Dear Sister,
I've settled into life in Australia. Sydney is vibrant, and the people are welcoming. I'm studying at [Name of University/College] and enjoying the diverse culture.
I've explored stunning natural sites like the Great Barrier Reef and the outback. The wildlife is fascinating.
I miss home and our family, but this journey is a valuable experience. I hope you can visit soon.
Take care and stay in touch.
With love,
Name
