A bit of farm work in exchange for hunting rights fosters some goodwill; gifts like food etc are good - especially if there is some specialty you have access to that you can offer. Handmade or otherwise unobtainable commercially is good.
One place I get to semi-regularly in the semi-arid west of NSW has some trees with amazing and beautiful timber (mulga, gidgee, bullock bush etc); I took some branches and trunks one year, and returned the next with a stool fashioned by hand with adze, drawknives, spokeshave, auger etc.
