  We find the low lying quasinormal mode frequencies of the recently proposed
novel four dimensional Gauss-Bonnet de Sitter black holes for scalar,
electromagnetic and Dirac field perturbations using the third order WKB
approximation as well as Pad\'{e} approximation, as an improvement over WKB. We
figure out the effect of the Gauss-Bonnet coupling $\alpha$ and the
cosmological constant $\Lambda$ on the real and imaginary parts of the QNM
frequencies. We also study the greybody factors and eikonal limits in the above
background for all three different types of perturbations.
