There are of course many many species of Protaceae that aren't mediterranian
or drought-tolerant, including some that are native to tropical and
sub-tropical rainforest, and which can take as much phosphorous as you care
to throw at them. These include the various species of Macadamias, as well
as Grevillea robusta (silky oak), G. baileyana, G. hilliana (all trees), and
many other genera which are probably less widely available. Some Hakeas also
grow in the rainforest, but no Banksias and Leucodendrons AFAIK. For
drought-tolerance (especially dry summers), you should probably stick to
species from inland or SW Australia, or (I presume) the South African veldt.
