That should not be a problem.
I revised my Australian will about two years ago, during COVID. Done via Zoom meetings, and emails. The witness signatures of two Thai staff at my condo were acceptable.
Unless the law has changed post-COVID, of course.
I have burned a bridge with only one friend, a Roman Catholic. He became a climate change denier, and was denouncing Greta Thunberg as brain-washed by her parents. I asked him to explain the difference between her parents, and those parents who send their children to private Catholic schools. He stormed off, we have not spoken since.
I still have about half-a-dozen good friends in Australia, we stay in touch. Sadly, several more have passed away. I miss them.
