The kangaroo conundrum remains.

- Abstract
1. The management of kangaroo populations is a major land management and conservation issue in many parts of Australia. 2. Viggers & Hearn (2005 ) reported the results of a substantial radio-tracking study of the eastern grey kangaroo ( Macropus giganteus Shaw) in south-eastern Australia. Martin et al. (2007 ) critique the study design, home range analysis, biomass assessment and other aspects of the work by Viggers & Hearn (2005 ). 3. We reject the criticisms made by Martin et al. (2007 ) and believe that the study design employed by Viggers & Hearn (2005 ) was sound. The work also was preceded by extensive day and night-time field assessments to enable contrasts between low and high density M. giganteus populations. We also contend that the home range analysis was not flawed: the methods employed by Viggers & Hearn (2005 ) were in fact the same ones recommended by Martin et al. (2007 ). We believe that other criticisms made by Martin et al. (2007 ) also cannot be sustained. 4. Synthesis and applications. Viggers & Hearn (2005 ) found that patches of remnant native vegetation were used as day and night-time refuges by M. giganteus. This creates a disincentive for farmers to conserve remnant native vegetation. The criticisms by Martin et al. (2007 ) have no bearing on this conclusion; hence the kangaroo conundrum stands.
