or as a member of the opposition, Lilley
cleverly engineered a plan to remove him altogether.  This arrangement was never made public.

disingenuously observing that his appointment to this position was “far from
being expected.”  (“Farewell Banquet to

[4] Douglas  later confirmed this
arrangement and also revealed that, at various times, Mackenzie, Fitzgerald and
Lilley had all offered him the post of agent-general for immigration.  However, Mackenzie’s government fell before Douglas  could accept, while he declined Fitzgerald’s
offer.
