Given the rapid growth of domestic tourism in the Malaysian tourism industry, this study aims to examine the determinants of domestic travel frequency. The censored Tobit model was used on primary data collected from Penang Island residents. Results indicate that age, race, education-level, and average-number-of-days-spent significantly increase domestic travel frequency ceteris-paribus. The results shown provide tourism policymakers with a better understanding of the habits and attitudes of Malaysians vis-à-vis domestic tourism.
