Abstract Objective Compare the adoption and adherence to health protection behaviours prior to and during travel among international Australian travellers who return to Australia with notified chikungunya or malaria infection. This information could inform targeted health promotion and intervention strategies to limit the establishment of these diseases within Australia. Results Seeking travel advice prior to departure was moderate (46%, N = 21/46) yet compliance with a range of recommended anti-vectorial prevention measures was low among both chikungunya and malaria infected groups (16%, N = 7/45). Reasons for not seeking advice between groups was similar and included ‘previous overseas travel with no problems’ (45%, N = 9/20) and ‘no perceived risk of disease’ (20%, N = 4/20). Most chikungunya cases (65%, N = 13/20) travelled to Indonesia and a further 25% (N = 5/20) visited India, however most malaria cases (62%, N = 16/26) travelled to continental Africa with only 12% (N = 3/26) travelling to India. The majority (50%, N = 10/20) of chikungunya cases reported ‘holiday’ as their primary purpose of travel, compared to malaria cases who most frequently reported travel to visit friends and family (VFR; 42%, N = 11/26). These results provide import data that may be used to support distinct public health promotion and intervention strategies of two important vector-borne infectious diseases of concern for Australia.
