Isomers with three- and five-nucleon-hole configurations have beenestablished in $^{203}$Tl. These include newly identified levels with athree-nucleon structure: {\it I}$^{\pi }$ = (15/2$^{-}$) with {\it T}$_{1/2}$ =7.9(5) ns, and {\it I}$^{\pi }$ = (35/2$^{-}$) with {\it T}$_{1/2}$ = 4.0(5)ns. In addition, five-quasiparticle states: {\it I}$^{\pi }$ = (39/2$^{-}$)with {\it T}$_{1/2}$ = 1.9(2) ns, and {\it I}$^{\pi }$ = (49/2$^{+}$) with {\itT}$_{1/2}$ = 3.4(4) ns have also been established. The previously determinedlong-lived decay [{\it T}$_{1/2}$ = 6.6(3) $\mu $s from this work] isassociated with isomerism of the {\it I}$^{\pi }$ = (29/2$^{+}$) state. Levelsabove this long-lived isomer have been identified through a delayed-promptcoincidence measurement. Five-nucleon-hole states with excitation energies {\itE}$_{x}$ $\approx $ 7 MeV have been established as well as possible octupoleexcitations of the $^{208}$Pb core built on these levels. The level scheme of$^{203}$Tl is extended up to {\it E}$_{x}$ $\approx $ 11 MeV with the inclusionof 25 new transitions. Empirical and shell-model calculations have beenperformed to aid in the description of the observed states which are found tobe predominantly of intrinsic character.
