IOI guests enter Lone Pine Koala Sanctuary.
IOI guests have met with native Australian wildlife only a day into the event.
More than 20 informatics enthusiasts were taken to Lone Pine Koala Sanctuary in Brisbane on Sunday morning.
The group included informatics students, past-competitors and current computer scientists.
Guests held koalas, fed kangaroos and watched sheep being shorn, among other activities.
For some, such as Estonian student Sandra Schumann, the trip constituted their first Australian experience.
Ms Schumann only arrived in the country on Saturday but was enthusiastic to see animals such as platypuses and the Tasmanian devil.
Guests will go on to visit southeast Queensland galleries, theme parks and Australia Zoo throughout the week.
