The mother of an Australian veterinarian killed in Namibia has paid tribute to her "sunny, focused and driven" daughter.
Jarrah Young, 27, from the Gold Coast, was killed when a tour bus she was travelling on crashed in Usakos.
Brisbane nurse Sarah Penberthy, 22, also died in the accident.
A number of other tourists, including several Australians, were injured.
Young's mother, Andrea Harris, said her daughter had been working in Kenya for the past year and lived life to the full.
