Travelan Quarterly Net Sales ($ AUD)

Continued growth (+34% on pcp) in Australia can be contributed to: (1) increased awareness and consideration driven by extensive digital and social media marketing. (2) same store growth as a result of increased promotion and past promotions driving new customers and return customers respectively; (3) growth from new stores within banner groups in which we secured core ranging in FY25; (4) increased South East Asian travel.

Q1 sales in the U.S. increased (+44% on pcp) on the back on number of marketing initiatives including: (1) improved Travelan^® store on Amazon.com; (2) local U.S. Travelan^® Facebook and Instagram pages; (3) increased paid social, influencer and organic social media marketing.

Q1 in Canada is typically the lowest travel period during the year. During FY25 we had a Q1 pipeline fill into over a thousand Canada retail doors on the back of securing listings within key pharmacy and grocery retail groups. Sales are expected to pick up on the back of consumer promotions closer to the end of the calendar year when travel typically picks up. We also anticipate increased pull through from stores as we continue to build Travelan brand awareness within Canada though our in-store educational programs, in-store promotions, and social media marketing.
