  We investigate the clustering properties of Lyman-break galaxies (LBGs) at
$z\sim6$ - $8$. Using the semi-analytical model {\scshape Meraxes} constructed
as part of the Dark-ages Reionization And Galaxy-formation Observables from
Numerical Simulation (DRAGONS) project, we predict the angular correlation
function (ACF) of LBGs at $z\sim6$ - $8$. Overall, we find that the predicted
ACFs are in good agreement with recent measurements at $z\sim 6$ and $z\sim
7.2$ from observations consisting of the Hubble eXtreme Deep Field (XDF), the
Hubble Ultra-Deep Field (HUDF) and Cosmic Assembly Near-infrared Deep
Extragalactic Legacy Survey (CANDELS) field. We confirm the dependence of
clustering on luminosity, with more massive dark matter haloes hosting brighter
galaxies, remains valid at high redshift. The predicted galaxy bias at fixed
luminosity is found to increase with redshift, in agreement with observations.
We find that LBGs of magnitude $M_{{\rm AB(1600)}} < -19.4$ at $6\lesssim z
\lesssim 8$ reside in dark matter haloes of mean mass $\sim 10^{11.0}$-
$10^{11.5} M_{\rm \odot}$, and this dark matter halo mass does not evolve
significantly during reionisation.
