Hello Wildflower,
If you would like to know more about the Australian tour, you can find out from the Reviews section in this forum. I always do the research this way before booking.
I am originally from India, arrived here more than half a century ago. Good to know that you are enjoying your visits there. I have visited most parts of India, but not Darjeeling. It is on my bucket list, so do write your thoughts about the trip.
