To ensure a successful meeting with Mr. Sharma, Mary should consider the cultural differences between Indian and Australian business etiquette. She should dress formally, but also be prepared for flexibility in scheduling.

Additionally, Mary should recognize that Indian decision-making is often impulsive and influenced by family or friends, whereas Australians tend to be more rational. By doing her homework on presentation and being open to suggestions and advice, Mary can increase the chances of a successful meeting with Mr. Sharma.
