There is a widely held assumption that Australians don't tip, which is not true. We might hate tipping culture but it doesn't mean we don't tip which is appropriate overseas.
When we cruised with a French cruise, CTMA Vacancies, a young member of the crew took it upon herself to tell me I needed to tip extra. No amount of telling her that I had already tipped would convince her. To me tipping is an extra cost, which I pay up front.
Another night in Alaska, at a restaurant on the last night of the cruise season, the young waitress counted her tips, including ours to come, in front of us.
I think you have to be born to tipping to be comfortable with the practice
