  We present critical, long-wavelength observations of Eta Carinae in the
submillimetre using SCUBA on the JCMT at 850 and 450 um to confirm the presence
of a large mass of warm dust around the central star. We fit a two-component
blackbody to the IR-submm spectral energy distribution and estimate between
0.3-0.7 solar masses of dust exists in the nebula depending on the dust
absorption properties and the extent of contamination from free-free emission
at the SCUBA wavelengths. These results provide further evidence that Eta
Carinae's circumstellar nebula contains > 10 solar masses of gas, although this
may have been ejected on a longer timescale than previously thought.
