After many years I convinced my dear wife to make holday in Aussie. Best might be a rental from Britz.

Plan: arrive at Cairns (7 - 8 hours from Tokyo), then go where no people are.
I do not want to see a city and crowds, that we have enough here.
Duration: 2 weeks.
Do you think Cairns is a good starting point?
Had 2 trips to Perth and Cairns to see Daintree Forest abt. 2-3 hours from Cairns to the north (?).
Diving was also included at the great barrier rieff. You have some nice places there to make holidays.
Well, probably it will be July or August this year, which means winter time in your country.

Thanks for any advice to visit your country.
