{ 1 } - We directly perceive sense data.
{ 2 } - The question about what we "directly perceive" is unclear.
{ 3 } - We directly perceive material objects (a view Austin calls "realism").

The contrast between "direct" and "indirect" perception is unclear. We sometimes speak of "seeing indirectly" (e.g. seeing something's reflection in the mirror) or "hearing indirectly" (e.g. through another's testimony) -- but not of "smelling indirectly" or "tasting indirectly." So "directly perceive" (where "perceive" can cover any of the five senses) doesn't make sense in ordinary speech. And those who use this phrase haven't told us in what special sense they mean it to be taken.
