  In the context of the unified model of Seyfert galaxies, we use observations
from the literature and a radiative transfer model to investigate the near-IR
to mm emission produced by the presumed torus in the Circinus galaxy, from
2microns to 1.3mm. From the infrared SED modelling, we find that the total
luminosity (L_{IR}) in this wavelength range, consists of similar contributions
from the torus and starburst with a ratio of nuclear luminosity to starburst
luminosity (L_{NUC}/L_{SB}) approx. 0.8.
  By using a similar torus model to that of NGC1068, but without the conical
dust, we find an upper limit to the outer torus radius of approx. 12pc with a
best fit of approx. 2pc. The upper limit torus size estimated from the
radiative transfer modelling is consistent with the 16pc torus radius estimated
from near-IR imaging polarimetry of Circinus.
