  We have developed a galaxy cluster finding technique based on the Delaunay
Tessellation Field Estimator (DTFE) combined with caustic analysis. Our method
allows us to recover clusters of galaxies within the mass range of 10^12 to
10^16 Msun. We have found a total of 113 galaxy clusters in the Galaxy and Mass
Assembly survey (GAMA). In the corresponding mass range, the density of
clusters found in this work is comparable to the density traced by clusters
selected by the thermal Sunyaev Zel'dovich Effect; however, we are able to
cover a wider mass range. We present the analysis of the two-point correlation
function for our cluster sample.
