The lucky young adventurer - spending a summer in a foreign city. And of course not just any city - gotta be proud of our city. He will have a ball - and hopefully do some uni work
Across from the Opera House probably means across the harbour to a suburb called Kirribilli. The Opera House is right at Circular Quay on the edge of the CBD, where all the commuter ferries come, so he might be lucky and get a nice spot with a great view.
Kirribilli (as you might expect) is quite an expensive area, mostly high rise - from bed
sitters to large apartments. Ferries, trains and buses are all in walking distance and just near the harbour bridge. There always seems to be a shortage of car spaces there, so many people do without them - transport is so easy and close to the city and nearby Darling Harbour - probably a bit more popular for the young ones.
My daughter is doing a similar thing - international student in Mexico
for a semester - due back in January. She is also doing community stuff - helped a tsunami devastated community in Thailand
and shortly working on a project
to save turtles from extinction in Costa Rica
