  We report measurements of the sky-projected spin--orbit angles for three
transiting hot Jupiters: two of which are in nearly polar orbits, WASP-100b and
WASP-109b, and a third in a low obliquity orbit, WASP-72b. We obtained these
measurements by observing the Rossiter--McLaughlin effect over the course of
the transits from high resolution spectroscopic observations made with the
CYCLOPS2 optical fiber bundle system feeding the UCLES spectrograph on the
Anglo-Australian Telescope. The resulting sky-projected spin--orbit angles are
$\lambda = {-7^{\circ}}^{+11^{\circ}}_{-12^{\circ}}$, $\lambda =
{79^{\circ}}^{+19^{\circ}}_{-10^{\circ}}$, and $\lambda =
{99^{\circ}}^{+10^{\circ}}_{-9^{\circ}}$ for WASP-72b, WASP-100b, and
WASP-109b, respectively. These results suggests that WASP-100b and WASP-109b
are on highly inclined orbits tilted nearly $90^{\circ}$ from their host star's
equator while the orbit of WASP-72b appears to be well-aligned. WASP-72b is a
typical hot Jupiter orbiting a mid-late F star (F7 with
$T_\mathrm{{eff}}=6250\pm120$K). WASP-100b and WASP-109b are highly irradiated
bloated hot Jupiters orbiting hot early-mid F stars (F2 with
$T_\mathrm{{eff}}=6900\pm120$K and F4 with $T_\mathrm{{eff}}=6520\pm140$K),
making them consistent with the trends observed for the majority of stars
hosting planets on high-obliquity orbits.
